Package        : pacemaker
Version        : 1.1.16-1+deb9u2
Debian Bug     : 974563

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

We recommend that you upgrade your pacemaker packages.
