Description

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, 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 allow 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.
