Gentoo Linux Security Advisory

Title: MPlayer: Multiple integer overflows (GLSA 200603-03)
Severity: normal
Exploitable: remote
Date: March 04, 2006
Updated: June 21, 2006
Bug(s): #115760, #122029
ID: 200603-03

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: media-video/mplayer
Vulnerable: < 1.0.20060217
Unaffected: >= 1.0.20060217
Unaffected: >= 1.0_pre8
Architectures: All supported architectures


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:
Code:
# emerge --sync
    # emerge --ask --oneshot --verbose ">=media-video/mplayer-1.0.20060217"
