Description:
Microsoft has issued patches to fix a vulnerability in the Windows Trouble Shooter ActiveX Control. This can be exploited by malicious HTML documents like web sites and emails to compromise a user's system.
The vulnerability is caused due to a boundary error in the Windows Trouble Shooter ActiveX Control's "RunQuery2" method. This can be exploited to cause a buffer overflow by supplying an overly long string to the first parameter. The ActiveX control is marked "safe for scripting" allowing any web site to reference it.
Successful exploitation allows execution of arbitrary code on a user's system.
The Windows Trouble Shooter ActiveX Control is installed by default on Windows 2000 systems.
