"This update incorporates fixes included in MITKRB5-SA-2008-001 (use of
uninitialized pointer / double-free in the KDC when v4 compatibility
is enabled) and MITKRB5-SA-2008-002 (incorrect handling of
high-numbered descriptors in the RPC library). This update also
incorporates less-critical fixes for a double- free (CVE-2007-5971)
and an incorrect attempt to free non-heap memory (CVE-2007-5901) in
the GSSAPI library.

Note that Tenable Network Security has extracted the preceding
description block directly from the Fedora security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
