GLSA 200802-12: xine-lib: User-assisted execution of arbitrary code

http://security.gentoo.org/

Severity:	normal
Title:	xine-lib: User-assisted execution of arbitrary code
Date:	02/26/2008
Bugs:	#209106, #208100
ID:	200802-12

Synopsis

xine-lib is vulnerable to multiple buffer overflows when processing FLAC and ASF streams.

Background

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

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
media-libs/xine-lib	< 1.1.10.1	>= 1.1.10.1	All supported architectures

Description

Damian Frizza and Alfredo Ortega (Core Security Technologies) discovered a stack-based buffer overflow within the open_flac_file() function in the file demux_flac.c when parsing tags within a FLAC file (CVE-2008-0486). A buffer overflow when parsing ASF headers, which is similar to CVE-2006-1664, has also been discovered (CVE-2008-1110).

Impact

A remote attacker could entice a user to play specially crafted FLAC or ASF video streams 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 should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=media-libs/xine-lib-1.1.10.1"
