| Description: | OpenLDAP is an open source suite of LDAP (Lightweight Directory Access Protocol) applications and development tools.
The nss_ldap module is an extension for use with GNU libc which allows applications to, without internal modification, consult a directory service using LDAP to supplement information that would be read from local files such as /etc/passwd, /etc/group, and /etc/shadow.
A bug was found in the way OpenLDAP, nss_ldap, and pam_ldap refer LDAP servers. If a client connection is referred to a different server, it is possible that the referred connection will not be encrypted even if the client has "ssl start_tls" in its ldap.conf file. The Common Vulnerabilities and Exposures project has assigned the name CAN-2005-2069 to this issue.
A bug was also found in the way certain OpenLDAP authentication schemes store hashed passwords. A remote attacker could re-use a hashed password to gain access to unauthorized resources. The Common Vulnerabilities and Exposures project has assigned the name CAN-2004-0823 to this issue.
All users of OpenLDAP and nss_ldap are advised to upgrade to these updated packages, which contain backported fixes that resolve these issues.
