Synopsis
========
A buffer overflow was found in MPlayer's RTSP plugin that could lead to
a Denial of Service or arbitrary code execution.
Background
==========
MPlayer is a media player capable of playing multiple media formats.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 media-video/mplayer < 1.0_rc1-r2 >= 1.0_rc1-r2
Description
===========
When checking for matching asm rules in the asmrp.c code, the results
are stored in a fixed-size array without boundary checks which may
allow a buffer overflow.
Impact
======
An attacker can entice a user to connect to a manipulated RTSP server
resulting in a Denial of Service and possibly execution of arbitrary
code.
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_rc1-r2"
