| X.Org Server (aka xserver and xorg-server) 1.15.0 through 1.16.x 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) sproc_dri3_query_version, (2) sproc_dri3_open, (3) sproc_dri3_pixmap_from_buffer, (4) sproc_dri3_buffer_from_pixmap, (5) sproc_dri3_fence_from_fd, (6) sproc_dri3_fd_from_fence, (7) proc_present_query_capabilities, (8) sproc_present_query_version, (9) sproc_present_pixmap, (10) sproc_present_notify_msc, (11) sproc_present_select_input, or (12) sproc_present_query_capabilities function in the (a) DRI3 or (b) Present extension. | ||||
| CVE-2017-12187 | 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 RENDER extension allowing malicious X client to cause X server to crash or possibly execute arbitrary code. | ||||
| 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-2022-2319 | 2 Redhat, X.org | 2 Enterprise Linux, X Server | 2025-08-29 | 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-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-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-2015-3418 | 2 Redhat, X.org | 2 Enterprise Linux, X Server | 2025-08-29 | N/A |
| 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-2020-14362 | 3 Canonical, Redhat, X.org | 3 Ubuntu Linux, Enterprise Linux, X Server | 2025-08-29 | 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-2015-3164 | 2 Opensuse, X.org | 3 Opensuse, X Server, Xorg-server | 2025-08-29 | N/A |
| The authentication setup in XWayland 1.16.x and 1.17.x before 1.17.2 starts the server in non-authenticating mode, which allows local users to read from or send information to arbitrary X11 clients via vectors involving a UNIX socket. | ||||
| CVE-2014-8101 | 2 Redhat, X.org | 4 Enterprise Linux, X11, X Server and 1 more | 2025-08-29 | 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-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-2014-8098 | 3 Debian, Redhat, X.org | 5 Debian Linux, Enterprise Linux, X11 and 2 more | 2025-08-29 | N/A |
| 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 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) __glXDisp_Render, (2) __glXDisp_RenderLarge, (3) __glXDispSwap_VendorPrivate, (4) __glXDispSwap_VendorPrivateWithReply, (5) set_client_info, (6) __glXDispSwap_SetClientInfoARB, (7) DoSwapInterval, (8) DoGetProgramString, (9) DoGetString, (10) __glXDispSwap_RenderMode, (11) __glXDisp_GetCompressedTexImage, (12) __glXDispSwap_GetCompressedTexImage, (13) __glXDisp_FeedbackBuffer, (14) __glXDispSwap_FeedbackBuffer, (15) __glXDisp_SelectBuffer, (16) __glXDispSwap_SelectBuffer, (17) __glXDisp_Flush, (18) __glXDispSwap_Flush, (19) __glXDisp_Finish, (20) __glXDispSwap_Finish, (21) __glXDisp_ReadPixels, (22) __glXDispSwap_ReadPixels, (23) __glXDisp_GetTexImage, (24) __glXDispSwap_GetTexImage, (25) __glXDisp_GetPolygonStipple, (26) __glXDispSwap_GetPolygonStipple, (27) __glXDisp_GetSeparableFilter, (28) __glXDisp_GetSeparableFilterEXT, (29) __glXDisp_GetConvolutionFilter, (30) __glXDisp_GetConvolutionFilterEXT, (31) __glXDisp_GetHistogram, (32) __glXDisp_GetHistogramEXT, (33) __glXDisp_GetMinmax, (34) __glXDisp_GetMinmaxEXT, (35) __glXDisp_GetColorTable, (36) __glXDisp_GetColorTableSGI, (37) GetSeparableFilter, (38) GetConvolutionFilter, (39) GetHistogram, (40) GetMinmax, or (41) GetColorTable function. | ||||
| CVE-2023-1393 | 3 Fedoraproject, Redhat, X.org | 7 Fedora, Enterprise Linux, Rhel Aus and 4 more | 2025-08-29 | 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-2014-8097 | 2 Redhat, X.org | 3 Enterprise Linux, X11, X Server | 2025-08-29 | 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. | ||||
