Cumulative Security Update for Internet Explorer (2879017)

Published: Tuesday, October 08, 2013

Version: 1.2

General Information

Executive Summary

This security update resolves one publicly disclosed vulnerability and nine 
privately reported vulnerabilities in Internet Explorer. The most severe 
vulnerabilities could allow remote code execution if a user views a specially 
crafted webpage using Internet Explorer. An attacker who successfully 
exploited the most severe of these vulnerabilities could gain the same user 
rights as the current user. Users whose accounts are configured to have fewer 
user rights on the system could be less impacted than users who operate with 
administrative user rights.

This security update is rated Critical for Internet Explorer 6, Internet 
Explorer 7, Internet Explorer 8, Internet Explorer 9, Internet Explorer 10, 
and Internet Explorer 11 on Windows clients and Moderate for Internet Explorer 
6, Internet Explorer 7, Internet Explorer 8, Internet Explorer 9, Internet 
Explorer 10, and Internet Explorer 11 on Windows servers.
