Summary
Various vulnerabilities were discovered in PostgreSQL: CVE-2014-0060 Shore up GRANT ... WITH ADMIN OPTION restrictions (Noah Misch) Granting a role without ADMIN OPTION is supposed to prevent the grantee from adding or removing members from the granted role, but this restriction was easily bypassed by doing SET ROLE first. The security impact is mostly that a role member can revoke the access of others, contrary to the wishes of his grantor. Unapproved role member additions are a lesser concern, since an uncooperative role member could provide most of his rights to others anyway by creating views or SECURITY DEFINER functions. Description truncated. Please see the references for more information.
