Xen 4.4.x and earlier, when using a large number of VCPUs, does not properly handle read and write locks, which allows local x86 guest users to cause a denial of service (write denial or NMI watchdog timeout and host crash) via a large number of read requests, a different vulnerability than CVE-2014-9065. Xen 4.4.x y versiones anteriores, cuando utiliza un gran número de VCPUs, no maneja adecuadamente los bloqueos de lectura y escritura, lo que permite a usuarios invitados x86 locales causar una denegación de servicio (denegación de escritura o tiempo de espera agotado del watchdog NMI y caida de host) a través de un gran número de peticiones de lectura, una vulnerabilidad diferente a CVE-2014-9065. • http://lists.opensuse.org/opensuse-security-announce/2015-02/msg00005.html http://lists.opensuse.org/opensuse-security-announce/2015-02/msg00010.html http://www.openwall.com/lists/oss-security/2014/12/08/4 http://www.securityfocus.com/bid/71546 http://xenbits.xen.org/xsa/advisory-114.html https://security.gentoo.org/glsa/201504-04 • CWE-17: DEPRECATED: Code •

CVSS: 4.6EPSS: 0%CPEs: 10EXPL: 2CVE-2014-9273 – hivex: missing checks for small-sized files
https://notcve.org/view.php?id=CVE-2014-9273
lib/handle.c in Hivex before 1.3.11 allows local users to execute arbitrary code and gain privileges via a small hive files, which triggers an out-of-bounds read or write. lib/handle.c en Hivex anterior a 1.3.11 permite a usuarios locales ejecutar código arbitrario y ganar privilegios a través de un fichero de hive pequeño, lo que provoca una lectura o escritura fuera de rango. It was found that hivex attempted to read, and possibly write, beyond its allocated buffer when reading a hive file with a very small size or with a truncated or improperly formatted content. An attacker able to supply a specially crafted hive file to an application using the hivex library could possibly use this flaw to execute arbitrary code with the privileges of the user running that application. • http://lists.opensuse.org/opensuse-updates/2015-02/msg00005.html http://rhn.redhat.com/errata/RHSA-2015-0301.html http://rhn.redhat.com/errata/RHSA-2015-1378.html http://secunia.com/advisories/62792 http://www.openwall.com/lists/oss-security/2014/11/25/6 http://www.openwall.com/lists/oss-security/2014/12/04/14 http://www.securityfocus.com/bid/71279 https://bugzilla.redhat.com/show_bug.cgi?id=1167756 https://github.com/libguestfs/hivex/commit/357f26fa64fd1d9ccac2331fe174a8ee • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •
