One critical login + problem is fixed, and a problem with interoperability with + Microsoft software is worked around. + +Major Changes: + +* The one-character bug introduced into the login.krb5 program that + caused 8-character usernames to be rejected in some circumstances + has been fixed. + +* The handling of key version numbers has been modified in places. + The current formats of the keytab and srvtab files, as well as parts + of the remote kadmin protocol, handle key version numbers as 8-bit + quantities, when in fact they are 32-bit quantities. + + * In the keytab and srvtab support for krb5, searching for the + "highest numbered" key version now has some heuristics to deal + with the 8-bit kvno wrapping from 255 to 0 to 1.... If a kvno + greater than 240 is found, the kvno values are assumed to range + from 128 to 383 (127+256). This should handle cases like storing + kvno values 255 and 256 in the file. + + * In the keytab and srvtab support for krb5, when looking for a key + with a specific version number, the low 8 bits of the requested + kvno are compared against the value stored in the file. + + * The "ktutil" program also has a new heuristic for choosing the + "highest numbered" key in a keytab to be written out into a krb4 + srvtab file. + + These heuristics all assume that key version numbers will be + assigned sequentially, and that there will not be a large set of key + version numbers in use at one time for any given principal in a + keytab file. + + These changes were prompted by the discovery by Microsoft (while + trying to write tools to generate MIT-style keytab files) that we + could not store arbitrary 32-bit version numbers for keys. + +Minor Changes: + +* A few compilation problems have been fixed. + +* New test cases have been added to the test suite to exercise some of + the new changes. + +Known Bugs: + +* Non-sequential key version numbering will confuse the new kvno + handling heuristics. + +* Long-standing but newly recognized: + + * The remote kadmin protocol will produce incorrect results when key + version numbers greater than 255 are being retrieved or stored. + The kadmin.local program does not suffer from this problem. + + * We do not support storing multiple key versions for a principal in + a srvtab file. + + * We do not support acquiring krb4 tickets using a srvtab or keytab + file without acquiring krb5 tickets at the same time (i.e., the + old krb4 "ksrvtgt" program). + +* most of the other known bugs from 1.2.3 + +Notes, Major Changes, and Known Bugs for 1.2.3 +---------------------------------------------- + +Notes: + +* This release is a patch release; some non-critical bugs and feature + requests have not been incorporated. We have focussed mainly on + important security fixes and usability fixes. + +Major Changes: + +* Certain problems with shared library builds have been eliminated or + reduced on Linux and HP-UX. + +* Various bugs in single-DES enctype similarity have been fixed; the + 1.0.x behavior of treating all single-DES enctype as equivalent has + been restored for now. This may go away in a future release. Note + that SUPPORT_DESMD5 will be treated as always false for now. + +* The KDC will now log a number of enctype parameters associated with + KDC requests, in order to allow easier debugging of enctype-related + problems. + +* A client will no longer attempt obtain a forwarded TGT with a + session key enctype that the target server won't understand. + +* Triple-DES should work on Windows now. The SHA-1 implementation had + a Windows-specific bug preventing it from working in most cases. + +* Various bugs in pty handling have been fixed. + +* Bogus utmp files with garbage characters in their names should not + get created on Solaris. Also, utmp/wtmp handling code has been + mostly rewritten, eliminating numerous bugs. + +* Potential buffer-overrun problems and null-pointer dereferences have + been fixed in ftpd, telnetd, login.krb5, and SHA-1. The first three + may be exploitable under certain conditions; the SHA-1 bug probably + isn't, as far as we know. + +* For multiple-hop interrealm authentication, the realm transit path + checking has been rewritten. The old code had a serious bug where + some of the transited realms may not have been checked against the + computed path. It was therefore possible to forge a remote client + name in certain cases. We strongly recommend updating application + server code where non-local principals may be found on ACLs. + +* In conjunction with the above fix, we've implemented KDC checking of + the realm transit path, as described in the IETF's current + kerberos-revisions draft, and set up the KDC to refuse to issue + tickets with unacceptable transit paths. (Strictly speaking, + according to the Kerberos specification, enforcement of these checks + is supposed to be left to the application servers.) Thus, if your + application servers can't be updated promptly but your KDC can, you + can still prevent such tickets from being issued. This checking is + controlled by a per-realm flag, and is enabled by default. + +* On AIX systems, the rlogin server should no longer hang when + control-C is pressed. + +* New databases will be created in btree format by default. We + believe the btree code to be less buggy than the hash format code we + have been using. This should not affect the use of any existing + databases, only newly