  <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-2017-12136: Race conditions with maptrack free list handling allows a
  malicious guest administrator to crash the host or escalate their privilege to
  that of the host (XSA-228, bsc#1051789).
- 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-2017-12855: Premature clearing of GTF_writing / GTF_reading lead to
  potentially leaking sensitive information (XSA-230 bsc#1052686.

These non-security issues were fixed:

- bsc#1055695: XEN: 11SP4 and 12SP3 HVM guests can not be restored after the save using xl stack
- bsc#1035231: Migration of HVM domU did not use superpages on destination dom0
- bsc#1002573: Optimized LVM functions in block-dmmd block-dmmd
