Synopsis: Important: qemu-kvm security update
Advisory ID: SLSA-2015:0998-1
Issue Date: 2015-05-13
CVE Numbers: CVE-2015-3456
--

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 this update, shut down all running virtual machines. Once
all virtual machines have shut down, start them again for this update to
take effect.
