full virtualization solution for Linux on x86 hardware. Using KVM, one can run
multiple virtual machines running unmodified Linux or Windows images. Each
virtual machine has private virtualized hardware: a network card, disk,
graphics adapter, etc.

Security Fix(es):

  * An out-of-bounds read/write access flaw was found in the way QEMU's VGA
emulation with VESA BIOS Extensions (VBE) support performed read/write
operations using I/O port methods. A privileged guest user could use this
flaw to execute arbitrary code on the host with the privileges of the
host's QEMU process. (CVE-2016-3710)

  * 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 results in unbounded memory allocation
on the host controlled by the guest. (CVE-2016-5403)

Red Hat would like to thank Wei Xiao (360 Marvel Team) and Qinghao Tang
(360 Marvel Team) for reporting CVE-2016-3710 and hongzhenhao (Marvel Team)
