CVE-2012-2934: Xen

Low severity, CVSS 1.9. EPSS: 0.4% chance of exploitation in the next 30 days.

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 products

• Xen Xen: version 4.0.0 only; version 4.1.0 only
