Description:
Secunia Research has discovered two vulnerabilities in the Opera Mail client, which can be exploited by a malicious person to conduct script insertion attacks and to spoof the name of attached files.
1. 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.
NOTE: Some other security issues with unknown impacts have also been reported by the vendor.
Solution:
Update to version 8.50.
