This update incorporates the upstream patches to fix CVE-2009-3295, a remotely- triggerable crash in the KDC. This update also addresses some packaging bugs, makes changes to the PAM support in ksu, and backports a change which allows GSSAPI acceptors to store delegated Kerberos credentials in credential caches when clients use SPNEGO.
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.
