Opera web browser URI obfuscation

Vulnerability Assessment Summary
Check version of Opera for URI obfuscation bug

Detailed Explanation for this Vulnerability Assessment

The version of Opera installed on the remote host is vulnerable to a
flaw wherein a remote attacker can obscure the URI, leading the user
to believe that he/she is accessing a trusted resource.

To exploit this issue, a possible hacker would need to set up a rogue web
site, then entice a local user to visit the site. Successful
exploitation would enable the attacker to execute arbitrary code on
this host.
