https://notcve.org/view.php?id=CVE-2013-1997
Multiple buffer overflows in X.org libX11 1.5.99.901 (1.6 RC1) and earlier allow X servers to cause a denial of service (crash) and possibly execute arbitrary code via crafted length or index values to the (1) XAllocColorCells, (2) _XkbReadGetDeviceInfoReply, (3) _XkbReadGeomShapes, (4) _XkbReadGetGeometryReply, (5) _XkbReadKeySyms, (6) _XkbReadKeyActions, (7) _XkbReadKeyBehaviors, (8) _XkbReadModifierMap, (9) _XkbReadExplicitComponents, (10) _XkbReadVirtualModMap, (11) _XkbReadGetNamesReply, (12) _XkbReadGetMapReply, (13) _XimXGetReadData, (14) XListFonts, (15) XListExtensions, and (16) XGetFontPath functions. Multiples desbordamientos de búfer en X.org libX11 v1.5.99.901 (1.6 RC1) y anteriores permite a los servidores X causar una denegación de servicio (por caída del servidor) y posiblemente ejecutar código de su elección a través de valores de índice o de longitud debidamente modificados en las funciones (1) XAllocColorCells, (2) _XkbReadGetDeviceInfoReply, (3) _XkbReadGeomShapes, (4) _XkbReadGetGeometryReply, (5) _XkbReadKeySyms, (6) _XkbReadKeyActions, (7) _XkbReadKeyBehaviors, (8) _XkbReadModifierMap, (9) _XkbReadExplicitComponents, (10) _XkbReadVirtualModMap, (11) _XkbReadGetNamesReply, (12) _XkbReadGetMapReply, (13) _XimXGetReadData, (14) XListFonts, (15) XListExtensions, y (16) XGetFontPath. • http://lists.fedoraproject.org/pipermail/package-announce/2013-May/106781.html http://www.debian.org/security/2013/dsa-2693 http://www.openwall.com/lists/oss-security/2013/05/23/3 http://www.ubuntu.com/usn/USN-1854-1 http://www.x.org/wiki/Development/Security/Advisory-2013-05-23 https://access.redhat.com/security/cve/CVE-2013-1997 https://bugzilla.redhat.com/show_bug.cgi?id=960345 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-122: Heap-based Buffer Overflow •
CVE-2007-1667 – XGetPixel() integer overflow
https://notcve.org/view.php?id=CVE-2007-1667
Multiple integer overflows in (1) the XGetPixel function in ImUtil.c in X.Org libx11 before 1.0.3, and (2) XInitImage function in xwd.c for ImageMagick, allow user-assisted remote attackers to cause a denial of service (crash) or obtain sensitive information via crafted images with large or negative values that trigger a buffer overflow. Múltiples desbordamientos de enteros en (1) la función XGetPixel en el archivo ImUtil.c en X.Org libx11 anterior a la versión 1.0.3 y (2) la función XInitImage en el archivo xwd.c para ImageMagick, permiten a los atacantes remotos asistidos por el usuario causar una denegación de servicio (bloqueo) o obtener información confidencial por medio de imágenes elaboradas con valores grandes o negativos que desencadenan un desbordamiento de búfer. • http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=414045 http://issues.foresightlinux.org/browse/FL-223 http://lists.apple.com/archives/security-announce/2009/Feb/msg00000.html http://lists.freedesktop.org/archives/xorg-announce/2007-April/000286.html http://rhn.redhat.com/errata/RHSA-2007-0125.html http://secunia.com/advisories/24739 http://secunia.com/advisories/24741 http://secunia.com/advisories/24745 http://secunia.com/advisories/24756 http://secunia.com/advisories/24758 htt • CWE-189: Numeric Errors •
