NVD Description

Note: Versions mentioned in the description apply only to the upstream xen package and not the xen package as distributed by Echo. See How to fix? for Echo:latest relevant fixed versions and status.

Xen 3.2.x through 4.4.x does not properly clean memory pages recovered from guests, which allows local guest OS users to obtain sensitive information via unspecified vectors.
