The NDSD process in Novell eDirectory 8.7.3 before 184.108.40.206 ftf2 and eDirectory 8.8 before 8.8.5 ftf1 does not properly handle certain LDAP search requests, which allows remote attackers to cause a denial of service (application hang) via a search request with a NULL BaseDN value. Per: http://www.novell.com/support/viewContent.do?externalId=7004721
This vulnerability is resolved in eDirectory 8.8.5 ftf1 and eDirectory 220.127.116.11 ftf2.
To resolve this problem, apply eDirectory 8.8.5 ftf1 or newer for eDirectory 8.8.X and eDirectory 18.104.22.168 ftf2 for eDirectory 8.7.3.X. Patches are available at http://download.novell.com"
