The Problem
Users of Opera 8.1 may be at
risk of attack. Security firm
Secunia has uncovered a
security weakness in that
version. Researchers at Secunia
said they found that a design
error in the way Opera
processes mouse clicks in new
browser windows. This,
combined with the
predictability of the position of
the ‘File Download’ dialog box,
could be exploited to trick
users into clicking the ‘Open’
button of a file download
prompt, even if they intended
to click ‘Save’ or ‘Cancel’.
The exploit has only been
verified to work in Opera
version 8.01, though earlier
versions may be vulnerable too.
The Damages
Naturally, you wouldn’t want to
click ‘Open’ for a file you intend
to save and then virus-check.
And if you’re prompted to save
or open a file from an untrusted
source, you’re more likely to
click ‘Cancel’!
Hackers could use the weakness
to trick users into downloading
and running unwanted
programs. The flaw cannot be
taken lightly—running a malicious
program could damage
your computer!
The Solution
The flaw was eliminated in
Opera version 8.02, but why
not upgrade to the latest
version—8.51? The update is
available at www.opera.com/
download.
