1.9 LOW — AV:L/AC:M/Au:N/C:N/I:N/A:P

Description

Xen 4.0, and 4.1, when running a 64-bit PV guest on "older" AMD CPUs, does not properly protect against a certain AMD processor bug, which allows local guest OS users to cause a denial of service (host hang) via sequential execution of instructions across a non-canonical boundary, a different vulnerability than CVE-2012-0217.

Affected configurations

• xen xen 4.0.0 • xen xen 4.1.0
