CVSS: 6.5EPSS: 1%CPEs: 3EXPL: 0CVE-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 •
CVSS: 4.3EPSS: 6%CPEs: 2EXPL: 0CVE-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 •

Buffer overflow in the compNewPixmap function in compalloc.c in the Composite extension for the X.org X11 server before 1.4 allows local users to execute arbitrary code by copying data from a large pixel depth pixmap into a smaller pixel depth pixmap. Desbordamiento de búfer en la función compNewPixmap de compalloc.c en la extensión Composite para el servidor X11 X.org anterior a 1.4 permite a usuarios locales ejecutar código de su elección copiando datos de un mapa de píxeles con gran profundidad de píxel (pixel depth) a un mapa con profundidad menor. • http://bugs.freedesktop.org/show_bug.cgi?id=7447 http://bugs.gentoo.org/show_bug.cgi?id=191964 http://lists.freedesktop.org/archives/xorg-announce/2007-September/000378.html http://osvdb.org/37726 http://secunia.com/advisories/26743 http://secunia.com/advisories/26755 http://secunia.com/advisories/26763 http://secunia.com/advisories/26823 http://secunia.com/advisories/26859 http://secunia.com/advisories/26897 http://secunia.com/advisories/27147 http://secunia.com/adviso • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

X.Org and XFree86, including libX11, xdm, xf86dga, xinit, xload, xtrans, and xterm, does not check the return values for setuid and seteuid calls when attempting to drop privileges, which might allow local users to gain privileges by causing those calls to fail, such as by exceeding a ulimit.
