Another Internet Explorer flaw

It has been a rough year for Microsoft. And for the users who haven’t yet switched to XP, or upgraded using SP2. Almost every month brought a new vulnerability in some version of IE. There were notably fewer in XP+SP2 than in other combinations. For those still using some flavour of 9X, NT or 2000, the wait for a patch has been a long, painful one.

The patch for the infamous IFRAME buffer overflow was posted on December 1st, 2004, almost one month after it was reported, in the form of the MS04-040 security update.

Today, exactly one week after MS04-040, Secunia Research has announced yet another vulnerability in IE, affecting IE 5, 5.5 and 6, on various operating systems, XP+SP2 included. In their own words: “Secunia Research has reported a vulnerability in Microsoft Internet Explorer, which can be exploited by malicious people to spoof the content of websites.”

Luckily, this vulnerability is not a critical one. But it will be no doubt a nice addition to scammers bag of tricks, trying to lure you into filling out online forms on fake sites which claim to be eBay.com or your e-banking interface.

Because it’s not a critical vulnerability, it means we probably won’t be seeing an epidemic based on this flaw, but beware of scam and phishing e-mails relying on this trick. Moreover, because this is not just an IE vulnerability, many other browsers are affected as well, increasing the potential for abuse.
