Some vulnerabilities have been reported in Lotus Domino, which can be exploited by malicious people to conduct cross-site scripting attacks and to cause a DoS (Denial of Service).

1) Input passed to the "BaseTarget" and "Src" parameters isn't properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.

The vulnerabilities have been reported in version 6.5, 6.5.4, and 6.5.4.1. Prior versions may also be affected.

2) Memory leaks in the HTTP process and in the Domino server when handling SSL handshake may cause the exhaustion of virtual memory, potentially causing the service to crash.

3) A memory leak in the HTTP process when handling X.509 certificate verification may cause the exhaustion of virtual memory, potentially causing the service to crash.

4) A NULL pointer dereferencing error when handling the authentication phase of a connection after recovery from transient low memory conditions can cause the service to crash.

Some other issues, which may be security related has also been fixed.

Solution
Update to Domino 6.5.4 Fix Pack 1 (6.5.4.1).
