SynopsisThe remote Xen hypervisor installation is missing a security update.
DescriptionAccording to its self-reported version number, the Xen hypervisor installed on the remote host is affected by an unspecified flaw in mm/shadow/multi.c that is triggered during the handling of self-linear shadow mappings with translated guests. This may allow an attacker on the guest to cause a denial of service or gain elevated privileges on the host.
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.
SolutionApply the appropriate patch according to the vendor advisory.
