20 April 2009

xine-lib vulnerabilities

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

  • Ubuntu 8.10
  • Ubuntu 8.04 LTS
  • Ubuntu 6.06 LTS

Software Description

  • xine-lib

Details

It was discovered that the QT demuxer in xine-lib did not correctly handle a large count value in an STTS atom, resulting in a heap-based buffer overflow. If a user or automated system were tricked into opening a specially crafted MOV file, an attacker could execute arbitrary code as the user invoking the program. (CVE-2009-1274)

USN-746-1 provided updated xine-lib packages to fix multiple security vulnerabilities. The security patch to fix CVE-2009-0698 was incomplete. This update corrects the problem.

Original advisory 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)

Update instructions

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

Ubuntu 8.10
libxine1 - 1.1.15-0ubuntu3.3
Ubuntu 8.04 LTS
libxine1 - 1.1.11.1-1ubuntu3.4
