USN-1966-1: Samba vulnerability
Ubuntu Security Notice USN-1966-1
24th September, 2013
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 13.04
- Ubuntu 12.10
- Ubuntu 12.04 LTS
- Ubuntu 10.04 LTS
Samba could be made to hang if it received specially crafted network traffic.
- samba - SMB/CIFS file, print, and login server for Unix
Jeremy Allison discovered that Samba incorrectly handled certain extended
attribute lists. A remote attacker could use this issue to cause Samba
to hang, resulting in a denial of service.
The problem can be corrected by updating your system to the following package version:
- Ubuntu 13.04:
- samba 2:3.6.9-1ubuntu1.1
- Ubuntu 12.10:
- samba 2:3.6.6-3ubuntu5.2
- Ubuntu 12.04 LTS:
- samba 2:3.6.3-2ubuntu2.8
- Ubuntu 10.04 LTS:
- samba 2:3.4.7~dfsg-1ubuntu3.12
To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
In general, a standard system update will make all the necessary changes.
