| 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-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-2015-3418 | 1 X.org | 1 X Server | 2025-08-29 | 5.0 MEDIUM | 7.5 HIGH |
| 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. | |||||
| CVE-2017-12185 | 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 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-2014-8101 | 1 X.org | 3 X11, X Server, Xfree86 | 2025-08-29 | 6.5 MEDIUM | N/A |
| The RandR extension in XFree86 4.2.0, 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) SProcRRQueryVersion, (2) SProcRRGetScreenInfo, (3) SProcRRSelectInput, or (4) SProcRRConfigureOutputProperty function. | |||||
| CVE-2023-1393 | 2 Fedoraproject, X.org | 2 Fedora, X Server | 2025-08-29 | N/A | 7.8 HIGH |
| A flaw was found in X.Org Server Overlay Window. A Use-After-Free may lead to local privilege escalation. If a client explicitly destroys the compositor overlay window (aka COW), the Xserver would leave a dangling pointer to that window in the CompScreen structure, which will trigger a use-after-free later. | |||||
| 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-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-2020-14347 | 3 Canonical, Debian, X.org | 3 Ubuntu Linux, Debian Linux, X Server | 2025-08-29 | 2.1 LOW | 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-2020-14361 | 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-2015-0255 | 2 Opensuse, X.org | 2 Opensuse, X Server | 2025-08-29 | 6.4 MEDIUM | 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-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-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-2014-8096 | 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-2022-2319 | 1 X.org | 1 X Server | 2025-08-29 | N/A | 7.8 HIGH |
| A flaw was found in the Xorg-x11-server. An out-of-bounds access issue can occur in the ProcXkbSetGeometry function due to improper validation of the request length. | |||||
| CVE-2014-8093 | 1 X.org | 3 X11, X Server, Xfree86 | 2025-08-29 | 6.5 MEDIUM | 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-2014-8097 | 1 X.org | 2 X11, X Server | 2025-08-29 | 6.5 MEDIUM | N/A |
| The DBE extension in X.Org X Window System (aka X11 or X) X11R6.1 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) ProcDbeSwapBuffers or (2) SProcDbeSwapBuffers function. | |||||
| CVE-2020-14346 | 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 xorg-x11-server before 1.20.9. An integer underflow in the X input extension protocol decoding in the X server may lead to arbitrary access of memory contents. 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. | |||||
