DESCRIPTION: shinnai has reported some vulnerabilities in Microsoft Visual Studio, which can be exploited by malicious people to overwrite arbitrary files or potentially compromise a vulnerable system.



1) The "StartProcess()" and "SyncShell()" methods of the PDWizard.ocx ActiveX control can be exploited to execute arbitrary commands on the system. Other insecure methods have also been reported e.g. "SaveAs()", "CABDefaultURL()", "CABFileName()", and "CABRunFile()".

2) The "Load()" and "SaveAs()" methods of the VBTOVSI.DLL ActiveX control can be exploited to e.g. load a local file and save it in an arbitrary location or overwrite an arbitrary file.

The vulnerabilities are reported in version 6.0. Other versions may also be affected.

SOLUTION: Set the kill-bit for the ActiveX controls.
