"A flaw was discovered in some bundled Kerberos-aware packages that
would fail to check the results of the setuid() call. This call can
fail in some circumstances on the Linux 2.6 kernel if certain user
limits are reached, which could be abused by a local attacker to get
the applications to continue to run as root, possibly leading to an
elevation of privilege.

Updated packages have been patched to correct this issue."
