Synopsis :

The remote openSUSE host is missing a security update.

Description :

The XEN hypervisor was updated to fix two security issues :

- Fixed a buffer overflow in the floppy drive emulation,
which could be used to denial of service attacks or
potential code execution against the host.
(CVE-2015-3456)

- Xen did not initialize certain fields, which allowed
certain remote service domains to obtain sensitive
information from memory via a (1) XEN_DOMCTL_gettscinfo
or (2) XEN_SYSCTL_getdomaininfolist request.
(CVE-2015-3340)
