CVE-2024-0229 3 Fedoraproject, Redhat, X.org 13 Fedora, Enterprise Linux, Enterprise Linux Aus and 10 more 2025-11-06 7.8 High
An out-of-bounds memory access flaw was found in the X.Org server. This issue can be triggered when a device frozen by a sync grab is reattached to a different master device. This issue may lead to an application crash, local privilege escalation (if the server runs with extended privileges), or remote code execution in SSH X11 forwarding environments.
CVE-2023-5367 4 Debian, Fedoraproject, Redhat and 1 more 17 Debian Linux, Fedora, Enterprise Linux and 14 more 2025-11-06 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-2020-14346 3 Canonical, Redhat, X.org 3 Ubuntu Linux, Enterprise Linux, X Server 2025-08-29 7.8 High
A flaw was found in xorg-x11-server before 1.20.9. An integer underflow in the X input extension protocol decoding in the X server may lead to arbitrary access of memory contents. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
CVE-2014-8102 3 Debian, Redhat, X.org 4 Debian Linux, Enterprise Linux, X11 and 1 more 2025-08-29 N/A
The SProcXFixesSelectSelectionInput function in the XFixes extension in X.Org X Window System (aka X11 or X) X11R6.8.0 and X.Org Server (aka xserver and xorg-server) before 1.16.3 allows remote authenticated users to cause a denial of service (out-of-bounds read or write) or possibly execute arbitrary code via a crafted length value.
CVE-2017-2624 2 Debian, X.org 2 Debian Linux, X Server 2025-08-29 N/A
It was found that xorg-x11-server before 1.19.0 including uses memcmp() to check the received MIT cookie against a series of valid cookies. If the cookie is correct, it is allowed to attach to the Xorg session. Since most memcmp() implementations return after an invalid byte is seen, this causes a time difference between a valid and invalid byte, which could allow an efficient brute force attack.
