(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, 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.

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"
Risk factor : Medium
