USN-3353-1 fixed a vulnerability in Heimdal. This update provides
the corresponding update for Samba.
Jeffrey Altman, Viktor Dukhovni, and Nicolas Williams discovered
that Samba clients incorrectly trusted unauthenticated portions of
Kerberos tickets. A remote attacker could use this to impersonate
trusted network servers or perform other attacks.
