A function built into all major browsers could be co-opted by attackers to fool Web site visitors into surrendering sensitive information, a security firm warned on Wednesday.
The issue, which security firm Secunia labeled a flaw, could allow a malicious Web site to refer visitors to a legitimate site--such as a bank's Web site--and then control the content displayed in a pop-up windows. The issue affects Microsoft's Internet Explorer, the Mozilla Foundation's Mozilla and Firefox browsers, Opera's browser, the open-source Konqueror browser and Apple Computer's Safari, the firm stated in advisories on its site.
