   An update that solves 13 vulnerabilities and has four fixes
   is now available.

Description:


   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)
