Synopsis
========
MPlayer is vulnerable to integer overflows in FFmpeg and ASF decoding
that could potentially result in the execution of arbitrary code.
Background
==========
MPlayer is a media player capable of handling multiple multimedia file
formats.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 media-video/mplayer < 1.0.20060217 >= 1.0.20060217
Description
===========
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
======
An attacker 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.
Resolution
==========
All MPlayer users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=media-video/mplayer-1.0.20060217"
