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

  - CVE-2017-5973: A infinite loop while doing control     transfer in xhci_kick_epctx allowed privileged user     inside the guest to crash the host process resulting in     DoS (bsc#1025188)

  - 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#1024183)

  - 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#1024834)

  - 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#1024186)

  - 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#1024307)

  - 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-2014-8106: A heap-based buffer overflow in the     Cirrus VGA emulator allowed local guest users to execute     arbitrary code via vectors related to blit regions     (bsc#907805)

  - CVE-2017-5579: The 16550A UART serial device emulation     support 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#1022627)

  - 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#1014490)

  - 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#1014507)

  - 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#1015169)

  - 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#1015169)

  - CVE-2016-9101: A memory leak in hw/net/eepro100.c     allowed local guest OS administrators to cause a denial     of service (memory consumption and QEMU process crash)     by repeatedly unplugging an i8255x (PRO100) NIC device     (bsc#1013668)

  - 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#1013657)

  - A malicious guest could have, by frequently rebooting     over extended periods of time, run the host system out     of memory, resulting in a Denial of Service (DoS)     (bsc#1022871)

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