Mandrake Linux Security Advisory : ffmpeg (MDKSA-2005:231)

high Nessus Plugin ID 20462

Synopsis

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

Description

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.

The updated packages have been patched to prevent this problem.

Solution

Update the affected packages.
