FreeBSD : krb5 -- KDC NULL pointer dereference in TGS handling (6c7d9a35-2608-11e1-89b4-001ec9578670)

Medium Nessus Plugin ID 57293


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


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.


Update the affected package.
