==========================================================================
Ubuntu Security Notice USN-1423-1
April 13, 2012

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

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

- Ubuntu 11.10
- Ubuntu 11.04
- Ubuntu 10.04 LTS
- Ubuntu 8.04 LTS

Summary:

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

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

Details:

Brian Gorenc discovered that Samba incorrectly calculated array bounds when
handling remote procedure calls (RPC) over the network. A remote,
unauthenticated attacker could exploit this to execute arbitrary code as the
root user. (CVE-2012-1182)

Update instructions:

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

Ubuntu 11.10:
samba 2:3.5.11~dfsg-1ubuntu2.2

Ubuntu 11.04:
samba 2:3.5.8~dfsg-1ubuntu2.4

Ubuntu 10.04 LTS:
samba 2:3.4.7~dfsg-1ubuntu3.9

Ubuntu 8.04 LTS:
samba 3.0.28a-1ubuntu4.18

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