Debian LTS Advisory DLA-2447-1 [email protected]

Package : pacemaker
Version : 1.1.16-1+deb9u1
CVE ID : CVE-2020-25654
Debian Bug : 973254

An ACL bypass flaw was found in pacemaker, a cluster resource manager.
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:
