Description: This security update resolves seven privately reported vulnerabilities and one publicly disclosed vulnerability in Internet Explorer. The more severe of the vulnerabilities could allow remote code execution if a user views a specially crafted Web page using Internet Explorer. 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. The security update addresses these vulnerabilities by modifying the way that Internet Explorer handles scripts and cached content and initializes memory.
