The problem can be corrected by upgrading your system to the following package versions:

Ubuntu 5.10:
libldap-2.2-7 2.2.26-3ubuntu0.2

Ubuntu 6.06 LTS:
libldap-2.2-7 2.2.26-5ubuntu2.2

Evgeny Legerov discovered that the OpenLDAP libraries did not correctly truncate authcid names. This situation would trigger an assert and abort the program using the libraries. A remote attacker could send specially crafted bind requests that would lead to an LDAP server denial of service.
