Synopsis:	Important: krb5 security update
Issue date:	2007-09-07
CVE Names:	CVE-2007-4743

The MIT Kerberos Team discovered a problem with the originally published
patch for svc_auth_gss.c (CVE-2007-3999). A remote unauthenticated
attacker who can access kadmind could trigger this flaw and cause kadmind
to crash. On Red Hat Enterprise Linux 5 it is not possible to exploit this
flaw to run arbitrary code as the overflow is blocked by FORTIFY_SOURCE.
