Description

While on an insecure page triggering a load of a binary file from a secure server will cause the SSL lock icon to appear. The certificate information is that of the binary file's host, while the location bar URL correctly shows the original insecure page.

This could potentially be abused by phishers to make their fake login sites appear more authentic.

Workaround

Upgrade to fixed version
