Disclosure Date


Opera contains a flaw that is triggered when the download dialog box is allowed to be displayed within an excessively small window. This may allow a context-dependent attacker to effectively make the download box not appear to the user, which may allow them to more easily trick the user into downloading an arbitrary file by convincing them to enter a series of keystrokes that will approve the download.
