high Nessus Plugin ID 21479

Synopsis

The remote FreeBSD host is missing one or more security-related updates.

Description

Secunia reports :

Simon Kilvington has reported 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.

Solution

Update the affected packages.
