high Nessus Plugin ID 140299

Language:

Synopsis

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

Description

Several vulnerabilities have been discovered in the X.Org X server.
Missing input sanitising in X server extensions may result in local privilege escalation if the X server is configured to run with root privileges. In addition an ASLR bypass was fixed.

Solution

Upgrade the xorg-server packages.

For the stable distribution (buster), these problems have been fixed in version 2:1.20.4-1+deb10u1.
