Synopsis: Moderate: qemu-kvm security update
Advisory ID: SLSA-2016:1585-1
Issue Date: 2016-08-09
CVE Numbers: CVE-2016-5403
--

Security Fix(es):

* Quick emulator(Qemu) built with the virtio framework is vulnerable to an
unbounded memory allocation issue. It was found that a malicious guest
user could submit more requests than the virtqueue size permits.
Processing a request allocates a VirtQueueElement and therefore causes
unbounded memory allocation on the host controlled by the guest.
