Caldera International, Inc. Security Advisory

Subject: Linux - OpenLDAP attribute deletion problem
Advisory number: CSSA-2002-001.0
Issue date: 2002, January 16
Cross reference:
______________________________________________________________________________

1. Problem Description

   Recently a security flaw was discovered in OpenLDAP 2.0.19 slapd(8)
   regarding application of access controls upon modify operations issued
   by authenticated users. Specifically, slapd(8) did not disallow a
   replace with no values from deleting the attribute which was protected
   by ACLs (if such was allowed by checked schema rules). That is, this
   flaw allowed any authenticated user to delete any non-mandatory
   attribute of an object. In 2.0 versions prior to 2.0.8, this flaw is
   NOT restricted to authenticated users (that is, anonymous users can
   abuse the flaw as well).
