Advisory ID: SLSA-2016:0082-1
Issue Date: 2016-01-28
CVE Numbers: CVE-2016-1714
--

An out-of-bounds read/write flaw was discovered in the way QEMU's Firmware
Configuration device emulation processed certain firmware configurations.
A privileged (CAP_SYS_RAWIO) guest user could use this flaw to crash the
QEMU process instance or, potentially, execute arbitrary code on the host
with privileges of the QEMU process. (CVE-2016-1714)

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.
