xine-lib vulnerability

Releases

Packages

Details

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)

Update instructions

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

Ubuntu 8.10
Ubuntu 8.04
Ubuntu 7.10
Ubuntu 6.06

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.
