Package : pacemaker
Version : 1.1.24-0+deb9u1
CVE ID : CVE-2018-16877 CVE-2018-16878 CVE-2020-25654
Several security vulnerabilities were addressed in pacemaker, a cluster
resource manager.
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.
