Security update for xen

This update for xen fixes several issues.

These security issues were fixed:

  • CVE-2018-8897: Prevent mishandling of debug exceptions on x86 (XSA-260, bsc#1090820)
  • Handle HPET timers in IO-APIC mode correctly to prevent malicious or buggy HVM guests from causing a hypervisor crash or potentially privilege escalation/information leaks (XSA-261, bsc#1090822)
  • Prevent unbounded loop, induced by qemu allowing an attacker to permanently keep a physical CPU core busy (XSA-262, bsc#1090823)
  • CVE-2018-10472: x86 HVM guest OS users (in certain configurations) were able to read arbitrary dom0 files via QMP live insertion of a CDROM, in conjunction with specifying the target file as the backing file of a snapshot (bsc#1089152).
  • CVE-2018-10471: x86 PV guest OS users were able to cause a denial of service (out-of-bounds zero write and hypervisor crash) via unexpected INT 80 processing, because of an incorrect fix for CVE-2017-5754 (bsc#1089635).

These non-security issues were fixed:

  • bsc#1086039: Ensure that Dom0 does represent DomU cpu flags correctly
  • bsc#1027519: Fixed shadow mode guests