created ones, and even that should be a + transparent change. + +Known Bugs: + +* There may be problems with running a KDC on 64-bit platforms + (environments where size_t and long are wider than 32 bits, such as + alpha/Tru64, or Solaris/SPARC in SPARCv9 mode, for example), as + indicated by the util/db2 tests not passing. These problems may + also extend to the rpc library, which may prevent the kadmin + protocol from functioning. These are being investigated. + +* ETYPE_INFO preauthentication data returned from the KDC are not + sorted in the order requested by the client. This may result in + preauthentication failure when encrypted timestamp preauthentication + is required but the client doesn't understand some of the enctypes + of the keys stored for it in the database. + +* The gssftp daemon and client, when running in krb4 mode, are + inconsistent with respect to port numbers passed to the + {mk,rd}_{priv,safe} functions. As a result, there is a small but + nonzero probability that krb4 ftp with client and server on the same + IP address will fail with a "Time is out of bounds" error. This + includes the tests/dejagnu test suite, which tests the krb4 ftp + functionality. The probability of this occuring seems to be less + than 50%. + +* The gss-sample test application suite is known to not communicate + with the gss-sample suite in 1.1.x and earlier releases. This is + the result of changes to increase functionality; fixes to allow for + backwards compatibility will occur in a later release. + +* BSD/OS 4.x may have some problems compiling. These are being + investigated. + +Notes, Major Changes, and Known Bugs for 1.2.2 +---------------------------------------------- + +Notes: + +* This release is a patch release; some non-critical bugs and feature + requests have not been incorporated. + +Major Changes: + +* The KDC dump format has been updated to include per-principal policy + information. This will require updating your slave KDCs before your + master if you want things to still work. + +* A library bug that prevented kprop from working properly with DES3 + keys has been fixed. + +* kpasswd should no longer coredump when there is no kadmin_server + line in krb5.conf. + +* ASN.1 parsing has been improved to deal with indefinite encodings, + such as those emitted by DCE-1.0 derived systems. + +* Preauthentication handling code in the initial ticket APIs has been + fixed to handle zero-length ETYPE_INFO sequences without causing a + NULL pointer dereference. + +* The replay cache should no longer leak temporary files. Related + hard-to-analyze filename bugs in the rcache code should also be + fixed. + +* Library builds should now work on AIX. + +* KDC local address search code should now work on AIX. + +* The yacc grammar for the ftp daemon has been modified to be + compilable on HP/UX with Bison; namespace pollution from system + headers was causing trouble before. + +Known Bugs: + +* The gss-sample test application suite is known to not communicate + with the gss-sample suite in 1.1.x and earlier releases. This is + the result of changes to increase functionality; fixes to allow for + backwards compatibility will occur in a later release. + +* Handling of utmp and utmpx updates is known to be broken on some + systems, such as Solaris 8. We are investigating possible solutions + to this problem. + +* Tru64 Unix 5.0 (aka OSF/1 5.0), at least, has some problems with + revoke() returning ENOTTY in open_slave in the pty library. One + possible workaround is to insert + + vfs: + revoke_tty_only = 0 + + in /etc/sysconfigtab. It is not known whether this workaround will + cause other problems. + +* BSD/OS 4.x may have some problems compiling. These are being + investigated. + +Notes, Major Changes, and Known Bugs for 1.2.1 and 1.2 +------------------------------------------------------ + +* Triple DES support, for session keys as well as user or service + keys, should be nearly complete in this release. Much of the work + that has been needed is generic multiple-cryptosystem support, so + the addition of another cryptosystem should be much easier. + + * GSSAPI support for 3DES has been added. An Internet Draft is + being worked on that will describe how this works; it is not + currently standardized. Some backwards-compatibility issues in + this area mean that enabling 3DES support must be done with + caution; service keys that are used for GSSAPI must not be updated + to 3DES until the services themselves are upgraded to support 3DES + under GSSAPI. + +* DNS support for locating KDCs is enabled by default. DNS support + for looking up the realm of a host is compiled in but disabled by + default (due to some concerns with DNS spoofing). + + We recommend that you publish your KDC information through DNS even + if you intend to rely on config files at your own site; otherwise, + sites that wish to communicate with you will have to keep their + config files updated with your information. One of the goals of + this code is to reduce the client-side configuration maintenance + requirements as much as is possible, without compromising security. + + See the administrator's guide for information on setting up DNS + information for your realm. + + One important effect of this for developers is that on many systems, + "-lresolv" must be added to the compiler command line when linking + Kerberos programs. + + Configure-time