Synopsis
The remote Xen hypervisor installation is missing a security update.
Description
According to its self-reported version number, the Xen hypervisor installed on the remote host is affected by a vulnerability allowing a guest system to potentially elevate privileges, access protected information, and perform a DoS against the host. A number of caveats exist to determine if a system is vulnerable. Please refer to the vendor advisory for more information.
Note that Nessus has checked the changeset versions based on the xen.git change log. Nessus did not check guest hardware configurations or if patches were applied manually to the source code before a recompile and reinstall.
Solution
Apply the appropriate patch according to the vendor advisory.
