NVD Description

Note: Versions mentioned in the description apply only to the upstream postgresql-pltcl package and not the postgresql-pltcl package as distributed by Oracle. See How to fix? for Oracle:8 relevant fixed versions and status.

A flaw was found in PostgreSQL's "ALTER ... DEPENDS ON EXTENSION", where sub-commands did not perform authorization checks. An authenticated attacker could use this flaw in certain configurations to perform drop objects such as function, triggers, et al., leading to database corruption. This issue affects PostgreSQL versions before 12.2, before 11.7, before 10.12 and before 9.6.17.
