DESCRIPTION
 OpenLDAP[1] is an LDAPv2 and LDAPv3 server available for several
 platforms.
 
 Thomas Fritz reported[3] a vulnerability in the ldap server which
 could be exploited by remote attackers to delete attributes from an
 object even if those attributes were protected by ACLs.
 
 Authenticated users (in openldap versions 2.0.8 up to 2.0.19) could
 issue a REPLACE command for an attribute where the new value is an
 empty one, thus effectively removing the attribute if allowed by the
 current schema, that is, if the attribute in question is not
 mandatory. In versions prior to 2.0.8, anonymous users could do this
 as well, regardless of ACLs protecting this attribute.
 
 The OpenLDAP project has released[2] a new version to address this
 vulnerability. OpenLDAP 1.2.x is not affected by this vulnerability,
 only the specified 2.0.x releases.
 


SOLUTION
 It is recommended that all OpenLDAP 2.0.x users upgrade their
 packages. If the service is already running, the upgrade will
 automatically restart it.
