Synopsis

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

2.  Impact Information

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.

3.  Resolution Information

Workaround

There is no known workaround at this time.

Resolution

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

Code Listing 3.1: Resolution

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