Critical

Severity Rating: Critical - Revision Note: V1.1 (September 9, 2009): Corrected the update package file name for JScript 5.6 on all supported x64-based editions of Windows Server 2003.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.
