MPlayer: Buffer overflow — GLSA 200702-11

A buffer overflow was found in MPlayer's RTSP plugin that could lead to a Denial of Service or arbitrary code execution.

Affected Packages

media-video/mplayer on all architectures
Affected versions < 1.0_rc1-r2
Unaffected versions >= 1.0_rc1-r2

Background

MPlayer is a media player capable of playing multiple media formats.

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"
