Gentoo Linux Security Advisory
Title: Multiple vulnerabilities in xine (GLSA 200404-20)
Severity: normal
Exploitable: remote
Date: April 27, 2004
Updated: May 22, 2006
Bug(s): #45448, #48107, #48108
ID: 200404-20
Synopsis
Several vulnerabilities have been found in xine-ui and xine-lib, potentially allowing an attacker to overwrite files with the rights of the user.
Background
xine is a multimedia player allowing to play back CDs, DVDs, and VCDs and decoding multimedia files like AVI, MOV, WMV, and MP3 from local disk drives, and displays multimedia streamed over the Internet. It is available in Gentoo as a reusable library (xine-lib) with a standard user interface (xine-ui).
Affected Packages
Package: media-video/xine-ui
Vulnerable: <= 0.9.23-r1
Unaffected: >= 0.9.23-r2
Architectures: All supported architectures
Package: media-libs/xine-lib
Vulnerable: <= 1_rc3-r2
Unaffected: >= 1_rc3-r3
Architectures: All supported architectures
Description
Several vulnerabilities were found in xine-ui and xine-lib. By opening a malicious MRL in any xine-lib based media player, an attacker can write arbitrary content to an arbitrary file, only restricted by the permissions of the user running the application. By opening a malicious playlist in the xine-ui media player, an attacker can write arbitrary content to an arbitrary file, only restricted by the permissions of the user running xine-ui. Finally, a temporary file is created in an insecure manner by the xine-check and xine-bugreport scripts, potentially allowing a local attacker to use a symlink attack.
Impact
These three vulnerabilities may alow an attacker to corrupt system files, thus potentially leading to a Denial of Service. It is also theoretically possible, though very unlikely, to use these vulnerabilities to elevate the privileges of the attacker.
Workaround
There is no known workaround at this time. All users are advised to upgrade to the latest available versions of xine-ui and xine-lib.
Resolution
All users of xine-ui or another xine-based player should upgrade to the latest stable versions: Code: | # emerge sync
# emerge -pv ">=media-video/xine-ui-0.9.23-r2"
# emerge ">=media-video/xine-ui-0.9.23-r2"
# emerge -pv ">=media-libs/xine-lib-1_rc3-r3"
# emerge ">=media-libs/xine-lib-1_rc3-r3" |
