http://security.gentoo.org/

Severity:	normal
Title:	MPlayer: Buffer overflow
Date:	02/27/2007
Bugs:	#159727
ID:	200702-11

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	Architecture(s)
media-video/mplayer	< 1.0_rc1-r2	>= 1.0_rc1-r2	All supported architectures

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"
