https://notcve.org/view.php?id=CVE-2014-1892

Xen 3.3 through 4.1, when XSM is enabled, allows local users to cause a denial of service via vectors related to a "large memory allocation," a different vulnerability than CVE-2014-1891, CVE-2014-1893, and CVE-2014-1894.

CVE-2013-4554 – kernel: xen: hypercalls exposed to privilege rings 1 and 2 of HVM guests

https://notcve.org/view.php?id=CVE-2013-4554

Xen 3.0.3 through 4.1.x (possibly 4.1.6.1), 4.2.x (possibly 4.2.3), and 4.3.x (possibly 4.3.1) does not properly prevent access to hypercalls, which allows local guest users to gain privileges via a crafted application running in ring 1 or 2. Xen 3.0.3 a 4.1.x (posiblemente 4.1.6.1), 4.2.x (posiblemente 4.2.3), y 4.3.x (posiblemente 4.3.1) no previene correctamente acceso a hypercalls, lo cual permite a usuarios invitados locales obtener privilegios a través de la ejecución de una aplicación manipulada en el anillo 1 o el anillo 2. • http://lists.opensuse.org/opensuse-security-announce/2014-03/msg00010.html 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-2014-0285.html http://security.gentoo.org/glsa/glsa-201407-03.xml http://www.openwall.com/lists&# • CWE-264: Permissions, Privileges, and Access Controls •

CVE-2013-4553

https://notcve.org/view.php?id=CVE-2013-4553

The XEN_DOMCTL_getmemlist hypercall in Xen 3.4.x through 4.3.x (possibly 4.3.1) does not always obtain the page_alloc_lock and mm_rwlock in the same order, which allows local guest administrators to cause a denial of service (host deadlock). La hypercall XEN_DOMCTL_getmemlist en Xen 3.4.x a 4.3.x (posiblemente 4.3.1) no obtiene siempre los bloqueos page_alloc_lock y mm_rwlock en el mismo orden, lo cual permite a administradores locales invitados causar denegación de servicio (bloqueo del host). • http://lists.opensuse.org/opensuse-security-announce/2014-03/msg00010.html http://lists.opensuse.org/opensuse-security-announce/2014-03/msg00021.html http://lists.opensuse.org/opensuse-updates/2013-12/msg00059.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/2013/11/26/8 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
