“Microsoft released two eagerly awaited updates for Internet Explorer today, both addressing serious security issues.
Security update MS12-063 addresses the IE vulnerability described in Security Advisory 2757760, which has already resulted in some targeted zero-day attacks but has not been widely exploited. A “Fix It” tool was released earlier this week to mitigate the problem. This update patches the underlying vulnerability in Internet Explorer versions 6, 7, 8, and 9. The issue doesn’t affect IE 10 in Windows 8.
The company also released Security Advisory 2755801, which addresses all publicly known issues affecting Adobe Flash Player in Internet Explorer 10 on Windows 8. This release is exactly one month later than Adobe’s release of the same update for other platforms, including Internet Explorer 9 and earlier.
Both updates will be delivered through Automatic Updates or can be manually installed”.