options are available to control the inclusion of the + DNS code and the setting of the defaults. Entries in krb5.conf will + also modify the behavior if the code has been compiled in. + +* Numerous buffer-overrun problems have been found and fixed. Many of + these were in locations we don't expect can be exploited in any + useful way (for example, overrunning a buffer of MAXPATHLEN bytes if + a compiled-in pathname is too long, in a program that has no special + privileges). It may be possible to exploit a few of these to + compromise system security. + +* Partial support for IPv6 addresses has been added. It can be + enabled or disabled at configure time with --enable-ipv6 or + --disable-ipv6; by default, the configure script will search for + certain types and macros, and enable the IPv6 code if they're found. + The IPv6 support at this time mostly consists of including the + addresses in credentials. + +* A protocol change has been made to the "rcmd" suite (rlogin, rsh, + rcp) to address several security problems described in Kris + Hildrum's paper presented at NDSS 2000. New command-line options + have been added to control the selection of protocol, since the + revised protocol is not compatible with the old one. + +* A security problem in login.krb5 has been fixed. This problem was + only present if the krb4 compatibility code was not compiled in. + +* A security problem with ftpd has been fixed. An error in the in the + yacc grammar permitted potential root access. + +* The client programs kinit, klist and kdestroy have been changed to + incorporate krb4 support. New command-line options control whether + krb4 behavior, krb5 behavior, or both are used. + +* Patches from Frank Cusack for much better hardware preauth support + have been incorporated. + +* Patches from Matt Crawford extend the kadmin ACL syntax so that + restrictions can be imposed on what certain administrators may do to + certain accounts. + +* A KDC on a host with multiple network addresses will now respond to + a client from the address that the client used to contact it. The + means used to implement this will however cause the KDC not to + listen on network addresses configured after the KDC has started. + +Minor changes +------------- + +* The shell code for searching for the Tcl package at configure time + has been modified. If a tclConfig.sh can be found, the information + it contains is used, otherwise the old searching method is tried. + Let us know if this new scheme causes any problems. + +* Shared library builds may work on HPUX, Rhapsody/MacOS X, and newer + Alpha systems now. + +* The Windows build will now include kvno and gss-sample. + +* The routine krb5_secure_config_files has been disabled. A new + routine, krb5_init_secure_context, has been added in its place. + +* The routine decode_krb5_ticket is now being exported as + krb5_decode_ticket. Any programs that used the old name (which + should be few) should be changed to use the new name; we will + probably eliminate the old name in the future. + +* The CCAPI-based credentials cache code has been changed to store the + local-clock time of issue and expiration rather than the KDC-clock + times. + +* On systems with large numbers of IP addresses, "kinit" should do a + better job of acquiring those addresses to put in the user's + credentials. + +* Several memory leaks in error cases in the gssrpc code have been + fixed. + +* A bug with login clobbering some internal static storage on AIX has + been fixed. + +* Per-library initialization and cleanup functions have been added, + for use in configurations that dynamically load and unload these + libraries. + +* Many compile-time warnings have been fixed. + +* The GSS sample programs have been updated to exercise more of the + API. + +* The telnet server should produce a more meaningful error message if + authentication is required but not provided. + +* Changes have been made to ksu to make it more difficult to use it to + leak information the user does not have access to. + +* The sample config file information for the CYGNUS.COM realm has been + updated, and the GNU.ORG realm has been added. + +* A configure-time option has been added to enable a replay cache in + the KDC. We recommend its use when hardware preauthentication is + being used. It is enabled by default, and can be disabled if + desired with the configure-time option --disable-kdc-replay-cache. + +* Some new routines have been added to the library and krb5.h. + +* A new routine has been added to the prompter interface to allow the + application to determine which of the strings prompted for is the + user's password, in case it is needed for other purposes. + +* The remote kadmin interface has been enhanced to support the + specification of key/salt types for a principal. + +* New keytab entries' key values can now be specified manually with a + new command in the ktutil program. + +* A longstanding bug where certain krb4 exchanges using the + compatibility library between systems with different byte orders + would fail half the time has been fixed. + +* A source file under the GPL has been replaced with an equivalent + under the BSD license. The file, strftime.c, was part of one of the + OpenVision admin system applications, and was only used on systems + that don't have strftime() in their C libraries. + +* Many bug reports are still outstanding in our database.

