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-2014-8092 2 Redhat, X.org 3 Enterprise Linux, X11, X Server 2025-08-29 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-2014-8093 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.
