Synopsis :

The remote Scientific Linux host is missing one or more security
updates.

Description :

An out-of-bounds memory access flaw was found in the way QEMU's
virtual Floppy Disk Controller (FDC) handled FIFO buffer access while
processing certain FDC commands. A privileged guest user could use
this flaw to crash the guest or, potentially, execute arbitrary code
on the host with the privileges of the host's QEMU process
corresponding to the guest. (CVE-2015-3456)

After installing the updated packages, all running fully-virtualized
guests must be restarted for this update to take effect.
