Microsoft has released a fix for Internet Explorer that addresses twenty-nine different vulnerabilities. One of them is a previously unknown vulnerability offered up to Hacking Team that researchers discovered in the company’s leaked emails. The vulnerability is an exploitable use-after-free (UAF) vulnerability that occurs within a custom heap in JSCRIPT9. It could allow an attacker to bypass protections found in standard memory. The fix affects fully patched versions of Internet Explorer 11 on both Windows 7 and Windows 8.1.”]
