Message-ID: <200307042239.TAA18528@frajuto.distro.conectiva> Date: Fri, 4 Jul 2003 19:39:00 -0300 From: Conectiva Updates <secure@...ectiva.com.br> To: conectiva-updates@...aleguas.conectiva.com.br, lwn@....net, bugtraq@...urityfocus.com, security-alerts@...uxsecurity.com, linsec@...ts.seifried.org Subject: [CLA-2003:685] Conectiva Security Announcement - openldap -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - -------------------------------------------------------------------------- CONECTIVA LINUX SECURITY ANNOUNCEMENT - -------------------------------------------------------------------------- PACKAGE : openldap SUMMARY : Denial of Service and other (non-security) fixes DATE : 2003-07-04 19:34:00 ID : CLA-2003:685 RELEVANT RELEASES : 9 - ------------------------------------------------------------------------- DESCRIPTION OpenLDAP[1] is an LDAPv2 and LDAPv3 server available for several platforms. This update addresses the following issues in the OpenLDAP package shipped with Conectiva Linux 9: 1) Denial of Service vulnerability[2] A failed password extended operation (password EXOP) can cause openldap to, if using the back-ldbm backend, attempt to free memory which was never allocated, resulting in a segfault. The back-bdb backend, on the other hand, has a memory leak in the same code. Both conditions can be triggered remotely. 2) Crypt and md5 hash support[3] The OpenLDAP packages shipped with Conectiva Linux 9 do not have support for crypt and md5 password hashes. As a result, users migrated to LDAP from system password files will not be able to authenticate against the directory using simple binds. 3) One shot replication mode does not work[4] The slurpd program shipped with OpenLDAP is responsible for replicating data from a master OpenLDAP server to slave servers. It has a replication mode called "one shot" which takes a replication log file and attempts to replicate all changes to the specified slaves and then exits. This mode was not working in openldap-2.1.16, which is the version originally shipped with Conectiva Linux 9. This announcement updates OpenLDAP for Conectiva Linux 9 to version 2.1.21, which, besides containing the fixes above and several others, also includes many other improvements in indexes and performance. SOLUTION It is recommended that all OpenLDAP users in Conectiva Linux 9 update their packages. After the upgrade, the slapd service will be automatically restarted if it was already running.
