We STRONGLY - encourage deploying krb5-1.3.1 in preference to 1.3, especially on - client installations, as the 1.3 release did not conform to the - internet-draft for the revised Kerberos protocol in its encoding of - ETYPE-INFO2. - -* [1683] The non-caching getaddrinfo() API on Mac OS X, which was - causing significant slowdowns under some circumstances, has been - worked around. - -Minor changes in 1.3.1 ----------------------- - -* [1015] gss_accept_sec_context() now passes correct arguments to - TREAD_STR() when reading options beyond the forwarded credential - option. Thanks to Emily Ratliff. - -* [1365] The GSSAPI initiator credentials are no longer cached inside - the GSSAPI library. - -* [1651] A buffer overflow in krb_get_admhst() has been fixed. - -* [1655] krb5_get_permitted_enctypes() and krb5_set_real_time() are - now exported for use by Samba. - -* [1656] gss_init_sec_context() no longer leaks credentials under some - error conditions. - -* [1657] krb_get_lrealm() no longer returns "ATHENA.MIT.EDU" - inappropriately. - -* [1664] The crypto library no longer has bogus dependencies on - com_err. - -* [1665] krb5_init_context() no longer multiply registers error tables - when called more than once, preventing a memory leak. - -* [1666] The GSS_C_NT_* symbols are now exported from gssapi32.dll on - Windows. - -* [1667] ms2mit now imports any tickets with supported enctypes, and - does not import invalid tickets. - -* [1677] krb5_gss_register_acceptor_identity() no longer has an - off-by-one in its memory allocation. - -* [1679] krb5_principal2salt is now exported on all platforms. - -* [1684] The file credentials cache is now supported if USE_CCAPI is - defined, i.e., for KfM and KfW. - -* [1691] Documentation for the obsolete kdc_supported_enctypes config - variable has been removed. - -Notes, Major Changes, and Known Bugs for 1.3 --------------------------------------------- - -* We now install the compile_et program, so other packages can use the - installed com_err library with their own error tables. (If you use - our com_err code, that is; see below.) - -* The header files we install now assume ANSI/ISO C ('89, not '99). - We have stopped testing on SunOS 4, even with gcc. Some of our code - now has C89-based assumptions, like free(NULL) being well defined, - that will probably frustrate any attempts to run this code under SunOS - 4 or other pre-C89 systems. - -* Some new code, bug fixes, and cleanup for IPv6 support. Most of the - code should support IPv6 transparently now. The RPC code (and - therefore the admin system, which is based on it) does not yet - support IPv6. The support for Kerberos 4 may work with IPv6 in very - limited ways, if the address checking is turned off. The FTP client - and server do not have support for the new protocol messages needed - for IPv6 support (RFC 2428). - -* We have upgraded to autoconf 2.52 (or later), and the syntax for - specifying certain configuration options have changed. For example, - autoconf 2.52 configure scripts let you specify command-line options - like "configure CC=/some/path/foo-cc", so we have removed some of - our old options like --with-cc in favor of this approach. - -* The client libraries can now use TCP to connect to the KDC. This - may be necessary when talking to Microsoft KDCs (domain controllers), - if they issue you tickets with lots of PAC data. - -* If you have versions of the com_err or ss installed locally, you can - use the --with-system-et and --with-system-ss configure options to - use them rather than using the versions supplied here. Note that - the interfaces are assumed to be similar to those we supply; in - particular, some older, divergent versions of the com_err library - may not work with the krb5 sources. Many configure-time variables - can be used to help the compiler and linker find the installed - packages; see the build documentation for details. - -* The AES cryptosystem has been implemented. However, support in the - Kerberos GSSAPI mechanism has not been written (or even fully - specified), so it's not fully enabled. See the documentation for - details. - -Major changes listed by ticket ID ---------------------------------- - -* [492] PRNG breakage on 64-bit platforms no longer an issue due to - new PRNG implementation. - -* [523] Client library is now compatible with the RC4-based - cryptosystem used by Windows 2000. - -* [709] krb4 long lifetime support has been implemented. - -* [880] krb5_gss_register_acceptor_identity() implemented (is called - gsskrb5_register_acceptor_identity() by Heimdal). - -* [1087] ftpd no longer requires channel bindings, allowing easier use - of ftp from behind a NAT. - -* [1156, 1209] It is now possible to use the system com_err to build - this release. - -* [1174] TCP support added to client library. - -* [1175] TCP support added to the KDC, but is disabled by default. - -* [1176] autoconf-2.5x is now required by the build system. - -* [1184] It is now possible to use the system Berkeley/Sleepycat DB - library to build this release. - -* [1189, 1251] The KfM krb4 library source base has been merged. - -* [1190] The default KDC master key type is now triple-DES. KDCs - being updated may need their config files updated if they are not - already specifying the master key type. - -* [1190] The default ticket lifetime and default maximum renewable - ticket lifetime have been extended to one day and one week, - respectively. - -* [1191] A new script, k5srvutil, may be used to manipulate keytabs in - ways similar to the krb4 ksrvutil utility. - -* [1281] The "fakeka" program, which emulates the AFS kaserver, has - been integrated. Thanks to Ken Hornstein. - -* [1343] The KDC now defaults to not answering krb4 requests. - -* [1344] Addressless tickets are requested by default now. - -* [1372] There is no longer a need to create a special keytab for - kadmind. The legacy administration daemons "kadmind4" and - "v5passwdd" will still require a keytab, though. - -* [1377, 1442, 1443] The Microsoft set-password protocol has been - implemented. Thanks to Paul Nelson. - -* [1385, 1395, 1410] The krb4 protocol vulnerabilities - [MITKRB5-SA-2003-004] have been worked around. Note that this will - disable krb4 cross-realm functionality, as well as krb4 triple-DES - functionality. Please see doc/krb4-xrealm.txt for details of the - patch. - -* [1393] The xdrmem integer overflows [MITKRB5-SA-2003-003] have - been fixed. - -* [1397] The krb5_principal buffer bounds problems - [MITKRB5-SA-2003-005] have been fixed.
