The pg_ctlcluster script in postgresql-common in versions prior to 210 didnt drop privileges when creating socket/statistics temporary directories, which could result in local privilege escalation.
Weakness
The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor.
