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-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.
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-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-2017-10971 1 X.org 1 X Server 2025-08-29 N/A
In the X.Org X server before 2017-06-19, a user authenticated to an X Session could crash or execute code in the context of the X Server by exploiting a stack overflow in the endianness conversion of X Events.
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.
CVE-2023-6816 4 Debian, Fedoraproject, Redhat and 1 more 13 Debian Linux, Fedora, Enterprise Linux and 10 more 2025-08-29 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-2024-0408 4 Fedoraproject, Redhat, Tigervnc and 1 more 12 Fedora, Enterprise Linux, Enterprise Linux Desktop and 9 more 2025-08-29 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-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-2023-6377 4 Debian, Redhat, Tigervnc and 1 more 11 Debian Linux, Enterprise Linux, Enterprise Linux Eus and 8 more 2025-08-18 7.8 High
A flaw was found in xorg-server. Querying or changing XKB button actions such as moving from a touchpad to a mouse can result in out-of-bounds memory reads and writes. This may allow local privilege escalation or possible remote code execution in cases where X11 forwarding is involved.
CVE-2024-0229 3 Fedoraproject, Redhat, X.org 13 Fedora, Enterprise Linux, Enterprise Linux Aus and 10 more 2025-08-04 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-2023-6478 4 Debian, Redhat, Tigervnc and 1 more 11 Debian Linux, Enterprise Linux, Enterprise Linux Eus and 8 more 2025-08-04 7.6 High
A flaw was found in xorg-server. A specially crafted request to RRChangeProviderProperty or RRChangeOutputProperty can trigger an integer overflow which may lead to a disclosure of sensitive information.
CVE-2023-5367 4 Debian, Fedoraproject, Redhat and 1 more 17 Debian Linux, Fedora, Enterprise Linux and 14 more 2025-08-04 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-2023-5574 2 Redhat, X.org 2 Enterprise Linux, X Server 2025-07-30 7 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-2022-49737 1 X.org 1 X Server 2025-07-12 7.7 High
In X.Org X server 20.11 through 21.1.16, when a client application uses easystroke for mouse gestures, the main thread modifies various data structures used by the input thread without acquiring a lock, aka a race condition. In particular, AttachDevice in dix/devices.c does not acquire an input lock.
