Detailed description of the issue:
A pair of design-level security vulnerabilities were discovered, verging on mere weaknesses in isolation, but when opportunistically combined, making for a local privilege escalation (which is easily extended to taking control over the whole cluster, which is a natural consequence of obtaining local root privileges solely by the means of what pacemaker unexpectedly allows one to breach on its own -- note that
