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.");
