Description:
A weakness has been discovered in Firefox, which potentially can be exploited by malicious people to disclose sensitive information.
The weakness is caused due to a design error within the focus handling of form fields and can potentially be exploited by changing the focus from a "textarea" field to a "file upload" form field via the "OnKeyDown" event.
Successful exploitation allows an arbitrary file on the user's system to be uploaded to a malicious web site, but requires that the user is tricked into typing the file name into a "textarea" input form.
The weakness is confirmed in version 2.0.0.4. Other versions may also be affected.
Do you have this product installed on your home computer? Scan using the free Personal Software Inspector. Check if a vulnerable version is installed on computers in your corporate network, using the Network Software Inspector.
Solution:
Update to version 2.0.0.8.
