Microsoft Windows 2000 Local Troubleshooter ActiveX control buffer overflow
| win2k-local-troubleshooter-bo (13423) |  High Risk |
Description:
Microsoft Windows 2000 is vulnerable to a buffer overflow in the Microsoft Local Troubleshooter ActiveX control (Tshoot.ocx), caused by improper validation of parameters. The Tshoot.ocx ActiveX control assists in diagnosing problems and is used by the Microsoft Windows Troubleshooting and Help System, which is installed by default on Microsoft Windows 2000. By creating a specially-crafted Web page, a remote attacker could overflow a buffer and execute arbitrary code on the victim's computer with privileges of the victim, once the page is viewed. An attacker could exploit this vulnerability by hosting the malicious Web page on a Web site or by sending it to a victim as an HTML email.
