Microsoft Security Bulletin MS14-010 – Critical
This security update resolves twenty-three privately reported and one publicly disclosed vulnerabilities in Internet Explorer. The most severe vulnerabilities could allow remote code execution if a user views a specially crafted Web page 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, Moderate for Internet Explorer 6, Internet Explorer 7 on Windows servers, and Important for Internet Explorer 8, Internet Explorer 9, Internet Explorer 10, and Internet Explorer 11 on Windows servers. For more information, see the full bulletin.
