CVE-2014-8091 – xorg-x11-server: denial of service due to unchecked malloc in client authentication
https://notcve.org/view.php?id=CVE-2014-8091
X.Org X Window System (aka X11 and X) X11R5 and X.Org Server (aka xserver and xorg-server) before 1.16.3, when using SUN-DES-1 (Secure RPC) authentication credentials, does not check the return value of a malloc call, which allows remote attackers to cause a denial of service (NULL pointer dereference and server crash) via a crafted connection request. X.Org X Window System (también conocido como X11 and X) X11R5 y X.Org Server (también conocido como xserver y xorg-server) anterior a 1.16.3, cuando utiliza las credenciales de autenticación SUN-DES-1 (Secure RPC), no compreuba el valor de retorno de una llamada malloc, lo que permite a atacantes remotos causar una denegación de servicio (referencia a puntero nulo y caída de servidor) a través de una solicitud de conexión manipulada. It was found that the X.Org server did not properly handle SUN-DES-1 (Secure RPC) authentication credentials. A malicious, unauthenticated client could use this flaw to crash the X.Org server by submitting a specially crafted authentication request. • http://advisories.mageia.org/MGASA-2014-0532.html http://secunia.com/advisories/61947 http://secunia.com/advisories/62292 http://www.debian.org/security/2014/dsa-3095 http://www.mandriva.com/security/advisories?name=MDVSA-2015:119 http://www.oracle.com/technetwork/topics/security/bulletinjan2015-2370101.html http://www.oracle.com/technetwork/topics/security/bulletinoct2015-2511968.html http://www.oracle.com/technetwork/topics/security/cpujul2015-2367936.html http://www.securityfocus.com/bid/71597& • CWE-252: Unchecked Return Value •
CVE-2011-0465 – xorg: xrdb code execution via crafted X client hostname
https://notcve.org/view.php?id=CVE-2011-0465
xrdb.c in xrdb before 1.0.9 in X.Org X11R7.6 and earlier allows remote attackers to execute arbitrary commands via shell metacharacters in a hostname obtained from a (1) DHCP or (2) XDMCP message. xrdb.c en xrdb anterior a v1.0.9 en X.Org X11R7.6 y anteriores permite a atacantes remotos ejecutar comandos arbitrarios mediante metacaracteres en un hostname obtenido de un mensaje (1) DHCP o (2) XDMCP. • http://cgit.freedesktop.org/xorg/app/xrdb/commit/?id=1027d5df07398c1507fb1fe3a9981aa6b4bc3a56 http://lists.fedoraproject.org/pipermail/package-announce/2011-April/057928.html http://lists.freedesktop.org/archives/xorg-announce/2011-April/001635.html http://lists.freedesktop.org/archives/xorg-announce/2011-April/001636.html http://lists.opensuse.org/opensuse-security-announce/2011-04/msg00002.html http://secunia.com/advisories/44010 http://secunia.com/advisories/44012 http://secunia.com/advisories/44040 http • CWE-20: Improper Input Validation •
