The remote host is using Opera - an alternative web browser.

This version of Opera is vulnerable to a security weakness 
that may permit malicious web pages to spoof address bar information.

This is reportedly possible through malicious use of the 
JavaScript 'unOnload' event handler when the browser 
is redirected to another page.

This issue could be exploited to spoof the domain of a malicious web page, 
potentially causing the victim user to trust the spoofed domain.

Solution : Install Opera 7.50 or newer.
Risk factor : High";
