CVSS v3.1 |
| A single byte overflow in catalogue.c in X.Org libXfont 1.3.1 allows remote attackers to have unspecified impact. |
| libXcursor before 1.1.15 has various integer overflows that could lead to heap buffer overflows when processing malicious cursors, e.g., with programs like GIMP. It is also possible that an attack vector exists against the related code in cursor/xcursor.c in Wayland through 1.14.0. |
| In libXfont before 1.5.4 and libXfont2 before 2.0.3, a local attacker can open (but not read) files on the system as root, triggering tape rewinds, watchdogs, or similar mechanisms that can be triggered by opening files. |
| Directory traversal vulnerability in tools/backlight_helper.c in X.Org xf86-video-intel 2.99.911 allows remote attackers to create or overwrite arbitrary files via a .. (dot dot) in the interface name. |
| The bdfReadProperties function in bitmap/bdfread.c in X.Org libXfont before 1.4.9 and 1.5.x before 1.5.1 allows remote authenticated users to cause a denial of service (out-of-bounds write and crash) or possibly execute arbitrary code via a (1) negative or (2) large property count in a BDF font file. |
| The bdfReadCharacters function in bitmap/bdfread.c in X.Org libXfont before 1.4.9 and 1.5.x before 1.5.1 does not properly handle character bitmaps it cannot read, which allows remote authenticated users to cause a denial of service (NULL pointer dereference and crash) and possibly execute arbitrary code via a crafted BDF font file. |
| The bdfReadCharacters function in bitmap/bdfread.c in X.Org libXfont before 1.4.9 and 1.5.x before 1.5.1 does not properly perform type conversion for metrics values, which allows remote authenticated users to cause a denial of service (out-of-bounds memory access) and possibly execute arbitrary code via a crafted BDF font file. |
| Multiple integer overflows in the (1) FontFileAddEntry and (2) lexAlias functions in X.Org libXfont before 1.4.8 and 1.4.9x before 1.4.99.901 might allow local users to gain privileges by adding a directory with a large fonts.dir or fonts.alias file to the font path, which triggers a heap-based buffer overflow, related to metadata. |
| Multiple buffer overflows in X.Org libXfont before 1.4.8 and 1.4.9x before 1.4.99.901 allow remote font servers to execute arbitrary code via a crafted xfs protocol reply to the (1) _fs_recv_conn_setup, (2) fs_read_open_font, (3) fs_read_query_info, (4) fs_read_extent_info, (5) fs_read_glyphs, (6) fs_read_list, or (7) fs_read_list_info function. |
| Multiple integer overflows in the (1) fs_get_reply, (2) fs_alloc_glyphs, and (3) fs_read_extent_info functions in X.Org libXfont before 1.4.8 and 1.4.9x before 1.4.99.901 allow remote font servers to execute arbitrary code via a crafted xfs reply, which triggers a buffer overflow. |
| Multiple integer overflows in X.org libXtst before 1.2.3 allow remote X servers to trigger out-of-bounds memory access operations by leveraging the lack of range checks. |
| Multiple integer overflows in X.org libXxf86dga 1.1.3 and earlier allow X servers to trigger allocation of insufficient memory and a buffer overflow via vectors related to the (1) XDGAQueryModes and (2) XDGASetMode functions. |
| X.Org X server before 1.13.4 and 1.4.x before 1.14.1 does not properly restrict access to input events when adding a new hot-plug device, which might allow physically proximate attackers to obtain sensitive information, as demonstrated by reading passwords from a tty. |
| Multiple integer overflows in X.org libdmx 1.1.2 and earlier allow X servers to trigger allocation of insufficient memory and a buffer overflow via vectors related to the (1) DMXGetScreenAttributes, (2) DMXGetWindowAttributes, and (3) DMXGetInputAttributes functions. |
| Multiple integer overflows in X.org libXvMC 1.0.7 and earlier allow X servers to trigger allocation of insufficient memory and a buffer overflow via vectors related to the (1) XvMCListSurfaceTypes and (2) XvMCListSubpictureTypes functions. |
| Multiple integer overflows in X.org libXRes 1.0.6 and earlier allow X servers to trigger allocation of insufficient memory and a buffer overflow via vectors related to the (1) XResQueryClients and (2) XResQueryClientResources functions. |
| The ProcSetEventMask function in difs/events.c in the xfs font server for X.Org X11R6 through X11R6.6 and XFree86 before 3.3.3 calls the SendErrToClient function with a mask value instead of a pointer, which allows local users to cause a denial of service (memory corruption and crash) or obtain potentially sensitive information from memory via a SetEventMask request that triggers an invalid pointer dereference. |
| X.org libXt 1.1.3 and earlier does not check the return value of the XGetWindowProperty function, which allows X servers to trigger use of an uninitialized pointer and memory corruption via vectors related to the (1) ReqCleanup, (2) HandleSelectionEvents, (3) ReqTimedOut, (4) HandleNormal, and (5) HandleSelectionReplies functions. |
| Multiple integer overflows in X.org libXrender 0.9.7 and earlier allow X servers to trigger allocation of insufficient memory and a buffer overflow via vectors related to the (1) XRenderQueryFilters, (2) XRenderQueryFormats, and (3) XRenderQueryPictIndexValues functions. |
| Integer overflow in X.org libXcursor 1.1.13 and earlier allows X servers to trigger allocation of insufficient memory and a buffer overflow via vectors related to the _XcursorFileHeaderCreate function. |
