The remote host contains a web browser that is affected by a truncated dialog vulnerability.
The version of Opera installed on the remote host is earlier than 12.02 and is, therefore, reportedly affected by a truncated dialog vulnerability. Certain user actions, when combined with specially crafted web pages, can cause displayed dialog boxes to be too small thus allowing the dialog buttons to be hidden. A user may be tricked into clicking what appear to be elements on the underlying page, but are actually the hidden dialog buttons. This can allow arbitrary code execution to occur.
