Opera < 12.02 Truncated Dialog Vulnerability

High Nessus Plugin ID 61732

Synopsis

The remote host contains a web browser that is affected by a truncated dialog vulnerability.

Description

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.

Solution

Upgrade to Opera 12.02 or later.
