24 July 2017
Samba could allow unintended access to network services.
Releases
Packages
- samba - SMB/CIFS file, print, and login server for Unix
Details
USN-3353-1 fixed a vulnerability in Heimdal. This update provides the corresponding update for Samba.
Original advisory details:
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 services or perform other attacks.
Update instructions
The problem can be corrected by updating your system to the following package versions:
Ubuntu 12.04
In general, a standard system update will make all the necessary changes.
