Microsoft is to address the vulnerability in Internet Explorer 8 that could potentially lead to zero-day attacks in its May Patch Tuesday next week.
The vulnerability has already been exploited during a watering hole attack targeting the US Department of Labor (DoL) website and security researchers are advising users of IE8 that this patch, rated ‘critical', should be implemented first.
In its Advance Notification, Microsoft announced that there will be a further nine bulletins addressing 33 unique vulnerabilities. Of these, one more is rated critical and affects Microsoft Windows and eight are ‘important' and concern problems in Windows, Office, Server, Tools and .Net Framework, Dustin Childs, group manager at Microsoft Trustworthy Computing, confirmed.
Wolfgang Kandek, chief technical officer at Qualys, said in a blog post that five of these bulletins allow for remote code execution and these “should be the focus points for your patching next week”.
Kandek also revealed that Adobe will release a patch covering the zero-day vulnerability affecting ColdFusion and a new version of Adobe Reader on the same day.
