Microsoft Pushes Emergency Patch for IE

Summary: Microsoft released an emergency update in August 2015 to fix a critical flaw in all supported versions of Internet Explorer, from IE7 to IE11, that lets an attacker own a system when a user merely browses to a malicious or hacked website. Qualys CTO Wolfgang Kandek said the vulnerability, CVE-2015-2502, is actively being exploited in the wild, with attack code hosted on a malicious webpage, and the advisory credits a Google employee with reporting it.

Key Takeaway: The patch applies to every Windows user whether or not they browse with IE, because IE components are invoked by applications such as Microsoft Office, so a single unpatched machine is exposed through software its owner may not connect to the browser at all.
