• Malformed Hit-Highlighting Argument Security Vulnerability
  This update resolves a vulnerability that could allow a malicious Web surfer to gain unauthorized access to view files if running Web services and file indexing services. For more information on this vulnerability, please visit Microsoft Security Bulletin MS00-006.

The flaw involves how the service handles a particular type of SMTP command used to transfer the data that constitutes an incoming mail. By sending a malformed version of this command, an attacker could cause the SMTP service to fail. This would have the effect of disrupting mail services on the affected system, but would not cause the operating system itself to fail.
