The emulation routines for unspecified X86 devices in Xen 3.2.x through 4.5.x does not properly initialize data, which allow local HVM guest users to obtain sensitive information via vectors involving an unsupported access size. Las rutinas de emulación para dispositivos X86 no especificados en Xen 3.2.x hasta 4.5.x no inicializa correctamente los datos, lo que permite a usuarios locales invitados HVM obtener información sensible a través de vectores que involucran un tamaño de acceso no soportado. • http://lists.fedoraproject.org/pipermail/package-announce/2015-March/152483.html http://lists.fedoraproject.org/pipermail/package-announce/2015-March/152588.html http://lists.fedoraproject.org/pipermail/package-announce/2015-March/152776.html http://lists.opensuse.org/opensuse-security-announce/2015-04/msg00014.html http://support.citrix.com/article/CTX200484 http://www.debian.org/security/2015/dsa-3181 http://www.securityfocus.com/bid/72954 http://www.securitytracker.com/id/1031806 http://www. • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

CVSS: 7.2EPSS: 0%CPEs: 38EXPL: 0CVE-2015-2151 – xen: hypervisor memory corruption due to x86 emulator flaw (xsa123)
https://notcve.org/view.php?id=CVE-2015-2151
The x86 emulator in Xen 3.2.x through 4.5.x does not properly ignore segment overrides for instructions with register operands, which allows local guest users to obtain sensitive information, cause a denial of service (memory corruption), or possibly execute arbitrary code via unspecified vectors. El emulador x86 en Xen 3.2.x hasta 4.5.x no ignora correctamente las anulaciones de segmentos para instrucciones con operandos del registro, lo que permite a usuarios locales invitados obtener información sensible, causar una denegación de servicio (corrupción de memoria), o posiblemente ejecutar código arbitrario a través de vectores no especificados. It was found that the Xen hypervisor x86 CPU emulator implementation did not correctly handle certain instructions with segment overrides, potentially resulting in a memory corruption. A malicious guest user could use this flaw to read arbitrary data relating to other guests, cause a denial of service on the host, or potentially escalate their privileges on the host. • http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10761 http://lists.fedoraproject.org/pipermail/package-announce/2015-March/152483.html http://lists.fedoraproject.org/pipermail/package-announce/2015-March/152588.html http://lists.fedoraproject.org/pipermail/package-announce/2015-March/152776.html http://lists.opensuse.org/opensuse-security-announce/2015-04/msg00014.html http://support.citrix.com/article/CTX200484 http://www.debian.org/security/2015/dsa-3181 http://www.oracle.com/technetwork/ • CWE-264: Permissions, Privileges, and Access Controls •
