Mandrake Linux Security Advisory : xine-lib (MDKSA-2005:228)

High Nessus Plugin ID 20459


The remote Mandrake Linux host is missing one or more security updates.


Simon Kilvington discovered a vulnerability in FFmpeg libavcodec, which can be exploited by malicious people to cause a DoS (Denial of Service) and potentially to compromise a user's system.

The vulnerability is caused due to a boundary error in the 'avcodec_default_get_buffer()' function of 'utils.c' in libavcodec.
This can be exploited to cause a heap-based buffer overflow when a specially crafted 1x1 '.png' file containing a palette is read.

Xine-lib is built with a private copy of ffmpeg containing this same code. (Corporate Server 2.1 is not vulnerable)

The updated packages have been patched to prevent this problem.


Update the affected packages.
