Security Fix(es):

  * A heap buffer overflow flaw was found in QEMU's Cirrus CLGD 54xx VGA
emulator's VNC display driver support  the issue could occur when a VNC
client attempted to update its display after a VGA operation is performed
by a guest. A privileged user/process 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-2016-9603)

  * 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 memory access issue was found in QEMU's VNC display
driver support. The vulnerability could occur while refreshing the VNC
display surface area in the 'vnc_refresh_server_surface'. A user/process
inside a guest could use this flaw to crash the QEMU process, resulting in
a denial of service. (CVE-2017-2633)

  * 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)
