   An update that solves 6 vulnerabilities and has one errata
   is now available.

Description:

   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-2018-17958: 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:

   - Improving disk performance for qemu on xen (bsc#1100408)
