Microsoft says Internet Explorer versions 6 through 10 are subjects of two critical Patch Tuesday updates for February that could address recent Java woes.
Both critical patches address vulnerabilities that could give attackers access to client browsers and from there access to the underlying host, says Alex Horan a senior product manager at CORE Security. "Bulletins 1 and 2 target all versions of Internet Explorer on essentially all versions of Windows platforms, so it's pretty much one-hack fits all in the Windows environment for attackers," he says. "I expect a lot of interest in developing a working exploit for this vulnerability."
