| 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-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. | ||||

| 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-2017-13723 | 2 Debian, X.org | 2 Debian Linux, X Server | 2025-08-29 | N/A |
| In X.Org Server (aka xserver and xorg-server) before 1.19.4, a local attacker authenticated to the X server could overflow a global buffer, causing crashes of the X server or potentially other problems by injecting large or malformed XKB related atoms and accessing them via xkbcomp. | ||||
| CVE-2022-4283 | 4 Debian, Fedoraproject, Redhat and 1 more | 4 Debian Linux, Fedora, Enterprise Linux and 1 more | 2025-08-29 | 7.8 High |
| A vulnerability was found in X.Org. This security flaw occurs because the XkbCopyNames function left a dangling pointer to freed memory, resulting in out-of-bounds memory access on subsequent XkbGetKbdByName requests.. 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-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. | ||||
| 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-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-2017-12176 | 2 Debian, X.org | 2 Debian Linux, X Server | 2025-08-29 | N/A |
| xorg-x11-server before 1.19.5 was missing extra length validation in ProcEstablishConnection function allowing malicious X client to cause X server to crash or possibly execute arbitrary code. | ||||
| 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-2017-13721 | 2 Debian, X.org | 2 Debian Linux, X Server | 2025-08-29 | N/A |
| In X.Org Server (aka xserver and xorg-server) before 1.19.4, an attacker authenticated to an X server with the X shared memory extension enabled can cause aborts of the X server or replace shared memory segments of other X clients in the same session. | ||||

| Multiple integer overflows in X.Org X Window System (aka X11 or X) X11R1 and X.Org Server (aka xserver and xorg-server) before 1.16.3 allow remote authenticated users to cause a denial of service (crash) or possibly execute arbitrary code via a crafted request to the (1) ProcPutImage, (2) GetHosts, (3) RegionSizeof, or (4) REQUEST_FIXED_SIZE function, which triggers an out-of-bounds read or write. | ||||
| CVE-2014-8093 | 2 Redhat, X.org | 4 Enterprise Linux, X11, X Server and 1 more | 2025-08-29 | N/A |
| Multiple integer overflows in the GLX extension in XFree86 4.0, X.Org X Window System (aka X11 or X) X11R6.7, and X.Org Server (aka xserver and xorg-server) before 1.16.3 allow remote authenticated users to cause a denial of service (crash) or possibly execute arbitrary code via a crafted request to the (1) __glXDisp_ReadPixels, (2) __glXDispSwap_ReadPixels, (3) __glXDisp_GetTexImage, (4) __glXDispSwap_GetTexImage, (5) GetSeparableFilter, (6) GetConvolutionFilter, (7) GetHistogram, (8) GetMinmax, (9) GetColorTable, (10) __glXGetAnswerBuffer, (11) __GLX_GET_ANSWER_BUFFER, (12) __glXMap1dReqSize, (13) __glXMap1fReqSize, (14) Map2Size, (15) __glXMap2dReqSize, (16) __glXMap2fReqSize, (17) __glXImageSize, or (18) __glXSeparableFilter2DReqSize function, which triggers an out-of-bounds read or write. | ||||
| CVE-2014-8095 | 3 Debian, Redhat, X.org | 4 Debian Linux, Enterprise Linux, X11 and 1 more | 2025-08-29 | N/A |
| The XInput extension in X.Org X Window System (aka X11 or X) X11R4 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) SProcXChangeDeviceControl, (2) ProcXChangeDeviceControl, (3) ProcXChangeFeedbackControl, (4) ProcXSendExtensionEvent, (5) SProcXIAllowEvents, (6) SProcXIChangeCursor, (7) ProcXIChangeHierarchy, (8) SProcXIGetClientPointer, (9) SProcXIGrabDevice, (10) SProcXIUngrabDevice, (11) ProcXIUngrabDevice, (12) SProcXIPassiveGrabDevice, (13) ProcXIPassiveGrabDevice, (14) SProcXIPassiveUngrabDevice, (15) ProcXIPassiveUngrabDevice, (16) SProcXListDeviceProperties, (17) SProcXDeleteDeviceProperty, (18) SProcXIListProperties, (19) SProcXIDeleteProperty, (20) SProcXIGetProperty, (21) SProcXIQueryDevice, (22) SProcXIQueryPointer, (23) SProcXISelectEvents, (24) SProcXISetClientPointer, (25) SProcXISetFocus, (26) SProcXIGetFocus, or (27) SProcXIWarpPointer function. | ||||
