Microsoft's ubiquitous IE web browser software became the subject of yet another security flap this week.

The latest buffer overflow vulnerability could be used to inject hostile code into vulnerable systems, security clearing house US CERT warned yesterday.

The flaw stems from a bug in the way particular versions of IE process certain attributes in the IFRAME HTML tag. IE6 on Win XP SP1 and Win 2000 are both vulnerable.

But Win XP SP2 is safe from what Secunia describes as an "extremely critical" bug. It warns that a working exploit has been published.

Secunia advises users to either use Win XP SP2 or to try an alternative browser. US CERT reckons disabling active scripting might be enough. ®
