The Elf parser (libelf) in Xen 4.2.x and earlier allow local guest administrators with certain permissions to have an unspecified impact via a crafted kernel, related to "pointer dereferences" involving unexpected calculations. El analizador ELF (libelf) in Xen v4.2.x y anteriores permite a los administradores invitados locales con ciertos permisos, tener un impacto no especificado a través de un kernel hecho manipulado, en relación con "desreferencia de puntero" que involucran cálculos inesperados. • http://lists.opensuse.org/opensuse-security-announce/2014-03/msg00015.html http://lists.opensuse.org/opensuse-security-announce/2014-03/msg00021.html http://lists.opensuse.org/opensuse-security-announce/2014-04/msg00000.html http://secunia.com/advisories/55082 http://security.gentoo.org/glsa/glsa-201309-24.xml http://support.citrix.com/article/CTX138058 http://www.debian.org/security/2014/dsa-3006 http://www.openwall.com/lists/oss-security/2013/06/20/2 http://www.openwall.com/ • CWE-189: Numeric Errors •

CVE-2013-1917
https://notcve.org/view.php?id=CVE-2013-1917
Xen 3.1 through 4.x, when running 64-bit hosts on Intel CPUs, does not clear the NT flag when using an IRET after a SYSENTER instruction, which allows PV guest users to cause a denial of service (hypervisor crash) by triggering a #GP fault, which is not properly handled by another IRET instruction. Xen 3.1 a la 4.x, cuando ejecuta hosts con arquitectura de 64 bits en CPUs Intel, no limpia la bandera NT cuan emplea una IRET después de una instrucción SYSENTER, lo que permite a usuarios PV provocar una denegación de servicio (caída del hypervisor) provocando un fallo #GP que no está manejado adecuadamente por otra instrucción IRET. • http://lists.fedoraproject.org/pipermail/package-announce/2013-May/104537.html http://lists.opensuse.org/opensuse-security-announce/2014-03/msg00015.html http://lists.opensuse.org/opensuse-security-announce/2014-03/msg00021.html http://lists.opensuse.org/opensuse-security-announce/2014-04/msg00000.html http://lists.opensuse.org/opensuse-updates/2013-06/msg00049.html http://secunia.com/advisories/55082 http://security.gentoo.org/glsa/glsa-201309-24.xml http://www.debian.org/security/2012/dsa-2 • CWE-20: Improper Input Validation •
CVE-2013-1920
https://notcve.org/view.php?id=CVE-2013-1920
Xen 4.2.x, 4.1.x, and earlier, when the hypervisor is running "under memory pressure" and the Xen Security Module (XSM) is enabled, uses the wrong ordering of operations when extending the per-domain event channel tracking table, which causes a use-after-free and allows local guest kernels to inject arbitrary events and gain privileges via unspecified vectors. Xen v4.2.x, v4.1.x, y anteriores, cuando el hypervisor se está ejecutando "bajo presión de memoria" y el Módulo de Seguridad Xen (XSM) está activado, usa un orden de operaciones incorrecto cuando se extiende la tabla de seguimiento del canal de eventos por dominio, lo que ocasiona una vulnerabilidad de uso después de liberación y permite inyectar eventos de su elección a los núcleos locales de clientes y obtener privilegios a través de vectores no especificados. • http://lists.opensuse.org/opensuse-security-announce/2014-03/msg00015.html http://lists.opensuse.org/opensuse-security-announce/2014-03/msg00021.html http://lists.opensuse.org/opensuse-security-announce/2014-04/msg00000.html http://lists.opensuse.org/opensuse-updates/2013-06/msg00049.html http://lists.xen.org/archives/html/xen-announce/2013-04/msg00000.html http://osvdb.org/92050 http://secunia.com/advisories/52857 http://secunia.com/advisories/55082 http://security.gentoo.org/glsa/gls • CWE-264: Permissions, Privileges, and Access Controls •
