CVE-2011-2895 6 Freebsd, Freetype, Netbsd and 3 more 7 Freebsd, Freetype, Netbsd and 4 more 2025-04-11 N/A
The LZW decompressor in (1) the BufCompressedFill function in fontfile/decompress.c in X.Org libXfont before 1.4.4 and (2) compress/compress.c in 4.3BSD, as used in zopen.c in OpenBSD before 3.8, FreeBSD, NetBSD 4.0.x and 5.0.x before 5.0.3 and 5.1.x before 5.1.1, FreeType 2.1.9, and other products, does not properly handle code words that are absent from the decompression table when encountered, which allows context-dependent attackers to trigger an infinite loop or a heap-based buffer overflow, and possibly execute arbitrary code, via a crafted compressed stream, a related issue to CVE-2006-1168 and CVE-2011-2896.
CVE-2012-0064 2 X, Xkeyboard Config Project 2 X.org X11, Xkeyboard-config 2025-04-11 N/A
xkeyboard-config before 2.5 in X.Org before 7.6 enables certain XKB debugging functions by default, which allows physically proximate attackers to bypass an X screen lock via keyboard combinations that break the input grab.
CVE-2012-1699 2 X, Xfree86 2 X.org X11, Xfree86 2025-04-11 N/A
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.
CVE-2013-1940 3 Canonical, Redhat, X 3 Ubuntu Linux, Enterprise Linux, X.org-xserver 2025-04-11 N/A
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.
CVE-2013-1981 3 Canonical, Redhat, X 3 Ubuntu Linux, Enterprise Linux, Libx11 2025-04-11 N/A
Multiple integer overflows in X.org libX11 1.5.99.901 (1.6 RC1) and earlier allow X servers to trigger allocation of insufficient memory and a buffer overflow via vectors related to the (1) XQueryFont, (2) _XF86BigfontQueryFont, (3) XListFontsWithInfo, (4) XGetMotionEvents, (5) XListHosts, (6) XGetModifierMapping, (7) XGetPointerMapping, (8) XGetKeyboardMapping, (9) XGetWindowProperty, (10) XGetImage, (11) LoadColornameDB, (12) XrmGetFileDatabase, (13) _XimParseStringFile, or (14) TransFileName functions.
CVE-2013-1982 2 Redhat, X 2 Enterprise Linux, Libxext 2025-04-11 N/A
Multiple integer overflows in X.org libXext 1.3.1 and earlier allow X servers to trigger allocation of insufficient memory and a buffer overflow via vectors related to the (1) XcupGetReservedColormapEntries, (2) XcupStoreColors, (3) XdbeGetVisualInfo, (4) XeviGetVisualInfo, (5) XShapeGetRectangles, and (6) XSyncListSystemCounters functions.
CVE-2013-1983 2 Redhat, X 2 Enterprise Linux, Libxfixes 2025-04-11 N/A
Integer overflow in X.org libXfixes 5.0 and earlier allows X servers to trigger allocation of insufficient memory and a buffer overflow via vectors related to the XFixesGetCursorImage function.
CVE-2008-2362 2 Redhat, X 2 Enterprise Linux, X11 2025-04-09 N/A
Multiple integer overflows in the Render extension in the X server 1.4 in X.Org X11R7.3 allow context-dependent attackers to execute arbitrary code via a (1) SProcRenderCreateLinearGradient, (2) SProcRenderCreateRadialGradient, or (3) SProcRenderCreateConicalGradient request with an invalid field specifying the number of bytes to swap in the request data, which triggers heap memory corruption.
CVE-2008-2360 2 Redhat, X 2 Enterprise Linux, X11 2025-04-09 N/A
Integer overflow in the AllocateGlyph function in the Render extension in the X server 1.4 in X.Org X11R7.3 allows context-dependent attackers to execute arbitrary code via unspecified request fields that are used to calculate a heap buffer size, which triggers a heap-based buffer overflow.
CVE-2008-1379 2 Redhat, X 2 Enterprise Linux, X11 2025-04-09 N/A
Integer overflow in the fbShmPutImage function in the MIT-SHM extension in the X server 1.4 in X.Org X11R7.3 allows context-dependent attackers to read arbitrary process memory via crafted values for a Pixmap width and height.
CVE-2008-1377 2 Redhat, X 2 Enterprise Linux, X11 2025-04-09 N/A
The (1) SProcRecordCreateContext and (2) SProcRecordRegisterClients functions in the Record extension and the (3) SProcSecurityGenerateAuthorization function in the Security extension in the X server 1.4 in X.Org X11R7.3 allow context-dependent attackers to execute arbitrary code via requests with crafted length values that specify an arbitrary number of bytes to be swapped on the heap, which triggers heap corruption.
CVE-2015-9262 4 Canonical, Debian, Redhat and 1 more 8 Ubuntu Linux, Debian Linux, Ansible Tower and 5 more 2024-11-21 N/A
_XcursorThemeInherits in library.c in libXcursor before 1.1.15 allows remote attackers to cause denial of service or potentially code execution via a one-byte heap overflow.
