Severity:	normal
Title:	xine-lib: Heap-based buffer overflow
Date:	04/14/2007
Bugs:	#170208
ID:	200704-09

Synopsis

xine-lib is vulnerable to a heap-based buffer overflow.

Background

xine-lib is the core library package for the xine media player.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
media-libs/xine-lib	< 1.1.4-r2	>= 1.1.4-r2	x86

Description

xine-lib does not check boundaries on data being read into buffers from DMO video files in code that is shared with MPlayer (DMO_VideoDecoder.c).

Impact

An attacker could entice a user to play a specially crafted DMO video file with a player using xine-lib, potentially resulting in the execution of arbitrary code with the privileges of the user running the player.

Workaround

There is no known workaround at this time.

Resolution

All xine-lib users on the x86 platform should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=media-libs/xine-lib-1.1.4-r2"
