Buffer overflow in the HTML Help ActiveX Control (hhctrl.ocx) in Microsoft Windows 98, 98 Second Edition, Millennium Edition, NT 4.0, NT 4.0 Terminal Server Edition, Windows 2000, and Windows XP allows remote attackers to execute code via (1) a long parameter to the Alink function, or (2) script containing a long argument to the showHelp function.

Security readout for executives and security teams

This is a legacy Microsoft Windows flaw in the HTML Help ActiveX control. A malicious web page or script could crash the control and potentially run attacker-controlled code. The business risk is mainly for any still-running Windows 98, ME, NT 4.0, 2000, or XP systems. Exposure is likely limited to legacy Windows systems listed in the CVE: Windows 98, 98 SE, ME, NT 4.0, NT 4.0 Terminal Server, Windows 2000, and Windows XP. Confirm whether HTML Help ActiveX control is present and reachable through browser or email workflows. Treat this as urgent only if the organization still operates the named legacy Windows systems. For modern environments, priority is asset verification. For exposed legacy systems, prioritize retirement, patch confirmation, and isolation. Mitigation focus: Identify and retire affected legacy Windows systems where possible.; Review and apply Microsoft MS02-055 guidance for systems that cannot be retired.; Restrict legacy web and email client use on affected hosts..
