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.
