https://notcve.org/view.php?id=CVE-2023-6377
13 Dec 2023 — A flaw was found in xorg-server. Querying or changing XKB button actions such as moving from a touchpad to a mouse can result in out-of-bounds memory reads and writes. This may allow local privilege escalation or possible remote code execution in cases where X11 forwarding is involved. Se encontró una falla en xorg-server. Consultar o cambiar las acciones de los botones XKB, como pasar de un panel táctil a un mouse, puede provocar lecturas y escrituras de memoria fuera de los límites. • http://www.openwall.com/lists/oss-security/2023/12/13/1 • CWE-125: Out-of-bounds Read •

07 Feb 2023 — A vulnerability was found in X.Org. This issue occurs due to a dangling pointer in DeepCopyPointerClasses that can be exploited by ProcXkbSetDeviceInfo() and ProcXkbGetDeviceInfo() to read and write into freed memory. This can lead to local privilege elevation on systems where the X server runs privileged and remote code execution for ssh X forwarding sessions. This vulnerability allows local attackers to escalate privileges on affected installations of X.Org Server.
