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
