Improper Handling of Insufficient Privileges vulnerability in Apache Accumulo.

An authenticated, but low-privileged user without system permissions may

issue a remote command to gracefully shutdown system components

(compaction-coordinator, compactor, gc, manager, monitor, tserver, or sserver),

leading to a denial of service.

This issue affects Apache Accumulo 2.1.4 and 2.1.5.

Users are recommended to upgrade to version 2.1.6, which fixes the issue.
