The Federal Office for Security in Information Technology (BSI) published an update on April 29, 2024 to a security hole with several vulnerabilities for X.Org X11 that became known on January 16, 2024. The security vulnerability affects the operating systems Linux and UNIX as well as the open source products CentOS, Debian Linux, Amazon Linux 2, Red Hat Enterprise Linux, Fedora Linux, Ubuntu Linux, SUSE Linux, Oracle Linux, Gentoo Linux, OpenBSD OpenBSD, Open Source X .Org X11 and RESF Rocky Linux.
The latest manufacturer recommendations regarding updates, workarounds and security patches for this vulnerability can be found here: Red Hat Security Advisory RHSA-2024:2169 (As of April 30, 2024). Other useful resources are listed later in this article.
Multiple vulnerabilities for X.Org X11 – Risk: High
Risk level: 4 (high)
CVSS Base Score: 9,8
CVSS Temporal Score: 8,5
Remoteangriff: Ja
The Common Vulnerability Scoring System (CVSS) is used to assess the severity of vulnerabilities in computer systems. The CVSS standard makes it possible to compare potential or actual security vulnerabilities based on various criteria in order to better prioritize countermeasures. The attributes “none”, “low”, “medium”, “high” and “critical” are used to determine the severity levels of a vulnerability. The Base Score evaluates the requirements for an attack (including authentication, complexity, privileges, user interaction) and its consequences. The temporal score also takes changes over time in the danger situation into account. The risk of the vulnerability discussed here is classified as “high” according to the CVSS with a base score of 9.8.

General measures for dealing with IT security gaps
Users of the affected applications should keep them up to date. When security gaps become known, manufacturers are required to fix them as quickly as possible by developing a patch or a workaround. If new security updates are available, install them as soon as possible. For information, consult the sources listed in the next section. These often contain further information about the latest version of the software in question as well as the availability of security patches or information about workarounds. If you have any further questions or uncertainties, please contact your responsible administrator. IT security managers should regularly check the sources mentioned to see whether a new security update is available.
