EDraw Office Viewer ActiveX (officeviewer.ocx) HttpDownloadFileToTempDir Method Overflow

High Nessus Plugin ID 26198


The remote Windows host has an ActiveX control that is affected by a buffer overflow vulnerability.


The remote host contains the EDraw Office Viewer Component, an ActiveX control for working with Microsoft Office documents.

The version of this control installed on the remote host contains a buffer overflow that can be triggered by a long value for the first argument of the 'HttpDownloadFileToTempDir' method. If an attacker can trick a user on the affected host into visiting a specially crafted web page, this method could be leveraged to execute arbitrary code on the affected system subject to the user's privileges.


Upgrade to EDraw Office Viewer Component 5.3 or later.
