   An update that solves 6 vulnerabilities and has two fixes
   is now available.

Description:

   This update for xen fixes several issues.

   These security issues were fixed:

   - CVE-2017-12135: Unbounded recursion in grant table code allowed a
     malicious guest to crash the host or potentially escalate
     privileges/leak information (XSA-226, bsc#1051787).
   - CVE-2017-12137: Incorrectly-aligned updates to pagetables allowed for
     privilege escalation (XSA-227, bsc#1051788).
   - CVE-2017-11434: The dhcp_decode function in slirp/bootp.c allowed local
     guest OS users to cause a denial of service (out-of-bounds read) via a
     crafted DHCP
     options string (bsc#1049578).
   - CVE-2017-10664: qemu-nbd did not ignore SIGPIPE, which allowed remote
     attackers to cause a denial of service (daemon crash) by disconnecting
     during a server-to-client reply attempt (bsc#1046637).
   - CVE-2017-11334: The address_space_write_continue function in exec.c
     allowed local guest OS privileged users to cause a denial of service
     (out-of-bounds access and guest instance crash) by leveraging use of
     qemu_map_ram_ptr to access guest ram block area (bsc#1048920).
   - CVE-2017-10806: Stack-based buffer overflow in hw/usb/redirect.c allowed
     local guest OS users to cause a denial of service via vectors related to
     logging debug messages (bsc#1047675).
   - bsc#1052686: Premature clearing of GTF_writing / GTF_reading lead to
     potentially leaking sensitive information (XSA-230).

   This non-security issue was fixed:

   - bsc#1002573: Optimized LVM functions in block-dmmd block-dmmd
