7.5 - USN-746-1

A security issue affects the following Ubuntu releases:

Ubuntu 6.06 LTS Ubuntu 7.10 Ubuntu 8.04 LTS Ubuntu 8.10

This advisory also applies to the corresponding versions of Kubuntu, Edubuntu, and Xubuntu.

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

Ubuntu 6.06 LTS:
libxine-main1 1.1.1+ubuntu2-7.11

Ubuntu 7.10:
libxine1 1.1.7-1ubuntu1.5

Ubuntu 8.04 LTS:
libxine1 1.1.11.1-1ubuntu3.3

Ubuntu 8.10:
libxine1 1.1.15-0ubuntu3.2

After a standard system upgrade you need to restart applications linked against xine-lib, such as Totem-xine and Amarok, to effect the necessary changes.

Details follow:

It was discovered that the 4xm demuxer in xine-lib did not correctly handle a large current_track value in a 4xm file, resulting in an integer overflow. If a user or automated system were tricked into opening a specially crafted 4xm movie file, an attacker could crash xine-lib or possibly execute arbitrary code with the privileges of the user invoking the program. (CVE-2009-0698)

USN-710-1 provided updated xine-lib packages to fix multiple security vulnerabilities. The security patch to fix CVE-2008-5239 introduced a regression causing some media files to be unplayable. This update corrects the problem. We apologize for the inconvenience.

Original advisory details:
It was discovered that the input handlers in xine-lib did not correctly
handle certain error codes, resulting in out-of-bounds reads and heap-
based buffer overflows. If a user or automated system were tricked into
opening a specially crafted file, stream, or URL, an attacker could
execute arbitrary code as the user invoking the program. (CVE-2008-5239)
