https://notcve.org/view.php?id=CVE-2012-4544
The PV domain builder in Xen 4.2 and earlier does not validate the size of the kernel or ramdisk (1) before or (2) after decompression, which allows local guest administrators to cause a denial of service (domain 0 memory consumption) via a crafted (a) kernel or (b) ramdisk. El PV domain builder en Xen 4.2 y anteriores, no valida el tamaño del kernel o del ramdisk(1) antes o (2) después de la descompresión, lo que permite a administradores locales de los sistemas huésped provocar una denegación de servicio (consumo de memoria) a través de un (1)kernel o (2)ramdisk manipulado. • http://lists.fedoraproject.org/pipermail/package-announce/2012-November/091832.html http://lists.fedoraproject.org/pipermail/package-announce/2012-November/091844.html http://lists.fedoraproject.org/pipermail/package-announce/2012-November/092050.html http://lists.opensuse.org/opensuse-security-announce/2012-11/msg00008.html http://lists.opensuse.org/opensuse-security-announce/2012-11/msg00009.html http://lists.opensuse.org/opensuse-security-announce/2012-11/msg00017.html http://lists.opensuse.org/opensuse-security- • CWE-20: Improper Input Validation •
