USN-230-2: ffmpeg/xine-lib vulnerability

16 December 2005

xine-lib vulnerability

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

  • Ubuntu 5.10
  • Ubuntu 5.04
  • Ubuntu 4.10

Software Description

Details

USN-230-1 fixed a vulnerability in the ffmpeg library. The Xine library contains a copy of the ffmpeg code, thus it is vulnerable to the same flaw.

For reference, this is the original advisory:

Simon Kilvington discovered a buffer overflow in the avcodec_default_get_buffer() function of the ffmpeg library. By tricking an user into opening a malicious movie which contains specially crafted PNG images, this could be exploited to execute arbitrary code with the user’s privileges.

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