Security Fix(es):

  * Quick Emulator(Qemu) built with the Block driver for iSCSI images support
(virtio-blk) is vulnerable to a heap buffer overflow issue. It could occur
while processing iSCSI asynchronous I/O ioctl(2) calls. A user inside guest
could use this flaw to crash the Qemu process resulting in DoS or
potentially leverage it to execute arbitrary code with privileges of the
Qemu process on the host. (CVE-2016-5126)

  * 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. (CVE-2016-5403)

Red Hat would like to thank hongzhenhao (Marvel Team) for reporting
CVE-2016-5403.");
