Lotus Domino server 5.0.9a and earlier allows remote attackers to cause a denial of service by exhausting the number of working threads via a large number of HTTP requests for (1) an MS-DOS device name and (2) an MS-DOS device name with a large number of characters appended to the device name.

Lotus Domino Servers 5.x, 4.6x, and 4.5x allows attackers to bypass the intended Reader and Author access list for a document's object via a Notes API call (NSFDbReadObject) that directly accesses the object.

Buffer overflow in Lotus Notes LDAP (NLDAP) allows an attacker to conduct a denial of service through the ldap_search request.
