DESCRIPTION:

The vulnerability is caused due to an error within the

"Search()" method, which takes in a VARIANT as the "varBrowser"
argument. This can be exploited to execute arbitrary code when a user
e.g. visits a malicious website.
The vulnerability is confirmed in version 3.0.2.1098. Other versions
may also be affected.
