  script_tag(name:"insight", value:"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)

  This update was imported from the SUSE:SLE-12-SP3:Update update project.
