16 Mar 2025 — In X.Org X server 20.11 through 21.1.16, when a client application uses easystroke for mouse gestures, the main thread modifies various data structures used by the input thread without acquiring a lock, aka a race condition. In particular, AttachDevice in dix/devices.c does not acquire an input lock. • https://bugs.debian.org/cgi-bin/bugreport.cgi?att=1;bug=1081338;filename=dix-Hold-input-lock-for-AttachDevice.patch;msg=5 • CWE-413: Improper Resource Locking •

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 •

25 Oct 2023 — A use-after-free flaw was found in the xorg-x11-server. An X server crash may occur in a very specific and legacy configuration (a multi-screen setup with multiple protocol screens, also known as Zaphod mode) if the pointer is warped from within a window on one screen to the root window of the other screen and if the original window is destroyed followed by another window being destroyed.

25 Oct 2023 — A out-of-bounds write flaw was found in the xorg-x11-server. This issue occurs due to an incorrect calculation of a buffer offset when copying data stored in the heap in the XIChangeDeviceProperty function in Xi/xiproperty.c and in RRChangeOutputProperty function in randr/rrproperty.c, allowing for possible escalation of privileges or denial of service.

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. An attacker must first obtain the abilit... • https://bugzilla.redhat.com/show_bug.cgi?id=2165995 • CWE-416: Use After Free •
