Date:01/12/2009
Bugs: #231836, #239130, #251017
ID:200901-07

Synopsis

Multiple vulnerabilities in MPlayer may lead to the execution of arbitrary code or a Denial of Service.

Background

MPlayer is a media player including support for a wide range of audio and video formats.

Affected packages

Package Vulnerable Unaffected Architecture(s)
media-video/mplayer < 1.0_rc2_p28058-r1 >= 1.0_rc2_p28058-r1 All supported architectures

Description

Multiple vulnerabilities have been reported in MPlayer:

  • A stack-based buffer overflow was found in the str_read_packet() function in libavformat/psxstr.c when processing crafted STR files that interleave audio and video sectors (CVE-2008-3162).
  • Felipe Andres Manzano reported multiple integer underflows in the demux_real_fill_buffer() function in demux_real.c when processing crafted Real Media files that cause the stream_read() function to read or write arbitrary memory (CVE-2008-3827).
  • Tobias Klein reported a stack-based buffer overflow in the demux_open_vqf() function in libmpdemux/demux_vqf.c when processing malformed TwinVQ files (CVE-2008-5616).

Impact

A remote attacker could entice a user to open a specially crafted STR, Real Media, or TwinVQ file to execute arbitrary code or cause a Denial of Service.

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_rc2_p28058-r1 "
