[GLSA-200603-03] MPlayer: Multiple integer overflows

Vulnerability Assessment Summary
MPlayer: Multiple integer overflows

Detailed Explanation for this Vulnerability Assessment
The remote host is affected by the vulnerability described in GLSA-200603-03
(MPlayer: Multiple integer overflows)

MPlayer makes use of the FFmpeg library, which is vulnerable to a
heap overflow in the avcodec_default_get_buffer() function discovered
by Simon Kilvington (see GLSA 200601-06). Furthermore, AFI Security
Research discovered two integer overflows in ASF file format decoding,
in the new_demux_packet() function from libmpdemux/demuxer.h and the
demux_asf_read_packet() function from libmpdemux/demux_asf.c.

Impact

A possible hacker could craft a malicious media file which, when opened
using MPlayer, would lead to a heap-based buffer overflow. This could
result in the execution of arbitrary code with the permissions of the
user running MPlayer.

Workaround

There is no known workaround at this time.
