| CVE-2020-14362 | 3 Canonical, Redhat, X.org | 3 Ubuntu Linux, Enterprise Linux, X Server | 2025-08-29 | 4.6 MEDIUM | 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-2014-8092 | 1 X.org | 2 X11, X Server | 2025-08-29 | 6.5 MEDIUM | N/A |
| 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-2014-8096 | 2 Debian, X.org | 3 Debian Linux, X11, X Server | 2025-08-29 | 6.5 MEDIUM | N/A |
| The SProcXCMiscGetXIDList function in the XC-MISC extension in X.Org X Window System (aka X11 or X) X11R6.0 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 or index value. | |||||
| CVE-2024-0408 | 4 Fedoraproject, Redhat, Tigervnc and 1 more | 12 Fedora, Enterprise Linux, Enterprise Linux Desktop and 9 more | 2025-08-29 | N/A | 5.5 MEDIUM |
| A flaw was found in the X.Org server. The GLX PBuffer code does not call the XACE hook when creating the buffer, leaving it unlabeled. When the client issues another request to access that resource (as with a GetGeometry) or when it creates another resource that needs to access that buffer, such as a GC, the XSELINUX code will try to use an object that was never labeled and crash because the SID is NULL. | |||||
| CVE-2017-13721 | 2 Debian, X.org | 2 Debian Linux, X Server | 2025-08-29 | 1.9 LOW | 4.7 MEDIUM |
| 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. | |||||
| CVE-2017-12178 | 2 Debian, X.org | 2 Debian Linux, X Server | 2025-08-29 | 7.5 HIGH | 9.8 CRITICAL |
| xorg-x11-server before 1.19.5 had wrong extra length check in ProcXIChangeHierarchy function allowing malicious X client to cause X server to crash or possibly execute arbitrary code. | |||||
| CVE-2022-4283 | 4 Debian, Fedoraproject, Redhat and 1 more | 4 Debian Linux, Fedora, Enterprise Linux and 1 more | 2025-08-29 | N/A | 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-2014-8095 | 2 Debian, X.org | 3 Debian Linux, X11, X Server | 2025-08-29 | 6.5 MEDIUM | 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. | |||||
| CVE-2017-2624 | 2 Debian, X.org | 2 Debian Linux, X Server | 2025-08-29 | 1.9 LOW | 5.9 MEDIUM |
| 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-2022-2320 | 1 X.org | 1 X Server | 2025-08-29 | N/A | 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-2014-8094 | 3 Debian, Oracle, X.org | 3 Debian Linux, Solaris, X Server | 2025-08-29 | 6.5 MEDIUM | N/A |
| Integer overflow in the ProcDRI2GetBuffers function in the DRI2 extension in X.Org Server (aka xserver and xorg-server) 1.7.0 through 1.16.x before 1.16.3 allows remote authenticated users to cause a denial of service (crash) or possibly execute arbitrary code via a crafted request, which triggers an out-of-bounds read or write. | |||||
| CVE-2023-6816 | 4 Debian, Fedoraproject, Redhat and 1 more | 7 Debian Linux, Fedora, Enterprise Linux Desktop and 4 more | 2025-08-29 | N/A | 9.8 CRITICAL |
| A flaw was found in X.Org server. Both DeviceFocusEvent and the XIQueryPointer reply contain a bit for each logical button currently down. Buttons can be arbitrarily mapped to any value up to 255, but the X.Org Server was only allocating space for the device's particular number of buttons, leading to a heap overflow if a bigger value was used. | |||||
| CVE-2014-8099 | 1 X.org | 3 X11, X Server, Xfree86 | 2025-08-29 | 6.5 MEDIUM | 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-2017-13723 | 2 Debian, X.org | 2 Debian Linux, X Server | 2025-08-29 | 4.6 MEDIUM | 7.8 HIGH |
| 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. | |||||
