Synopsis :

The remote FreeBSD host is missing a security-related update.

Description :

The MIT Kerberos Team reports :

In releases krb5-1.9 and later, the KDC can crash due to a NULL
pointer dereference in code that handles TGS (Ticket Granting Service)
requests. The trigger condition is trivial to produce using unmodified
client software, but requires the ability to authenticate as a
principal in the KDC's realm.
