The remote SUSE host is missing one or more security updates.
The Virtualization service XEN was updated to fix various bugs and
The following security issues have been fixed :
XSA-125: Long latency MMIO mapping operations were not preemptible.
CVE-2015-2151: XSA-123: Instructions with register operands ignored
eventual segment overrides encoded for them. Due to an insufficiently
conditional assignment such a bogus segment override could have,
however, corrupted a pointer used subsequently to store the result of
CVE-2015-2045: XSA-122: The code handling certain sub-operations of
the HYPERVISOR_xen_version hypercall failed to fully initialize all
fields of structures subsequently copied back to guest memory. Due to
this hypervisor stack contents were copied into the destination of the
operation, thus becoming visible to the guest.
CVE-2015-2044: XSA-121: Emulation routines in the hypervisor dealing
with certain system devices checked whether the access size by the
guest is a supported one. When the access size is unsupported these
routines failed to set the data to be returned to the guest for read
accesses, so that hypervisor stack contents were copied into the
destination of the operation, thus becoming visible to the guest.
Note that Tenable Network Security has extracted the preceding
description block directly from the SUSE security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.
