(OpenLDAP DoS Vulnerability)

    A password extended operation (password EXOP) which fails will cause
    the slapd server to free() an uninitialized pointer, possibly resulting
    in a segfault. This only affects servers using the back-ldbm backend.
    Such a crash is not guaranteed with every failed operation, however, it
    is possible.
  
Impact :

    An attacker (or indeed, a normal user) may crash the OpenLDAP server,
    creating a Denial of Service condition.
  
Workaround :

    A workaround is not currently known for this issue. All users are
    advised to upgrade to the latest version of the affected package."
