Summary
A vulnerability has been identified in Citrix XenServer which could, if exploited, allow a malicious administrator of an HVM guest VM to obtain meta-data about their own VM. Citrix is presently unaware of any meta-data that might be leaked that would be of value to a malicious guest administrator. In non-default configurations, where the RTL8139 guest network device has been configured to enable offload and the Citrix PV guest drivers are not active, it may also be possible for a remote attacker to obtain information from the HVM guest.
