This security update resolves vulnerabilities in Internet Explorer. The most severe of the vulnerabilities could allow remote code execution if a user views a specially crafted webpage using Internet Explorer. An attacker who successfully exploited these vulnerabilities could gain the same user rights as the current user. Customers whose accounts are configured to have fewer user rights on the system could be less impacted than those who operate with administrative user rights.
Revision Note: V2.0 (April 30, 2015): Updated bulletin to inform customers running Internet Explorer on Windows Server 2003 Service Pack 2 that the 3038314 update on the Microsoft Download Center was updated on April 22, 2015. Microsoft recommends that customers who installed the 3038314 update prior to April 22 should reinstall the update to be fully protected from the vulnerabilities discussed in this bulletin.
