Descriptions

The (1) memc_save_get_next_page, (2) tmemc_restore_put_page and (3) tmemc_restore_flush_page functions in the Transcendent Memory (TMEM) in Xen 4.0, 4.1, and 4.2 do not check for negative id pools, which allows local guest OS users to cause a denial of service (memory corruption and host crash) or possibly execute arbitrary code via unspecified vectors. NOTE: this issue was originally published as part of CVE-2012-3497, which was too general; CVE-2012-3497 has been SPLIT into this ID and others.

Las funciones (1) memc_save_get_next_page, (2) tmemc_restore_put_page y (3) tmemc_restore_flush_page en el Transcendent Memory (TMEM) en Xen v4.0, v4.1, y v4.2 no comprueba los pools de id negativos, lo que permite a usuarios del SO de invitado provocar una denegación de servicio (corrupción de memoria y caída del host) o posiblemente ejecutar código arbitrario a través de vectores no especificados. NOTA: este problema se publicó originalmente como parte de CVE-2012-3497, que era demasiado general; CVE-2012-3497 se ha dividido en este ID y otros.
