Vulnerability Insight:
This update for qemu fixes the following issues:

Security issues fixed:

- CVE-2018-10839: Fixed NE2000 NIC emulation support that is vulnerable to
an integer overflow, which could lead to buffer overflow issue. It could
occur when receiving packets over the network. A user inside guest could
use this flaw to crash the Qemu process resulting in DoS (bsc#1110910).

- CVE-2018-15746: Fixed qemu-seccomp.c that might allow local OS guest
users to cause a denial of service (guest crash) by leveraging
mishandling of the seccomp policy for threads other than the main thread
(bsc#1106222).

- CVE-2018-16847: Fixed an OOB heap buffer r/w access issue that was found
in the NVM Express Controller emulation in QEMU. It could occur in
nvme_cmb_ops routines in nvme device. A guest user/process could use
this flaw to crash the QEMU process resulting in DoS or potentially run
arbitrary code with privileges of the QEMU process (bsc#1114529).

- CVE-2018-17958: Fixed a Buffer Overflow in rtl8139_do_receive in
hw/net/rtl8139.c because an incorrect integer data type is used
(bsc#1111006).

- CVE-2018-17962: Fixed a Buffer Overflow in pcnet_receive in
hw/net/pcnet.c because an incorrect integer data type is used
(bsc#1111010).

- CVE-2018-17963: Fixed qemu_deliver_packet_iov in net/net.c that accepts
packet sizes greater than INT_MAX, which allows attackers to cause a
denial of service or possibly have unspecified other impact.
(bsc#1111013)

- CVE-2018-18849: Fixed an out of bounds memory access issue that was
found in the LSI53C895A SCSI Host Bus Adapter emulation while writing a
message in lsi_do_msgin. It could occur during migration if the
'msg_len' field has an invalid value. A user/process could use this flaw
to crash the Qemu process resulting in DoS (bsc#1114422).

Non-security issues fixed:

- Fix slowness in arm32 emulation (bsc#1112499).

- In order to improve spectre mitigation for s390x, add a new feature in
the QEMU cpu model to provide the etoken cpu feature for guests
(bsc#1107489).
