Security Fix(es):

* Quick emulator (QEMU) built with the Cirrus CLGD 54xx VGA emulator
support is vulnerable to an out-of-bounds access issue. It could occur
while copying VGA data via bitblt copy in backward mode. A privileged user
inside a guest could use this flaw to crash the QEMU process resulting in
DoS or potentially execute arbitrary code on the host with privileges of
QEMU process on the host. (CVE-2017-2615)

* Quick emulator (QEMU) built with the Cirrus CLGD 54xx VGA Emulator
support is vulnerable to an out-of-bounds access issue. The issue could
occur while copying VGA data in cirrus_bitblt_cputovideo. A privileged user
inside guest could use this flaw to crash the QEMU process OR potentially
execute arbitrary code on host with privileges of the QEMU process.
(CVE-2017-2620)

Red Hat would like to thank Wjjzhang (Tencent.com Inc.) and Li Qiang
(360.cn Inc.) for reporting CVE-2017-2615.

Bug Fix(es):

* When using the virtio-blk driver on a guest virtual machine with no space
on the virtual hard drive, the guest terminated unexpectedly with a 'block
I/O error in device' message and the qemu-kvm process exited with a
segmentation fault. This update fixes how the system_reset QEMU signal is
handled in the above scenario. As a result, if a guest crashes due to no
space left on the device, qemu-kvm continues running and the guest can be
reset as expected. (BZ#1420049)
