Original Bulletin:    
http://www.hitachi-support.com/security_e/vuls_e/HS06-018_e/index-e.html


OVERVIEW:
        
        Multiple vulnerabilities have been announced in the Hitachi 
        Directory Server which may result in the execution of arbitrary code 
        and/or a denial of service.


IMPACT: 

        Sending specially crafted LDAP requests results in memory leaks 
        and buffer overflows. These vulnerabilities may be exploited to 
        execute arbitrary code or cause a denial of service of the Directory 
        Server.


MITIGATION:

        A non-vulnerable release of Hitachi Directory Server has been 
        released correcting these issues. Administrators are encouraged to 
        upgrade to versions 02-11-/K or 02-10-/V. More information can be 
        found on the Hitachi web site [1].
