This update incorporates backported upstream fixes for potential crashes caused by attempts to process malformed GSSAPI messages (CVE-2014-4341, CVE-2014-4342). It also incorporates fexes for a possible double-free (CVE-2014-4343) and a possible NULL pointer dereference (CVE-2014-4344) in GSSAPI clients.
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.
