This update for xen fixes several issues.

These security issues were fixed:

  • bsc#1068187: Failure to recognize errors in the Populate on Demand (PoD)
    code allowed for DoS (XSA-246)
  • bsc#1068191: Missing p2m error checking in PoD code allowed unprivileged
    guests to retain a writable mapping of freed memory leading to
    information leaks, privilege escalation or DoS (XSA-247).
  • CVE-2017-15289: The mode4and5 write functions allowed local OS guest
    privileged users to cause a denial of service (out-of-bounds write
    access and Qemu process crash) via vectors related to dst calculation
    (bsc#1063123)
  • CVE-2017-15597: A grant copy operation being done on a grant of a dying
    domain allowed a malicious guest administrator to corrupt hypervisor
    memory, allowing for DoS or potentially privilege escalation and
    information leaks (bsc#1061075).
  • CVE-2017-15595: x86 PV guest OS users were able to cause a DoS
    (unbounded recursion, stack consumption, and hypervisor crash) or
    possibly gain privileges via crafted page-table stacking (bsc#1061081).
  • CVE-2017-15592: x86 HVM guest OS users were able to cause a DoS
    (hypervisor crash) or possibly gain privileges because self-linear
    shadow mappings were mishandled for translated guests (bsc#1061086).
