Advisory Content (Page 1 of 3)[ 1 ] [ 2 ] [ 3 ]

Description:
A vulnerability has been identified in a Microsoft ActiveX plugin called MCIWNDX.OCX, which possibly allows malicious HTML documents to execute arbitrary code on a vulnerable system.

The problem is that a property called "Filename" isn't properly verified allowing malicious websites or HTML emails to cause a buffer overflow by supplying an overly long string. This could potentially be exploited to execute arbitrary code on the system.

This plugin is part of Visual Studio version 6. However, since the plugin is digitally signed by Microsoft, it may be silently installed through Internet Explorer by any website.
