TITLE:
Opera Download Dialog Spoofing Vulnerability

SECUNIA ADVISORY ID:
SA15870

VERIFY ADVISORY:
http://secunia.com/advisories/15870/

CRITICAL:
Moderately critical

IMPACT:
Spoofing

WHERE:
From remote

SOFTWARE:
Opera 8.x
http://secunia.com/product/4932/

DESCRIPTION:
Secunia Research has discovered a vulnerability in Opera, which can
be exploited by malicious people to trick users into executing
malicious files.

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.
