There’s a zero-day security flaw in Internet Explorer that’s been known for at least the last 7 months, yet Microsoft has yet to release a patch. Perhaps it never will – after all, IE8 is the last version of Microsoft’s browser to support Windows XP, which itself is now an unsupported operating system. Alternately, Microsoft might just be having a really tough time with this one – the Redmond outfit doesn’t have a whole lot to say on the matter. According to Zero Day Initiative, the vulnerability allows remote hackers to execute arbitrary code on vulnerable installations.
