"This update for qemu fixes several issues. These security issues were
fixed :

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

  - CVE-2017-5857: The Virtio GPU Device emulator support
    was vulnerable to a host memory leakage issue allowing a
    guest user to leak host memory resulting in DoS
    (bsc#1023073).

  - 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-2016-9921: 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-2016-10029: The Virtio GPU Device emulator support
    was vulnerable to an OOB read issue allowing a guest
    user to crash the Qemu process instance resulting in Dos
    (bsc#1017081).

  - CVE-2016-10028: The Virtio GPU Device emulator support
    was vulnerable to an out of bounds memory access issue
    allowing a guest user to crash the Qemu process instance
    on a host, resulting in DoS (bsc#1017084).

  - 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-2017-5552: The Virtio GPU Device emulator support
    was vulnerable to a memory leakage issue allowing a
    guest user to leak host memory resulting in DoS
    (bsc#1021195).

  - CVE-2017-5578: The Virtio GPU Device emulator support
    was vulnerable to a memory leakage issue allowing a
    guest user to leak host memory resulting in DoS
    (bsc#1021481).

  - 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)

The update package also includes non-security fixes. See advisory for
details.
