Description

Opera has been found vulnerable to a buffer overflow in the handling of filenames when showing the "Download Dialog" box.

The problem is that very long filenames are handled incorrectly. This allows a malicious website to create a filename that causes a buffer overflow which can be exploited to execute arbitrary code.

Exploits are in the wild for Windows.

Exploitation does not require user interaction as websites can spawn the "Download Dialog" automatically.


Solution
Upgrade to version 7.0.3.
