CVE-2018-16877
A flaw was found in the way pacemaker's client-server authentication was implemented. A local attacker could use this flaw, and combine it with other IPC weaknesses, to achieve local privilege escalation.
CVE-2018-16878
An insufficient verification inflicted preference of uncontrolled processes can lead to denial-of-service.
CVE-2020-25654
An ACL bypass flaw was found in pacemaker. 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, these problems have been fixed in version 1.1.24-0+deb9u1.
We recommend that you upgrade your pacemaker packages.
For the detailed security status of pacemaker please refer to its security tracker page at: [link moved to references]
Further information about Debian LTS security advisories, how to apply these updates to your system and frequently asked questions can be found at: [link moved to references]");
