+Subject: [PATCH 1/1] mk: Change umask from 002 to 022 in the CreateDir macro.
+
+The build system has a macro called CreateDir that does more or less
+what you'd expect. But before it creates the directory given to it, it
+sets the umask to 002. This can be a vulnerability, since we don't
+know who the end user will be building the software as; there may be
+untrusted people in his default group. In that case, one of those
+people can overwrite the scripts in the directory created by CreateDir
+before the user executes them.
+
+There is a kernel-level workaround for these types of vulnerabilities
+in the Grsecurity project called Trusted Path Execution (TPE). When
+enabled, users are not allowed to execute files in directories not
+owned by themselves or root. When that restriction is enabled, omniORB
+fails to build (due to the aforementioned umask).
+
+This commit changes the umask to 022 in CreateDir. This should not
+cause any problems (ha ha), and is safer than the previous umask of
+002. It also fixes the build on systems where TPE is enabled.
