       An update that fixes 6 vulnerabilities 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).
