[GLSA]

Gentoo Linux Security Advisory

Title: xine-lib: User-assisted execution of arbitrary code (GLSA 200802-12)
Severity: normal
Exploitable: remote
Date: February 26, 2008
Updated: March 03, 2008
Bug(s): #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: media-libs/xine-lib
Vulnerable: < 1.1.10.1
Unaffected: >= 1.1.10.1
Architectures: 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:
