GLSA-200603-03 : MPlayer: Multiple integer overflows

This script is Copyright (C) 2006-2014 Tenable Network Security, Inc.


Synopsis :

The remote Gentoo host is missing one or more security-related
patches.

Description :

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 :

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.

Solution :

All MPlayer users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=media-video/mplayer-1.0.20060217'

Risk factor :

High / CVSS Base Score : 7.5
