[GLSA-200404-20] Multiple vulnerabilities in xine
Vulnerability Assessment Summary
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.

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"
