CriticalSeverity Rating: Critical - Revision Note: V2.0 (November 10, 2009): Added JScript 5.7 on Microsoft Windows 2000 Service Pack 4 (KB975542) to the Affected Software table and the Security Update Deployment section.Summary: This security update resolves a privately reported vulnerability in the JScript scripting engine that could allow remote code execution if a user opened a specially crafted file or visited a specially crafted Web site and invoked a malformed script. If a user is logged on with administrative user rights, an attacker who successfully exploited this vulnerability could take complete control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. 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.
