Ubuntu Security Notice USN-2508-1
February 23, 2015

samba vulnerability
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 14.10
- Ubuntu 14.04 LTS
- Ubuntu 12.04 LTS

Summary:

Samba could be made to run programs as an administrator if it received
specially crafted network traffic.

Software Description:
- samba: SMB/CIFS file, print, and login server for Unix

Details:

Richard van Eeden discovered that the Samba smbd file services incorrectly
handled memory. A remote attacker could use this issue to possibly execute
arbitrary code with root privileges.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 14.10:
  samba                           2:4.1.11+dfsg-1ubuntu2.2

Ubuntu 14.04 LTS:
  samba                           2:4.1.6+dfsg-1ubuntu2.14.04.7

Ubuntu 12.04 LTS:
  samba                           2:3.6.3-2ubuntu2.12

In general, a standard system update will make all the necessary changes.
