[GLSA-200404-20] Multiple vulnerabilities in xine |
||
Multiple vulnerabilities in xine Detailed Explanation for this Vulnerability Assessment The remote host is affected by the vulnerability described in GLSA-200404-20 (Multiple vulnerabilities in xine) Several vulnerabilities were found in xine-ui and xine-lib. By opening a malicious MRL in any xine-lib based media player, a possible hacker 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, a possible hacker 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 permiting a local attacker to use a symlink attack. Impact These three vulnerabilities may alow a possible hacker 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 rights 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. References: http://xinehq.de/index.php/security http://nettwerked.mg2.org/advisories/xinebug Solution: All users of xine-ui or another xine-based player should upgrade to the latest stable versions: # 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" Network Security Threat Level: Medium Networks Security ID: Vulnerability Assessment Copyright: (C) 2005 Michel Arboi |
