    Executive Summary:
    ------------------
    This update resolves a newly-discovered vulnerability. A remote code
    execution vulnerability exists in the Help and Support Center because of
    the way that it handles HCP URL validation. The vulnerability is
    documented in the Vulnerability Details section of this bulletin.

    If a user is logged on with administrative privileges, an attacker who
    successfully exploited this vulnerability could take complete control of
    an affected system, including installing programs; viewing, changing, or
    deleting data; or creating new accounts with full privileges. Users
    whose accounts are configured to have fewer privileges on the system
    would be at less risk than users who operate with administrative
    privileges.

    Technical Description:
    ----------------------
    * Help and Support Center Vulnerability - CAN-2004-0199: A remote code
    execution vulnerability exists in the Help and Support Center because of
    the way that it handles HCP URL validation. An attacker could exploit
    the vulnerability by constructing a malicious HCP URL that could
    potentially allow remote code execution if a user visited a malicious
    Web site or viewed a malicious e-mail message. An attacker who
    successfully exploited this vulnerability could take complete control of
    an affected system. However, significant user interaction is required to
    exploit this vulnerability.