This +algorithm is more secure, but encryption is much slower. We expect to +add other, faster encryption algorithms at some point in the future. + +Release 1.1 had some support for triple-DES service keys, but with +release 1.2 we have added support for user keys and session keys as +well. Release 1.0 had very little support for multiple cryptosystems, +and some of that software may not function properly in an environment +using triple-DES as well as plain DES. + +Because of the way the MIT Kerberos database is structured, the KDC will +assume that a service supports only those encryption types for which +keys are found in the database.

Abstract + + The MIT Kerberos 5 release version 1.2 includes support for + triple-DES with key derivation [KrbRev]. Recent work by the EFF + [EFF] has demonstrated the vulnerability of single-DES mechanisms + to brute-force attacks by sufficiently motivated and well-funded + parties. + + The GSSAPI Kerberos 5 mechanism definition [GSSAPI-KRB5] + specifically enumerates encryption and checksum types, + independently of how such schemes may be used in Kerberos. In the + long run, a new Kerberos-based mechanism, which does not require + separately enumerating for the GSSAPI mechanism each of the various + encryption types defined by Kerberos, is a better approach. + Efforts to produce such a specification are under way. + + In the interest of providing increased security in the near term, + however, MIT is adding support for triple-DES to the existing + mechanism implementation we ship, as described here. + +2. New Algorithm Identifiers + + One new sealing algorithm is defined, for use in WRAP tokens: + + 02 00 - DES3-KD + + This algorithm uses triple-DES with key derivation, with a usage + value KG_USAGE_SEAL. Padding is still to 8-byte multiples, and the + IV for encrypting application data is zero. + + One new signing algorithm is defined, for use in MIC, Wrap, and + Delete tokens: + + 04 00 - HMAC SHA1 DES3-KD + + This algorithm generates an HMAC using SHA-1 and a derived DES3 key + with usage KG_USAGE_SIGN, as (should be described) in [KrbRev]. + [XXX: The current [KrbRev] description refers to out-of-date I-Ds + from Marc Horowitz. The text in [KrbRev] may be inadequate to + produce an interoperable implementation.] + + The checksum size for this algorithm is 20 octets. See section 4.3 + below for the use of checksum lengths of other than eight bytes. + +3. Key Derivation + + For purposes of key derivation, we add three new usage values to the + list defined in [KrbRev]; one for signing messages, one for + sealing messages, and one for encrypting sequence numbers: + + #define KG_USAGE_SEAL 22 + #define KG_USAGE_SIGN 23 + #define KG_USAGE_SEQ 24 + +4. Adjustments to Previous Definitions + +4.1. Quality of Protection + + The GSSAPI specification [GSSAPI] says that a zero QOP value + indicates the "default". The original specification for the + Kerberos 5 mechanism says that a zero QOP value (or a QOP value + with the appropriate bits clear) means DES encryption. + + Rather than continue to force the use of plain DES when the + application doesn't use mechanism-specific QOP values, the better + choice appears to be to redefine the DES QOP value as some non-zero + value, and define a triple-DES value as well. Then a zero value + continues to imply the default, which would be triple-DES + protection when given a triple-DES session key. + + Our values are: + + GSS_KRB5_INTEG_C_QOP_HMAC_SHA1 0x0004 + /* SHA-1 checksum encrypted with key derivation */ + + GSS_KRB5_CONF_C_QOP_DES 0x0100 + /* plain DES encryption */ + GSS_KRB5_CONF_C_QOP_DES3_KD 0x0200 + /* triple-DES with key derivation */ + + Rather than open the question of whether to specify means for + deriving a key of one type given a key of another type, and the + security implications of whether to generate a long key from a + shorter one, our implementation will simply return an error if the + QOP value specified does not correspond to the session key type. + + [XXX: Not implemented yet. Currently an error is reported for all + non-zero values. This should be changed before the release, so an + application can insist on getting no less than triple-DES + protection.] + +4.2. MIC Sequence Number Encryption + + The sequence numbers are encrypted in the context key (as defined + in [GSSAPI-KRB5] -- this will be either the Kerberos session key or + asubkey provided by the context initiator), using whatever + encryption system is designated