CVSS v3.1 |
| A vulnerability was found in libX11 due to a boundary condition within the _XkbReadKeySyms() function. This flaw allows a local user to trigger an out-of-bounds read error and read the contents of memory on the system. |
| 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. |
| 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. |
| xorg-x11-server before 1.19.5 was missing length validation in X-Resource extension allowing malicious X client to cause X server to crash or possibly execute arbitrary code. |
| 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. |
| 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. |
| xorg-x11-server before 1.19.5 was missing length validation in XFree86 DRI extension allowing malicious X client to cause X server to crash or possibly execute arbitrary code. |
| 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. |
| xorg-x11-server before 1.19.5 was missing extra length validation in ProcEstablishConnection function allowing malicious X client to cause X server to crash or possibly execute arbitrary code. |
| xorg-x11-server before 1.19.5 was missing length validation in XFree86 VidModeExtension allowing malicious X client to cause X server to crash or possibly execute arbitrary code. |
| 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. |
| 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. |
| 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. |
| The SProcXFixesSelectSelectionInput function in the XFixes extension in X.Org X Window System (aka X11 or X) X11R6.8.0 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 value. |
| 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. |
| The Render extension in XFree86 4.0.1, 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) ProcRenderQueryVersion, (2) SProcRenderQueryVersion, (3) SProcRenderQueryPictFormats, (4) SProcRenderQueryPictIndexValues, (5) SProcRenderCreatePicture, (6) SProcRenderChangePicture, (7) SProcRenderSetPictureClipRectangles, (8) SProcRenderFreePicture, (9) SProcRenderComposite, (10) SProcRenderScale, (11) SProcRenderCreateGlyphSet, (12) SProcRenderReferenceGlyphSet, (13) SProcRenderFreeGlyphSet, (14) SProcRenderFreeGlyphs, or (15) SProcRenderCompositeGlyphs function. |

| The XVideo extension in XFree86 4.0.0, 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) SProcXvQueryExtension, (2) SProcXvQueryAdaptors, (3) SProcXvQueryEncodings, (4) SProcXvGrabPort, (5) SProcXvUngrabPort, (6) SProcXvPutVideo, (7) SProcXvPutStill, (8) SProcXvGetVideo, (9) SProcXvGetStill, (10) SProcXvPutImage, (11) SProcXvShmPutImage, (12) SProcXvSelectVideoNotify, (13) SProcXvSelectPortNotify, (14) SProcXvStopVideo, (15) SProcXvSetPortAttribute, (16) SProcXvGetPortAttribute, (17) SProcXvQueryBestSize, (18) SProcXvQueryPortAttributes, (19) SProcXvQueryImageAttributes, or (20) SProcXvListImageFormats function. |

| 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. |
