The compat_iret function in Xen 3.1 through 4.5 iterates the wrong way through a loop, which allows local 32-bit PV guest administrators to cause a denial of service (large loop and system hang) via a hypercall_iret call with EFLAGS.VM set. La función compat_iret en Xen 3.1 hasta 4.5 itera en la dirección errónea a través de un bucle, lo que permite a administradores locales invitados de PV de 32 dits causar una denegación de servicio (bucle grande y cuelgue del sistema) a través de una llamada hypercall_iret con el juego EFLAGS.VM. • http://lists.opensuse.org/opensuse-security-announce/2015-06/msg00004.html http://lists.opensuse.org/opensuse-security-announce/2015-06/msg00007.html http://lists.opensuse.org/opensuse-security-announce/2015-06/msg00029.html http://lists.opensuse.org/opensuse-security-announce/2015-06/msg00030.html http://lists.opensuse.org/opensuse-security-announce/2015-07/msg00014.html http://lists.opensuse.org/opensuse-security-announce/2015-09/msg00027.html http://support.citrix.com/article/CTX201145 http://www. • CWE-399: Resource Management Errors •

Xen 3.3.x through 4.5.x does not properly restrict write access to the host MSI message data field, which allows local x86 HVM guest administrators to cause a denial of service (host interrupt handling confusion) via vectors related to qemu and accessing spanning multiple fields. Xen 3.3.x hasta la versión 4.5.x no restringe correctamente el acceso a escritura al campo de datos del mensaje MSI del host, lo que permite a administradores invitados x86 HVM locales causar una denegación de servicio (confusión en el manejo de interrupción de host) a través de vectores relacionados con qemu y accediendo a múltiples campos de expansión. • http://lists.fedoraproject.org/pipermail/package-announce/2015-June/160154.html http://lists.fedoraproject.org/pipermail/package-announce/2015-June/160171.html http://lists.fedoraproject.org/pipermail/package-announce/2015-June/160685.html http://lists.opensuse.org/opensuse-security-announce/2015-06/msg00004.html http://lists.opensuse.org/opensuse-security-announce/2015-06/msg00007.html http://lists.opensuse.org/opensuse-security-announce/2015-06/msg00029.html http://lists.opensuse.org/opensuse-security-announce&#x • CWE-264: Permissions, Privileges, and Access Controls •

Xen 3.3.x through 4.5.x does not properly restrict access to PCI MSI mask bits, which allows local x86 HVM guest users to cause a denial of service (unexpected interrupt and host crash) via unspecified vectors. Xen 3.3.x hasta 4.5.x no restringe correctamente el acceso a los bits de máscara PCI MSI, lo que permite a usuarios locales invitados de x86 HVM causar una denegación de servicio (interrupción no esperado y caída de anfitrión) a través de vectores no especificados. • http://lists.fedoraproject.org/pipermail/package-announce/2015-June/160154.html http://lists.fedoraproject.org/pipermail/package-announce/2015-June/160171.html http://lists.fedoraproject.org/pipermail/package-announce/2015-June/160685.html http://lists.opensuse.org/opensuse-security-announce/2015-06/msg00004.html http://lists.opensuse.org/opensuse-security-announce/2015-06/msg00007.html http://lists.opensuse.org/opensuse-security-announce/2015-06/msg00029.html http://lists.opensuse.org/opensuse-security-announce&#x • CWE-264: Permissions, Privileges, and Access Controls •

Xen 3.3.x through 4.5.x enables logging for PCI MSI-X pass-through error messages, which allows local x86 HVM guests to cause a denial of service (host disk consumption) via certain invalid operations. Xen 3.3.x hasta 4.5.x habilita el registro para mensajes de error 'pass-through' de PCI MSI-X, lo que permite a invitados locales de x86 HVM causar una denegación de servicio (consumo de disco de anfitrión) a través de ciertas operaciones inválidas. • http://lists.fedoraproject.org/pipermail/package-announce/2015-June/160154.html http://lists.fedoraproject.org/pipermail/package-announce/2015-June/160171.html http://lists.fedoraproject.org/pipermail/package-announce/2015-June/160685.html http://lists.opensuse.org/opensuse-security-announce/2015-06/msg00004.html http://lists.opensuse.org/opensuse-security-announce/2015-06/msg00007.html http://lists.opensuse.org/opensuse-security-announce/2015-06/msg00029.html http://lists.opensuse.org/opensuse-security-announce&#x • CWE-399: Resource Management Errors •
