Description Jan Lieskovsky 2012-02-24 15:43:16 UTC
An absent permission check flaw was found in the way PostgreSQL performed creation of triggers (CREATE TRIGGER clause), defined to execute function by trigger invocation. An unprivileged database user could use this flaw to associate trigger function of their choose to their own table and thus cause such function to be called on the data of their choosing, even when that function had previously revoked access privileges to the attacker's PostgreSQL role.
