The Microsoft Windows Simple Mail Transfer Protocol (SMTP) Server is
prone to a denial-of-service vulnerability and to to an information-disclosure vulnerability.
Successful exploits of the denial-of-service vulnerability will cause the
affected SMTP server to stop responding, denying service to legitimate users.
Attackers can exploit the information-disclosure issue to gain access to
sensitive information. Any information obtained may lead to further attacks.
