https://notcve.org/view.php?id=CVE-2013-1992

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. Múltiples desbordamientos de enteros en X.org libdmx v1.1.2 y anteriores permiten que los servidores X provoquen una asignación de memoria insuficiente y un desbordamiento de búfer a través de vectores relacionados con las funciones (1) DMXGetScreenAttributes, (2) DMXGetWindowAttributes y (3) DMXGetInputAttributes. • http://lists.fedoraproject.org/pipermail/package-announce/2013-May/107024.html http://lists.opensuse.org/opensuse-updates/2013-06/msg00157.html http://www.debian.org/security/2013/dsa-2673 http://www.openwall.com/lists/oss-security/2013/05/23/3 http://www.ubuntu.com/usn/USN-1852-1 http://www.x.org/wiki/Development/Security/Advisory-2013-05-23 https://access.redhat.com/security/cve/CVE-2013-1992 https://bugzilla.redhat.com/show_bug.cgi?id=959074 • CWE-122: Heap-based Buffer Overflow CWE-189: Numeric Errors •
