"This update for qemu fixes several issues.

These security issues were fixed :

  - CVE-2017-2620: In CIRRUS_BLTMODE_MEMSYSSRC mode the
    bitblit copy routine cirrus_bitblt_cputovideo failed to
    check the memory region, allowing for an out-of-bounds
    write that allows for privilege escalation (bsc#1024972)

  - CVE-2017-2615: An error in the bitblt copy operation
    could have allowed a malicious guest administrator to
    cause an out of bounds memory access, possibly leading
    to information disclosure or privilege escalation
    (bsc#1023004)

  - CVE-2017-5856: The MegaRAID SAS 8708EM2 Host Bus Adapter
    emulation support was vulnerable to a memory leakage
    issue allowing a privileged user to leak host memory
    resulting in DoS (bsc#1023053)

  - CVE-2016-9776: The ColdFire Fast Ethernet Controller
    emulator support was vulnerable to an infinite loop
    issue while receiving packets in 'mcf_fec_receive'. A
    privileged user/process inside guest could have used
    this issue to crash the Qemu process on the host leading
    to DoS (bsc#1013285)

  - CVE-2016-9911: The USB EHCI Emulation support was
    vulnerable to a memory leakage issue while processing
    packet data in 'ehci_init_transfer'. A guest
    user/process could have used this issue to leak host
    memory, resulting in DoS for the host (bsc#1014111)

  - CVE-2016-9907: The USB redirector usb-guest support was
    vulnerable to a memory leakage flaw when destroying the
    USB redirector in 'usbredir_handle_destroy'. A guest
    user/process could have used this issue to leak host
    memory, resulting in DoS for a host (bsc#1014109)

  - CVE-2016-9921: The Cirrus CLGD 54xx VGA Emulator support
    was vulnerable to a divide by zero issue while copying
    VGA data. A privileged user inside guest could have used
    this flaw to crash the process instance on the host,
    resulting in DoS (bsc#1014702)

  - CVE-2016-9922: The Cirrus CLGD 54xx VGA Emulator support
    was vulnerable to a divide by zero issue while copying
    VGA data. A privileged user inside guest could have used
    this flaw to crash the process instance on the host,
    resulting in DoS (bsc#1014702)

  - CVE-2016-10155: The virtual hardware watchdog
    'wdt_i6300esb' was vulnerable to a memory leakage issue
    allowing a privileged user to cause a DoS and/or
    potentially crash the Qemu process on the host
    (bsc#1021129)

  - CVE-2017-5526: The ES1370 audio device emulation support
    was vulnerable to a memory leakage issue allowing a
    privileged user inside the guest to cause a DoS and/or
    potentially crash the Qemu process on the host
    (bsc#1020589)

  - CVE-2017-5525: The ac97 audio device emulation support
    was vulnerable to a memory leakage issue allowing a
    privileged user inside the guest to cause a DoS and/or
    potentially crash the Qemu process on the host
    (bsc#1020491)

  - CVE-2017-5667: The SDHCI device emulation support was
    vulnerable to an OOB heap access issue allowing a
    privileged user inside the guest to crash the Qemu
    process resulting in DoS or potentially execute
    arbitrary code with privileges of the Qemu process on
    the host (bsc#1022541)

  - CVE-2017-5898: The CCID Card device emulator support was
    vulnerable to an integer overflow allowing a privileged
    user inside the guest to crash the Qemu process
    resulting in DoS (bnc#1023907)

These non-security issues were fixed :

  - Fix post script for qemu-guest-agent rpm to actually
    activate the guest agent at rpm install time

  - Fixed various inaccuracies in cirrus vga device
    emulation

  - Fixed cause of infrequent migration failures from bad
    virtio device state (bsc#1020928)

  - Fixed virtio interface failure (bsc#1015048)

  - Fixed graphical update errors introduced by previous
    security fix (bsc#1016779)

  - Fixed uint64 property parsing and add regression tests
    (bsc#937125)
