Ubuntu Security Notice USN-315-1

12th July, 2006

libmms, xine-lib vulnerabilities

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

• Ubuntu 6.06 LTS
• Ubuntu 5.10
• Ubuntu 5.04

Details

Matthias Hopf discovered several buffer overflows in libmms. By
tricking a user into opening a specially crafted remote multimedia
stream with an application using libmms, a remote attacker could
exploit this to execute arbitrary code with the user's privileges.

The Xine library contains an embedded copy of libmms, and thus needs
the same security update.

Update instructions

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

Ubuntu 6.06 LTS:

libxine-main1 1.1.1+ubuntu2-7.2

Ubuntu 5.10:

libmms0 0.1-0ubuntu1.2

libxine1c2 1.0.1-1ubuntu10.4

Ubuntu 5.04:

libxine1 1.0-1ubuntu3.8

To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.

In general, a standard system upgrade is sufficient to effect the
necessary changes.
