Debian DSA-4328-1 : xorg-server - security update

medium Nessus Plugin ID 118474
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

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

Description

Narendra Shinde discovered that incorrect command-line parameter validation in the Xorg X server may result in arbitary file overwrite, which can result in privilege escalation.

Solution

Upgrade the xorg-server packages.

For the stable distribution (stretch), this problem has been fixed in version 2:1.19.2-1+deb9u4.