by the type of that context key. + The IV is formed from the first N bytes of the SGN_CKSUM field, + where N is the number of bytes needed for the IV. (With all + algorithms described here and in [GSSAPI-KRB5], the checksum is at + least as large as the IV.) + +4.3. Message Layout + + Both MIC and Wrap tokens, as defined in [GSSAPI-KRB5], contain an + checksum field SGN_CKSUM. In [GSSAPI-KRB5], this field was + specified as being 8 bytes long. We now change this size to be + "defined by the checksum algorithm", and retroactively amend the + descriptions of all the checksum algorithms described in + [GSSAPI-KRB5] to explicitly specify 8-byte output. Application + data continues to immediately follow the checksum field in the Wrap + token. + + The revised message descriptions are thus: + + MIC: + + Byte no Name Description + 0..1 TOK_ID Identification field. + 2..3 SGN_ALG Integrity algorithm indicator. + 4..7 Filler Contains ff ff ff ff + 8..15 SND_SEQ Sequence number field. + 16..s+15 SGN_CKSUM Checksum of "to-be-signed data", + calculated according to algorithm + specified in SGN_ALG field. + + Wrap: + + Byte no Name Description + 0..1 TOK_ID Identification field. + Tokens emitted by GSS_Wrap() contain + the hex value 02 01 in this field. + 2..3 SGN_ALG Checksum algorithm indicator. + 4..5 SEAL_ALG Sealing algorithm indicator. + 6..7 Filler Contains ff ff + 8..15 SND_SEQ Encrypted sequence number field. + 16..s+15 SGN_CKSUM Checksum of plaintext padded data, + calculated according to algorithm + specified in SGN_ALG field. + s+16..last Data encrypted or plaintext padded data + + Where "s" indicates the size of the checksum. + + As indicated above in section 2, we define the HMAC SHA1 DES3-KD + checksum algorithm to produce a 20-byte output, so encrypted data + begins at byte 36. + +5. Backwards Compatibility Considerations + + The context initiator should request of the KDC credentials using + session-key cryptosystem types supported by that implementation; if + the only types returned by the KDC are not supported by the + mechanism implementation, it should indicate a failure. This may + seem obvious, but early implementations of both Kerberos and the + GSSAPI Kerberos mechanism supported only DES keys, so the + cryptosystem compatibility question was easy to overlook. + + Under the current mechanism, no negotiation of algorithm types + occurs, so server-side (acceptor) implementations cannot request + that clients not use algorithm types not understood by the server. + However, administration of the server's Kerberos data has to be + done in communication with the KDC, and it is from the KDC that the + client will request credentials. The KDC could therefore be tasked + with limiting session keys for a given service to types actually + supported by the Kerberos and GSSAPI software on the server. + + This does have a drawback for cases where a service principal name + is used both for GSSAPI-based and non-GSSAPI-based communication, + if the GSSAPI implementation does not understand triple-DES but the + Kerberos implementation does. It means that triple-DES session + keys cannot be issued for that service principal, which keeps the + protection of non-GSSAPI services weaker than necessary. However, + in the most recent MIT releases thus far, while triple-DES support + has been present, it has required additional work to enable, so it + should not be in use for many services. + + It would also be possible to have clients attempt to get single-DES + session keys before trying to get triple-DES session keys, and have + the KDC refuse to issue the single-DES keys only for the most + critical of services, for which single-DES protection is considered + inadequate. However, that would eliminate the possibility of + connecting with the more secure cryptosystem to any service that + can be accessed with the weaker cryptosystem. + + We have chosen to go with the former approach, putting the burden + on the KDC administration and gaining the best protection possible + for GSSAPI services, possibly at the cost of protection of + non-GSSAPI Kerberos services running earlier versions of the + software. + [XXX: Actually, we haven't entirely decided and cast it in stone + yet, it's just what I've implemented; it's easy to change.] + +6. Security Considerations + + Various tradeoffs arise regarding the mixing of new and old + software, or GSSAPI-based and non-GSSAPI Kerberos authentication. + They are discussed in section 4. + +7.
