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

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

Affected Packages

media-libs/xine-lib on all architectures
Affected versions < 1.1.10.1
Unaffected versions >= 1.1.10.1

Background

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

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"
