Microsoft : Security Vulnerabilities, CVEs, Published In April 2003

The RPC component in Windows 2000, Windows NT 4.0, and Windows XP allows remote attackers to cause a denial of service (disabled RPC service) via a malformed packet to the RPC Endpoint Mapper at TCP port 135, which triggers a null pointer dereference.

Microsoft Word and Excel allow remote attackers to steal sensitive information via certain field codes that insert the information when the document is returned to the attacker, as demonstrated in Word using (1) INCLUDETEXT or (2) INCLUDEPICTURE, aka "Flaw in Word Fields and Excel External Updates Could Lead to Information Disclosure."
