fix

ngs

>"As if to prove the point that security is like the Dutch

>(DAC)...Wednesday, Secunia issued a warning saying it had
>discovered a vulnerability within IE that allowed
scammers
>to spoof, or fake, the content of a site displayed in the
>browser.
>- On Friday, however, the security vendor modified the
>alert to claim that virtually every browser, from
Internet
>Explorer and Mozilla to Opera and Netscape -- including
>browsers for both Windows and the Mac OS -- has this
>flaw. "It's not a code vulnerability," said Secunia's
>Kristensen, "but a design flaw." The problem stems from
>how browsers handle frames. "Some time ago, browser
>designers decided that one site needed to be able to
>manipulate the content of another, and the functionality
>was adopted by everyone," said Kristensen. But hackers
can
>use this to inject phony content -- say their own credit
>card-stealing form -- into a frame of an actual trusted
>Web site, such as a user's online bank. "In these times
of
>phishing attacks and other scams, this is a problem,"
said
>Kristensen. "You're visiting a bank or an e-commerce
site,
>and you're certain of that site, but meanwhile, it's
>[actually] open in the background to content change by
>hackers." Internet Explorer users can stymie such
spoofing
>attacks by disabling the "Navigate sub-frames across
>different domains" setting under Tools/Internet
>Options/Security.
>Secunia offered up a quick test that users can run to see
>if their current browser is vulnerable to this problem."
