Attached files are opened without any warnings directly from the user's cache directory. This can be exploited to execute arbitrary JavaScript in context of "file://". 2. Normally, filename extensions are determined by the "Content-Type" in Opera Mail. However, by appending an additional '.' to the end of a filename, an HTML file could be spoofed to be e.g. "image.jpg.". The two vulnerabilities combined may be exploited to conduct script insertion attacks if the user chooses to view an attachment named e.g. "image.jpg." e.g. resulting in disclosure of local files. The vulnerabilities have been confirmed in Opera version 8.02, prior versions may also be vulnerable. SOLUTION: Update to version 8.50. http://www.opera.com/download/ PROVIDED AND/OR DISCOVERED BY: Jakob Balle, Secunia Research.
