Synopsis
=3D=3D=3D=3D=3D=3D=3D=3D

An integer overflow vulnerability in MPlayer may allow for the
execution of arbitrary code.

Background
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

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

Affected packages
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------
  1  media-video/mplayer     < 1.0_rc2_p26753        >=3D 1.0_rc2_p26753


Description
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

k`sOSe reported an integer overflow vulnerability in the
sdpplin_parse() function in the file stream/realrtsp/sdpplin.c, which
can be exploited to overwrite arbitrary memory regions via an overly
large "StreamCount" SDP parameter.

Impact
=3D=3D=3D=3D=3D=3D

A remote attacker could entice a user to open a specially crafted media
file, possibly resulting in the execution of arbitrary code with the
privileges of the user running MPlayer.

Workaround
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

There is no known workaround at this time.

Resolution
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

All MPlayer users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose
">=3Dmedia-video/mplayer-1.0_rc2_p26753"
