Descriptions
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.
Multiple vulnerabilities have been found in Xen, allowing attackers on a Xen Virtual Machine to execute arbitrary code, cause Denial of Service, or gain access to data on the host. Versions less than 4.2.2-r1 are affected.
