Mandriva Update for openldap MDVSA-2011:056 (openldap)

Solution
Please Install the Updated Packages.
Insight
Multiple vulnerabilities has been identified and fixed in openldap: chain.c in back-ldap in OpenLDAP 2.4.x before 2.4.24, when a master-slave configuration with a chain overlay and ppolicy_forward_updates (aka authentication-failure forwarding) is used, allows remote authenticated users to bypass external-program authentication by sending an invalid password to a slave server (CVE-2011-1024). bind.cpp in back-ndb in OpenLDAP 2.4.x before 2.4.24 does not require authentication for the root Distinguished Name (DN), which allows remote attackers to bypass intended access restrictions via an arbitrary password (CVE-2011-1025). modrdn.c in slapd in OpenLDAP 2.4.x before 2.4.24 allows remote attackers to cause a denial of service (daemon crash) via a relative Distinguished Name (DN) modification request (aka MODRDN operation) that contains an empty value for the OldDN field (CVE-2011-1081). The updated packages have been patched to correct these issues.
