A number of security vulnerabilities have been
identified in Citrix XenServer that could, in certain configurations, allow a
malicious administrator of a guest VM to compromise the host or obtain potentially
sensitive information from other guest VMs. In addition, a vulnerability has been
identified that would allow certain applications running on a guest to cause that guest to crash.
