Synopsis
========
Two vulnerabilities have been found in MPlayer which could lead to the
remote execution of arbitrary code.
Background
==========
MPlayer is a media player capable of handling multiple multimedia file
formats.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 media-video/mplayer < 1.0_pre6-r4 >= 1.0_pre6-r4
Description
===========
Heap overflows have been found in the code handling RealMedia RTSP and
Microsoft Media Services streams over TCP (MMST).
Impact
======
By setting up a malicious server and enticing a user to use its
streaming data, a remote attacker could possibly execute arbitrary code
on the client computer 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:
# emerge --sync
# emerge --ask --oneshot --verbose ">=media-video/mplayer-1.0_pre6-r4"
