Security database references:
In the Debian bugtracking system: Bug 974563.
More information:

The update of pacemaker released as DLA-2447-1 caused a regression when the communication between the Corosync cluster engine and pacemaker takes place. A permission problem prevents IPC requests between cluster nodes. The patch for CVE-2020-25654 has been reverted until a better solution can be found.

For Debian 9 stretch, this problem has been fixed in version 1.1.16-1+deb9u2.

We recommend that you upgrade your pacemaker packages.
