Vulnerability Name:

CVE-2012-0218 (CCN-76227)

Assigned:2011-12-14
Published:2012-06-12
Updated:2013-10-11
Summary:Xen 3.4, 4.0, and 4.1, when the guest OS has not registered a handler for a syscall or sysenter instruction, does not properly clear a flag for exception injection when injecting a General Protection Fault, which allows local PV guest OS users to cause a denial of service (guest crash) by later triggering an exception that would normally be handled within Xen.
