The xlu_vif_parse_rate function in the libxlu library in Xen 4.2.x and 4.3.x allows local users to cause a denial of service (NULL pointer dereference) by using the "@" character as the VIF rate configuration. La función xlu_vif_parse_rate en la librería libxlu de Xen 4.2.x y 4.3.x permite a usuarios locales causar una denegación de servicio (referencia puntero nulo) utilizando el caracter '@' como configuración de velocidad VIF. • http://security.gentoo.org/glsa/glsa-201407-03.xml http://www.openwall.com/lists/oss-security/2013/10/10/11 https://exchange.xforce.ibmcloud.com/vulnerabilities/87798 •
CVSS: 2.3EPSS: 0%CPEs: 34EXPL: 0CVE-2013-4368 – xen: information leak through outs instruction emulation (XSA-67)
https://notcve.org/view.php?id=CVE-2013-4368
The outs instruction emulation in Xen 3.1.x, 4.2.x, 4.3.x, and earlier, when using FS: or GS: segment override, uses an uninitialized variable as a segment base, which allows local 64-bit PV guests to obtain sensitive information (hypervisor stack content) via unspecified vectors related to stale data in a segment register. La instrucción de emulación outs en Xen 3.1.x, 4.2.x, 4.3.x, y anteriores versiones, cuando se usa la anulación del segmento FS: o GS:, utiliza una variable sin inicializar como segmento base, lo que permite a usuarios locales de 64-bit PV obtener información sensible (contenido de la pila de hipervisor) a través de vectores relacionados de datos obsoletos en un registro del segmento. • 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/2013-11/msg00009.html http://rhn.redhat.com/errata/RHSA-2013-1449.html http://security.gentoo.org/glsa/glsa-201407-03.xml http://www.debian.org/security/2014/dsa-3006 http://www.openwall.com/lists/oss-security/2013/10 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

Xen 4.3.x writes hypervisor mappings to certain shadow pagetables when live migration is performed on hosts with more than 5TB of RAM, which allows local 64-bit PV guests to read or write to invalid memory and cause a denial of service (crash). Xen 4.3.x escribe asignaciones de hypervisor a ciertas "shadow pagetables" cuando la migración en vivo se realiza en máquinas con más de 5 TB de RAM, lo que permite a usuarios locales de 64-bit PV leer o escribir en memoria no válida y provocar una denegación de servicio (caída). • http://secunia.com/advisories/54962 http://security.gentoo.org/glsa/glsa-201407-03.xml http://www.openwall.com/lists/oss-security/2013/09/30/2 http://www.securityfocus.com/bid/62709 • CWE-264: Permissions, Privileges, and Access Controls •

The fbld instruction emulation in Xen 3.3.x through 4.3.x does not use the correct variable for the source effective address, which allows local HVM guests to obtain hypervisor stack information by reading the values used by the instruction. La emulación de la instrucción fbld en Xen 3.3.x a 4.3.x no usa la variable correcta para la dirección de origen efectiva, lo cual permite a invitados HVM locales obtener información de la pila del hypervisor mediante la lectura de valores usados por la instrucción. • http://lists.opensuse.org/opensuse-security-announce/2014-03/msg00021.html http://lists.opensuse.org/opensuse-updates/2013-11/msg00009.html http://security.gentoo.org/glsa/glsa-201407-03.xml http://www.debian.org/security/2014/dsa-3006 http://www.openwall.com/lists/oss-security/2013/09/30/3 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

Xen 4.3.x and earlier does not properly handle certain errors, which allows local HVM guests to obtain hypervisor stack memory via a (1) port or (2) memory mapped I/O write or (3) other unspecified operations related to addresses without associated memory. Xen v4.3.x y anterior no maneja correctamente ciertos errores, lo que permite a invitados locales HVM conseguir la memoria de la pila del hypervisor a través de un puerto o escritura de memoria mapeada de I/O u otra operación no especificada relacionada con direcciones sin memoria asociada. • 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/2013-11/msg00009.html http://rhn.redhat.com/errata/RHSA-2013-1790.html http://security.gentoo.org/glsa/glsa-201407-03.xml http://www.debian.org/security/2014/dsa-3006 http://www.openwall.com/lists/oss-security/2013/09 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
