Summary
Security update for xen
Details

This update for xen fixes several issues.

These security issues were fixed:

  • CVE-2017-14316: Missing bound check in function alloc_heap_pages for an internal array allowed attackers using crafted hypercalls to execute arbitrary code within Xen (XSA-231, bsc#1056278)
  • CVE-2017-14318: The function _gnttabcache_flush missed a check for grant tables, allowing a malicious guest to crash the host or for x86 PV guests to potentially escalate privileges (XSA-232, bsc#1056280)
  • CVE-2017-14317: A race in cxenstored may have cause a double-free allowind for DoS of the xenstored daemon (XSA-233, bsc#1056281).
  • CVE-2017-14319: An error while handling grant mappings allowed malicious or buggy x86 PV guest to escalate its privileges or crash the hypervisor (XSA-234, bsc#1056282).
