This update incorporates fixes for a stack overflow in the rpcsec_gss implementation in libgssrpc (CVE-2007-3999) and a potential write through an uninitialized pointer in kadmind (CVE-2007-4000).

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.
