Name of the Vulnerable Software and Affected Versions Xen versions 4.1.x through 4.4.x

Description The issue allows local guest administrators to cause a denial of service by consuming CPU resources. This is achieved by leveraging access to certain service domains for HVM guests and providing a large input to the HVMOP set mem access HVM control operations.

Recommendations For Xen versions 4.1.x through 4.4.x, consider restricting access to the HVMOP set mem access HVM control operations to prevent local guest administrators from causing a denial of service. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
