CVE-2013-4494 – kernel: xen: Lock order reversal between page allocation and grant table locks

https://notcve.org/view.php?id=CVE-2013-4494

Xen before 4.1.x, 4.2.x, and 4.3.x does not take the page_alloc_lock and grant_table.lock in the same order, which allows local guest administrators with access to multiple vcpus to cause a denial of service (host deadlock) via unspecified vectors. Xen con versiones enteriores a 4.1.x, 4.2.x, 4.3.x, y no toma la page_alloc_lock grant_table.lock en el mismo orden, lo que permite a los administradores invitados locales con acceso a múltiples vcpus causar una denegación de servicio (bloqueo host) a través sin especificar vectores. • http://lists.opensuse.org/opensuse-security-announce/2014-03/msg00015.html http://lists.opensuse.org/opensuse-security-announce/2014-03/msg00021.html http://lists.opensuse.org/opensuse-security-announce/2014-04/msg00000.html http://lists.opensuse.org/opensuse-updates/2013-12/msg00059.html http://rhn.redhat.com/errata/RHSA-2014-0108.html http://security.gentoo.org/glsa/glsa-201407-03.xml http://www.debian.org/security/2014/dsa-3006 http://www.openwall.com/lists/oss-security/2013/11 • CWE-20: Improper Input Validation •
