1.9 LOW — AV:L/AC:M/Au:N/C:N/I:N/A:P

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 configurations

• xen xen 3.4.0 • xen xen 4.0.0 • xen xen 4.1.0
