This update incorporates a backported fix to make libgssapi_krb5’s credential import routines work better, which is needed by newer versions of gssproxy, and corrects a packaging error which resulted in the /etc/gss directory not being owned by any packages. Further, it incorporates a fix for a possible remotely-triggered crash in KDCs which are configured to serve multiple realms at once (CVE-2013-1418).
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.
