CVE-2014-8101 – xorg-x11-server: out of bounds access due to not validating length or offset values in RandR extension
https://notcve.org/view.php?id=CVE-2014-8101
The RandR extension in XFree86 4.2.0, X.Org X Window System (aka X11 or X) X11R6.7, and X.Org Server (aka xserver and xorg-server) before 1.16.3 allows remote authenticated users to cause a denial of service (out-of-bounds read or write) or possibly execute arbitrary code via a crafted length or index value to the (1) SProcRRQueryVersion, (2) SProcRRGetScreenInfo, (3) SProcRRSelectInput, or (4) SProcRRConfigureOutputProperty function. La extensión RandR en XFree86 4.2.0, X.Org X Window System (también conocido como X11 o X) X11R6.7, y X.Org Server (también conocido como xserver y xorg-server) anterior a 1.16.3 permite a usuarios remotos autenticados causar una denegación de servicio (lectura o escritura fuera de rango) o posiblemente ejecutar código arbitrario a través de una longitud manipulada o un valor de indice manipulado en la función (1) SProcRRQueryVersion, (2) SProcRRGetScreenInfo, (3) SProcRRSelectInput, o (4) SProcRRConfigureOutputProperty. Multiple out-of-bounds access flaws were found in the way the X.Org server calculated memory requirements for certain requests. A malicious, authenticated client could use either of these flaws to crash the X.Org server. • 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/cpujul2015-2367936.html http://www.securityfocus.com/bid/71605 http://www.x.org/wiki/Development/Security/Advisory-2014-12-09 https • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-125: Out-of-bounds Read •
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 •
