The vulnerability is caused due to an error in the handling of extended ASCII codes in the download dialog. This can be exploited to spoof the file extension in the file download dialog via a specially crafted "Content-Disposition" HTTP header. Successful exploitation may result in users being tricked into executing a malicious file via the download dialog, but requires that the "Arial Unicode MS" font (ARIALUNI.TTF) has been installed on the system. NOTE: The "Arial Unicode MS" font is installed with various Microsoft Office distributions. The vulnerability has been confirmed in version 8.01. Other versions may also be affected. SOLUTION: Update to version 8.02. http://www.opera.com/download/ PROVIDED AND/OR DISCOVERED BY: Andreas Sandblad, Secunia Research. ---------------------------------------------------------------------- About: This Advisory was delivered by Secunia as a free service to help everybody keeping their systems up to date against the latest vulnerabilities.
