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)

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