This update also includes a kill bit for the Yahoo! Music Jukebox product. The vulnerability could allow remote code execution if a user viewed 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 is rated Critical for Internet Explorer 5.01 Service Pack 4 on Microsoft Windows 2000 Service Pack 4; Internet Explorer 6 Service Pack 1 when installed on Microsoft Windows 2000 Service Pack 4; Windows XP Service Pack 2; and Windows XP Professional x64 Edition and Windows XP Professional x64 Edition Service Pack 2. The security update is rated Important for Windows Vista and Windows Vista Service Pack 1; and Windows Vista x64 Edition and Windows Vista x64 Edition Service Pack 1. The security update is rated Moderate for all supported editions of Windows Server 2003. For all other supported versions of Windows, this security update is rated Low. For more information, see the subsection, Affected and Non-Affected Software, in this section. The security update addresses the vulnerability by setting a kill bit so the vulnerable controls do not run in Internet Explorer. For more information about the vulnerability, see the Frequently Asked Questions (FAQ) subsection under the next section, Vulnerability Information. Recommendation. Microsoft recommends that customers apply the update immediately. Known Issues. No known issues.
