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
-------------------------------------------------------------------
1 media-libs/xine-lib < 1.1.10.1 >= 1.1.10.1
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.
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"
