DESCRIPTION:
Some weaknesses and a security issue have been reported in Citrix
XenServer, which can be exploited by malicious, local users in a
guest virtual machine to cause a DoS (Denial of Service) and by
malicious, local users to disclose sensitive information.

normal operation of the hypervisor. No further information is
currently available.

Successful exploitation of this vulnerability requires administrative
privileges on a guest operating system.
