I just ran COMbust on the DLL and could not find anything obvious. A couple of crashes, but no BOs. If you want to explore it more, give COMbust a try: http://atstake.com/research/tools/vulnerability_scanning/ -Fred Frederic Bret-Mounet, CISSP T 415.352.5116 M 415.305.2899 fbret () atstake com www.atstake.com -----Original Message----- From: full-disclosure-admin () lists netsys com [mailto:full-disclosure-admin () lists netsys com] On Behalf Of Richard M. Smith Sent: Wednesday, October 08, 2003 7:26 PM To: full-disclosure () lists netsys com Subject: [Full-disclosure] The msvidctl.dll in Windows XP Hi, On my Windows XP laptop, I found a large number of ActiveX controls in the system file msvidctl.dll which are marked safe for scripting. I've attached a list of the controls in this DLL. I'm really curious why this DLL is installed on my system in the first place since the laptop doesn't have a TV tuner and why these controls need to be marked safe for scripting. Also does anyone know if this DLL is installed by default in all/most Windows XP systems? My concern with this DLL, is that some number of security holes have slipped by Microsoft given the large quantity of ActiveX methods and properties that need to checked out here. Thanks, Richard M.
