CVE-2013-1982 – libXext: Multiple integer overflows leading to heap-based buffer-overflows

https://notcve.org/view.php?id=CVE-2013-1982

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. Múltiples desbordamientos de enteros en X.org libXext v1.3.1 y anteriores permiten a los servidores X para activar la asignación de memoria insuficiente y un desbordamiento de búfer a través de vectores relacionados con las funciones (1) XcupGetReservedColormapEntries, (2) XcupStoreColors, (3) XdbeGetVisualInfo, (4) XeviGetVisualInfo , (5) XShapeGetRectangles, y (6) XSyncListSystemCounters. • http://lists.opensuse.org/opensuse-updates/2013-06/msg00139.html http://www.debian.org/security/2013/dsa-2682 http://www.openwall.com/lists/oss-security/2013/05/23/3 http://www.ubuntu.com/usn/USN-1857-1 http://www.x.org/wiki/Development/Security/Advisory-2013-05-23 https://access.redhat.com/security/cve/CVE-2013-1982 https://bugzilla.redhat.com/show_bug.cgi?id=959046 • CWE-122: Heap-based Buffer Overflow CWE-189: Numeric Errors •
