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-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-2022-2320 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-2017-12178 2 Debian, X.org 2 Debian Linux, X Server 2025-08-29 N/A
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-2015-0255 3 Opensuse, Redhat, X.org 3 Opensuse, Enterprise Linux, X Server 2025-08-29 N/A
X.Org Server (aka xserver and xorg-server) before 1.16.3 and 1.17.x before 1.17.1 allows remote attackers to obtain sensitive information from process memory or cause a denial of service (crash) via a crafted string length value in a XkbSetGeometry request.
CVE-2014-8091 2 Redhat, X.org 3 Enterprise Linux, X11, X Server 2025-08-29 N/A
X.Org X Window System (aka X11 and X) X11R5 and X.Org Server (aka xserver and xorg-server) before 1.16.3, when using SUN-DES-1 (Secure RPC) authentication credentials, does not check the return value of a malloc call, which allows remote attackers to cause a denial of service (NULL pointer dereference and server crash) via a crafted connection request.
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-2022-46343 4 Debian, Fedoraproject, Redhat and 1 more 4 Debian Linux, Fedora, Enterprise Linux and 1 more 2025-04-22 8.8 High
A vulnerability was found in X.Org. This security flaw occurs because the handler for the ScreenSaverSetAttributes request may write to memory after it has been freed. 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-2022-46342 4 Debian, Fedoraproject, Redhat and 1 more 4 Debian Linux, Fedora, Enterprise Linux and 1 more 2025-04-22 8.8 High

CVE-2022-46341 4 Debian, Fedoraproject, Redhat and 1 more 4 Debian Linux, Fedora, Enterprise Linux and 1 more 2025-04-22 8.8 High
A vulnerability was found in X.Org. This security flaw occurs because the handler for the XIPassiveUngrab request accesses out-of-bounds memory when invoked with a high keycode or button code. 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-2022-46340 4 Debian, Fedoraproject, Redhat and 1 more 4 Debian Linux, Fedora, Enterprise Linux and 1 more 2025-04-22 8.8 High
A vulnerability was found in X.Org. This security flaw occurs becuase the swap handler for the XTestFakeInput request of the XTest extension may corrupt the stack if GenericEvents with lengths larger than 32 bytes are sent through a the XTestFakeInput request. 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. This issue does not affect systems where client and server use the same byte order.
