Information Week article notes:
The "highly criticial" vulnerability affects Internet Explorer 5.01, 5.5, and 6 on fully patched PCs running either Windows XP SP1 or the newer SP2.
Another flaw in Internet Explorer has been uncovered by Danish security firm Secunia, which said that the gaffe left all PC users open to attack, even those who had updated Windows XP with the massive Service Pack 2 upgrade.
