CVE-2012-0218

Description

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.

Affected packages (1)

• Debian/xenfrom 0, < 4.1.3~rc1+hg-20120614.a9c0a89c08f2-1
