https://notcve.org/view.php?id=CVE-2007-6207
Xen 3.x, possibly before 3.1.2, when running on IA64 systems, does not check the RID value for mov_to_rr, which allows a VTi domain to read memory of other domains. Xen 3.x, posiblemente versiones anteriores a 3.1.2, ejecutándose en sistemas IA64, no comprueba el valor RID de mov_to_rr, lo cual permite a un dominio VTi leer memoria de otros dominios. • http://lists.xensource.com/archives/html/xen-announce/2007-11/msg00000.html http://lists.xensource.com/archives/html/xen-ia64-devel/2007-10/msg00189.html http://osvdb.org/41341 http://secunia.com/advisories/27915 http://secunia.com/advisories/29236 http://www.redhat.com/support/errata/RHSA-2008-0154.html http://www.securityfocus.com/bid/26716 https://oval.cisecurity.org/repository/search/definition/oval%3Aorg.mitre.oval%3Adef%3A9471 https://access.redhat.com/security/cve/CVE-200 • CWE-20: Improper Input Validation •
