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: media-video/mplayer
Vulnerable: < 1.0_rc2_p28058-r1
Unaffected: >= 1.0_rc2_p28058-r1
Architectures: 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:
