CVE-2023-5574 2 Redhat, X.org 2 Enterprise Linux, X Server 2024-11-21 N/A 7.0 HIGH
A use-after-free flaw was found in xorg-x11-server-Xvfb. This issue occurs in Xvfb with 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 a screen 1 to a screen 0, a use-after-free issue may be triggered during shutdown or reset of the Xvfb server, allowing for possible escalation of privileges or denial of service.
CVE-2023-5380 4 Debian, Fedoraproject, Redhat and 1 more 5 Debian Linux, Fedora, Enterprise Linux and 2 more 2024-11-21 N/A 4.7 MEDIUM
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.
CVE-2023-5367 4 Debian, Fedoraproject, Redhat and 1 more 12 Debian Linux, Fedora, Enterprise Linux and 9 more 2024-11-21 N/A 7.8 HIGH
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.
CVE-2022-46344 4 Debian, Fedoraproject, Redhat and 1 more 4 Debian Linux, Fedora, Enterprise Linux and 1 more 2024-11-21 N/A 8.8 HIGH
A vulnerability was found in X.Org. This security flaw occurs because the handler for the XIChangeProperty request has a length-validation issues, resulting in out-of-bounds memory reads and potential information disclosure. This issue can lead to local privileges elevation on systems where the X server is running privileged and remote code execution for ssh X forwarding sessions.
CVE-2022-3553 1 X.org 1 X Server 2024-11-21 N/A 3.5 LOW
A vulnerability, which was classified as problematic, was found in X.org Server. This affects an unknown part of the file hw/xquartz/X11Controller.m of the component xquartz. The manipulation leads to denial of service. It is recommended to apply a patch to fix this issue. The identifier VDB-211053 was assigned to this vulnerability.
CVE-2022-3551 3 Debian, Fedoraproject, X.org 3 Debian Linux, Fedora, X Server 2024-11-21 N/A 3.5 LOW
A vulnerability, which was classified as problematic, has been found in X.org Server. Affected by this issue is the function ProcXkbGetKbdByName of the file xkb/xkb.c. The manipulation leads to memory leak. It is recommended to apply a patch to fix this issue. The identifier of this vulnerability is VDB-211052.
CVE-2022-3550 3 Debian, Fedoraproject, X.org 3 Debian Linux, Fedora, X Server 2024-11-21 N/A 5.5 MEDIUM
A vulnerability classified as critical was found in X.org Server. Affected by this vulnerability is the function _GetCountedString of the file xkb/xkb.c. The manipulation leads to buffer overflow. It is recommended to apply a patch to fix this issue. The associated identifier of this vulnerability is VDB-211051.

CVE-2019-17624 1 X.org 1 X Server 2024-11-21 4.6 MEDIUM 7.8 HIGH
"" In X.Org X Server 1.20.4, there is a stack-based buffer overflow in the function XQueryKeymap. For example, by sending ct.c_char 1000 times, an attacker can cause a denial of service (application crash) or possibly have unspecified other impact. Note: It is disputed if the X.Org X Server is involved or if there is a stack overflow.
