Buffer overflow in Lotus Domino web server before R5.0.10, when logging to DOMLOG.NSF, allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a long HTTP Authenticate header containing certain non-ASCII characters.
Lotus Domino 5.0.8 web server returns different error messages when a valid or invalid user is provided in HTTP requests, which allows remote attackers to determine valid user names and makes it easier to conduct brute force attacks.

Lotus Domino server 5.0.9a and earlier allows remote attackers to bypass security restrictions and view Notes database files and possibly sensitive Notes template files (.ntf) via an HTTP request with a large number of "+" characters before the .nsf file extension, which are converted to spaces by Domino.
The default configuration of Lotus Domino server 5.0.8 includes system information (version, operating system, and build date) in the HTTP headers of replies, which allows remote attackers to obtain sensitive information.
