An attacker having a local account on the cluster and in the haclient group could use IPC communication with various daemons directly to perform certain tasks that they would be prevented by ACLs from doing if they went through the configuration. For Debian 9 stretch, this problem has been fixed in version 1.1.16-1+deb9u1. We recommend that you upgrade your pacemaker packages. For the detailed security status of pacemaker please refer to its security tracker page at: https://security-tracker.debian.org/tracker/pacemaker Further information about Debian LTS security advisories, how to apply these updates to your system and frequently asked questions can be found at: https://wiki.debian.org/LTS
