The version of Opera installed on the remote host is vulnerable to various security flaws, ranging from cross-site scripting to buffer overflows. 

To exploit them, an attacker would need to set up a rogue website, then lure a user of this host visit it using Opera.  He would then be able to execute arbitrary code on this host.

The version of Opera installed on the remote host is earlier than 8.01 and thus reportedly affected by multiple issues :

  - It may be possible for a malicious website to spoof     dialog boxes.

  - It may be possible for a XMLHttpRequest object to gain     unauthorized access to sensitive data.

  - The installed version is affected by multiple cross-site     scripting vulnerabilities.

  - When using the GET form, file path information could be     disclosed.

The remote host is using a version of Opera that is prone to a security flaw where a malicious attacker can inject malicious data into a URI.  Such an attack would require that the attacker be able to convince an Opera user to browse to a malicious URI.  Successful exploitation would result in the attacker gaining access to confidential data (such as authentication cookies) or executing code within the browser.
