"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)
