Severity:	normal
Title:	xine-lib: Buffer overflow vulnerability
Date:	04/26/2006
Bugs:	#128838
ID:	200604-16

Synopsis

xine-lib contains a buffer overflow vulnerability which may lead to the execution of arbitrary code.

Background

xine-lib is the xine core engine. xine is a free multimedia player. It plays CDs, DVDs, and VCDs, and can also decode other common multimedia formats.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
media-libs/xine-lib	< 1.1.2_pre20060328-r1	>= 1.1.2_pre20060328-r1	All supported architectures

Description

Federico L. Bossi Bonin discovered that when handling MPEG streams xine-lib fails to make a proper boundary check of the input data supplied by the user before copying it to an insufficiently sized memory buffer.

Impact

A remote attacker could entice a user to play a specially-crafted MPEG file, resulting in the execution of arbitrary code with the permissions of the user running the application.

Workaround

There is no known workaround at this time.

Resolution

All xine-lib users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=media-libs/xine-lib-1.1.2_pre20060328-r1"
