-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - -------------------------------------------------------------------------- CONECTIVA LINUX SECURITY ANNOUNCEMENT - -------------------------------------------------------------------------- PACKAGE : openldap SUMMARY : DATE : 2002-01-28 12:17:00 ID : CLA-2002:459 RELEVANT RELEASES : 6.0, 7.0 - ------------------------------------------------------------------------- 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.
