| CVE-2023-1393 | 3 Fedoraproject, Redhat, X.org | 7 Fedora, Enterprise Linux, Rhel Aus and 4 more | 2025-08-29 | 7.8 High |
| A flaw was found in X.Org Server Overlay Window. A Use-After-Free may lead to local privilege escalation. If a client explicitly destroys the compositor overlay window (aka COW), the Xserver would leave a dangling pointer to that window in the CompScreen structure, which will trigger a use-after-free later. | ||||
| CVE-2017-12187 | 2 Debian, X.org | 2 Debian Linux, X Server | 2025-08-29 | N/A |
| xorg-x11-server before 1.19.5 was missing length validation in RENDER extension allowing malicious X client to cause X server to crash or possibly execute arbitrary code. | ||||
| CVE-2017-12179 | 2 Debian, X.org | 2 Debian Linux, X Server | 2025-08-29 | N/A |
| xorg-x11-server before 1.19.5 was vulnerable to integer overflow in (S)ProcXIBarrierReleasePointer functions allowing malicious X client to cause X server to crash or possibly execute arbitrary code. | ||||
| CVE-2017-12184 | 2 Debian, X.org | 2 Debian Linux, X Server | 2025-08-29 | N/A |
| xorg-x11-server before 1.19.5 was missing length validation in XINERAMA extension allowing malicious X client to cause X server to crash or possibly execute arbitrary code. | ||||
| 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. | ||||
| CVE-2017-12185 | 2 Debian, X.org | 2 Debian Linux, X Server | 2025-08-29 | N/A |
| xorg-x11-server before 1.19.5 was missing length validation in MIT-SCREEN-SAVER extension allowing malicious X client to cause X server to crash or possibly execute arbitrary code. | ||||
| CVE-2022-2319 | 2 Redhat, X.org | 2 Enterprise Linux, X Server | 2025-08-29 | 7.8 High |
| A flaw was found in the Xorg-x11-server. An out-of-bounds access issue can occur in the ProcXkbSetGeometry function due to improper validation of the request length. | ||||
| CVE-2014-8099 | 2 Redhat, X.org | 4 Enterprise Linux, X11, X Server and 1 more | 2025-08-29 | N/A |
| The XVideo extension in XFree86 4.0.0, X.Org X Window System (aka X11 or X) X11R6.7, 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 or index value to the (1) SProcXvQueryExtension, (2) SProcXvQueryAdaptors, (3) SProcXvQueryEncodings, (4) SProcXvGrabPort, (5) SProcXvUngrabPort, (6) SProcXvPutVideo, (7) SProcXvPutStill, (8) SProcXvGetVideo, (9) SProcXvGetStill, (10) SProcXvPutImage, (11) SProcXvShmPutImage, (12) SProcXvSelectVideoNotify, (13) SProcXvSelectPortNotify, (14) SProcXvStopVideo, (15) SProcXvSetPortAttribute, (16) SProcXvGetPortAttribute, (17) SProcXvQueryBestSize, (18) SProcXvQueryPortAttributes, (19) SProcXvQueryImageAttributes, or (20) SProcXvListImageFormats function. | ||||
| CVE-2020-14362 | 3 Canonical, Redhat, X.org | 3 Ubuntu Linux, Enterprise Linux, X Server | 2025-08-29 | 7.8 High |
| A flaw was found in X.Org Server before xorg-x11-server 1.20.9. An Integer underflow leading to heap-buffer overflow may lead to a privilege escalation vulnerability. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. | ||||
| CVE-2015-3164 | 2 Opensuse, X.org | 3 Opensuse, X Server, Xorg-server | 2025-08-29 | N/A |
| The authentication setup in XWayland 1.16.x and 1.17.x before 1.17.2 starts the server in non-authenticating mode, which allows local users to read from or send information to arbitrary X11 clients via vectors involving a UNIX socket. | ||||
| CVE-2017-12177 | 2 Debian, X.org | 2 Debian Linux, X Server | 2025-08-29 | N/A |
| xorg-x11-server before 1.19.5 was vulnerable to integer overflow in ProcDbeGetVisualInfo function allowing malicious X client to cause X server to crash or possibly execute arbitrary code. | ||||
| CVE-2017-10972 | 1 X.org | 1 X Server | 2025-08-29 | N/A |
| Uninitialized data in endianness conversion in the XEvent handling of the X.Org X Server before 2017-06-19 allowed authenticated malicious users to access potentially privileged data from the X server. | ||||
| CVE-2017-12181 | 2 Debian, X.org | 2 Debian Linux, X Server | 2025-08-29 | N/A |
| xorg-x11-server before 1.19.5 was missing length validation in XFree86 DGA extension allowing malicious X client to cause X server to crash or possibly execute arbitrary code. | ||||
| CVE-2022-2320 | 2 Redhat, X.org | 2 Enterprise Linux, X Server | 2025-08-29 | 7.8 High |
| A flaw was found in the Xorg-x11-server. The specific flaw exists within the handling of ProcXkbSetDeviceInfo requests. The issue results from the lack of proper validation of user-supplied data, which can result in a memory access past the end of an allocated buffer. This flaw allows an attacker to escalate privileges and execute arbitrary code in the context of root. | ||||
| CVE-2018-14665 | 4 Canonical, Debian, Redhat and 1 more | 10 Ubuntu Linux, Debian Linux, Enterprise Linux and 7 more | 2025-08-29 | N/A |
| A flaw was found in xorg-x11-server before 1.20.3. An incorrect permission check for -modulepath and -logfile options when starting Xorg. X server allows unprivileged users with the ability to log in to the system via physical console to escalate their privileges and run arbitrary code under root privileges. | ||||
| CVE-2020-14361 | 3 Canonical, Redhat, X.org | 3 Ubuntu Linux, Enterprise Linux, X Server | 2025-08-29 | 7.8 High |
| A flaw was found in X.Org Server before xorg-x11-server 1.20.9. An Integer underflow leading to heap-buffer overflow may lead to a privilege escalation vulnerability. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. | ||||
| CVE-2017-12186 | 2 Debian, X.org | 2 Debian Linux, X Server | 2025-08-29 | N/A |

| CVE-2017-12183 | 2 Debian, X.org | 2 Debian Linux, X Server | 2025-08-29 | N/A |
| xorg-x11-server before 1.19.5 was missing length validation in XFIXES extension allowing malicious X client to cause X server to crash or possibly execute arbitrary code. | ||||
| CVE-2015-3418 | 2 Redhat, X.org | 2 Enterprise Linux, X Server | 2025-08-29 | N/A |
| The ProcPutImage function in dix/dispatch.c in X.Org Server (aka xserver and xorg-server) before 1.16.4 allows attackers to cause a denial of service (divide-by-zero and crash) via a zero-height PutImage request. | ||||
| CVE-2020-14347 | 4 Canonical, Debian, Redhat and 1 more | 4 Ubuntu Linux, Debian Linux, Enterprise Linux and 1 more | 2025-08-29 | 5.5 Medium |
| A flaw was found in the way xserver memory was not properly initialized. This could leak parts of server memory to the X client. In cases where Xorg server runs with elevated privileges, this could result in possible ASLR bypass. Xorg-server before version 1.20.9 is vulnerable. | ||||
