"According to its version, the installation of IBM Tivoli Directory
Server on the remote host is prior to 6.1.0.47 / 6.2.0.22 / 6.3.0.11. 
It is, therefore, affected by one or more of the following
vulnerabilities :

  - A custom LDAP client can be created which causes IBM 
    Tivoli Directory Server to crash by sending a malformed
    paged search request. (IO15707, IO16001, IO16002)

  - In the default Tivoli Directory Server environment, with
    TLS enabled, the NULL-MD5, and NULL-SHA ciphers are
    enabled by default. (IO16035, IO16036, IOO15761)");
