NVD Description

Note: Versions mentioned in the description apply only to the upstream postgresql-docs package and not the postgresql-docs package as distributed by RHEL. See How to fix? for RHEL:6 relevant fixed versions and status.

CREATE TRIGGER in PostgreSQL 8.3.x before 8.3.18, 8.4.x before 8.4.11, 9.0.x before 9.0.7, and 9.1.x before 9.1.3 does not properly check the execute permission for trigger functions marked SECURITY DEFINER, which allows remote authenticated users to execute otherwise restricted triggers on arbitrary data by installing the trigger on an attacker-owned table.
