The installed version of eDirectory is affected by an integer overflow
issue in ds.dlm / dhost.exe (bound by default to TCP port 524) as well
as a heap-based buffer overflow that can be triggered by passing NULL
search parameters to the LDAP service.  An unauthenticated attacker
may be able to leverage either issue to execute code on the remote
host with SYSTEM privileges.");
