=== Security updates

* An uncontrolled recursion vulnerability that could lead to a
denial of service attack was identified in the {es} Grok parser.
A user with the ability to submit arbitrary queries to {es} could create
a malicious Grok query that will crash the {es} node.
All versions of {es} prior to 6.8.17 are affected by this flaw.
You must upgrade to {es} version 6.8.17 to obtain the fix.
