Security Fix(es):

  * An out-of-bounds r/w access issue was found in QEMU's Cirrus CLGD 54xx
VGA Emulator support. The vulnerability could occur while copying VGA data
via various bitblt functions. A privileged user inside a guest could use
this flaw to crash the QEMU process or, potentially, execute arbitrary code
on the host with privileges of the QEMU process. (CVE-2017-7980)

  * An out-of-bounds access issue was found in QEMU's Cirrus CLGD 54xx VGA
Emulator support. The vulnerability could occur while copying VGA data
using bitblt functions (for example, cirrus_bitblt_rop_fwd_transp_). A
privileged user inside a guest could use this flaw to crash the QEMU
process, resulting in denial of service. (CVE-2017-7718)

Red Hat would like to thank Jiangxin (PSIRT Huawei Inc) and Li Qiang (Qihoo
360 Gear Team) for reporting CVE-2017-7980 and Jiangxin (PSIRT Huawei Inc)
for reporting CVE-2017-7718.

Bug Fix(es):

  * Previously, guest virtual machines in some cases became unresponsive when
the 'pty' back end of a serial device performed an irregular I/O
communication. This update improves the handling of serial I/O on guests,
which prevents the described problem from occurring. (BZ#1452332)");
