Security Fix(es):

  * An out-of-bounds read-access flaw was found in the QEMU emulator built
with IP checksum routines. The flaw could occur when computing a TCP/UDP
packet's checksum, because a QEMU function used the packet's payload length
without checking against the data buffer's size. A user inside a guest
could use this flaw to crash the QEMU process (denial of service).
(CVE-2016-2857)

Red Hat would like to thank Ling Liu (Qihoo 360 Inc.) for reporting this
issue.

Bug Fix(es):

  * Previously, rebooting a guest virtual machine more than 128 times in a
short period of time caused the guest to shut down instead of rebooting,
because the virtqueue was not cleaned properly. This update ensures that
the virtqueue is cleaned more reliably, which prevents the described
problem from occurring. (BZ#1393484)");
