   An update that solves 12 vulnerabilities and has one errata
   is now available.

Description:


   This update for xen fixes several issues.

   These security issues were fixed:

   - 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-2017-2615: 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-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-2016-10013: Xen allowed local 64-bit x86 HVM guest OS users to gain
     privileges by leveraging mishandling of SYSCALL singlestep during
     emulation (bsc#1016340).
   - CVE-2016-9932: CMPXCHG8B emulation on x86 systems allowed local HVM
     guest OS users to obtain sensitive information from host stack memory
     via a "supposedly-ignored" operand size prefix (bsc#1012651).
   - 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)
   - CVE-2016-10024: Xen allowed local x86 PV guest OS kernel administrators     to cause a denial of service (host hang or crash) by modifying the
     instruction stream asynchronously while performing certain kernel
     operations (bsc#1014298)

   This non-security issue was fixed:

   - bsc#1002496: Added support for reloading clvm in block-dmmd block-dmmd
