issue to execute arbitrary code with root privileges. (CVE-2016-7035)

Alain Moulle discovered that Pacemaker incorrectly handled
authentication. A remote attacker could possibly use this issue to
shut down connections, leading to a denial of service. This issue only
affected Ubuntu 16.04 LTS. (CVE-2016-7797).
