New! Plugin Severity Now Using CVSS v3

The remote Debian host is missing a security-related update.


Pedro Ribeiro discovered a use-after-free in the handling of ImageText requests in the Xorg Xserver, which could result in denial of service or privilege escalation.


Upgrade the xorg-server packages.

For the oldstable distribution (squeeze), this problem has been fixed in version 1.7.7-17.

For the stable distribution (wheezy), this problem has been fixed in version 1.12.4-6+deb7u1.
