which attempted to contact servers using TCP to become wedge. This
update incorporates fixes for a possible remotely-triggered crash in
KDCs which are configured to serve multiple realms at once
(CVE-2013-1418), and another which could occur while the KDC processed
certain requests using referrals (CVE-2013-1417).

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."
