Opera < 10.00 Multiple Vulnerabilities

Medium Nessus Network Monitor Plugin ID 5146


The remote host is vulnerable to multiple attack vectors.


The version of Opera installed on the remote host is earlier than 10.00 and thus potentially affected by multiple issues :

- The collapsed Address bar can in some cases temporarily show the previous domain of the present site.

- Certificates which use a wild card immediately before the top level domain, or nulls in the domain name, may pass validation checks in Opera.

- Some Unicode characters are treated incorrectly which might cause international domain names that use them to be shown in the wrong format. Showing these addresses in Unicode instead of punycode could allow for limited address spoofing.

- Opera does not check the revocation status for intermediate certificates not served by the server.


Upgrade to Opera 10.00 or later.
