An Attacker Could Take Over Impacted Systems With 3 Commands or Less

A security researcher has discovered a highly critical flaw in X.Org Server package that impacts OpenBSD and most Linux distributions, including Debian, Ubuntu, CentOS, Red Hat, and Fedora.

The flaw, tracked as CVE-2018-14665, was introduced in X.Org server 1.19.0 package that remained undetected for almost two years and could have been exploited by a local attacker on the terminal or via SSH to elevate their privileges on a target system.

The X.Org foundation has now released X.Org Server version 1.20.3 with security patches to address the issue. While, popular distributions like OpenBSD, Debian, Ubuntu, CentOS, Red Hat, and Fedora have published their advisories to confirm the issue and working on the patch updates.

All Linux vendors are recommending all customers update their operating systems as quickly as possible, all patches are available from OS vendors to address the vulnerability and are now available in Syxsense for immediate deployment.
