"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.

Mplayer is built with a private copy of ffmpeg containing this same
code.

The updated packages have been patched to prevent this problem."
