Microsoft releases security update
This security update resolves two privately reported vulnerabilities and one publicly disclosed vulnerability in Microsoft Server Message Block (SMB) Protocol. The vulnerabilities could allow remote code execution on affected systems.
An attacker who successfully exploited these vulnerabilities could install programs; view, change, or delete data; or create new accounts with full user rights. Firewall best practices and standard default firewall configurations can help protect networks from attacks that originate outside the enterprise perimeter. Best practices recommend that systems that are connected to the Internet have a minimal number of ports exposed.
This security update is rated Critical for all supported editions of Microsoft Windows 2000, Windows XP, and Windows Server 2003, and Moderate for all supported editions of Windows Vista, and Windows Server 2008.
Security updates can be downloaded from the Microsoft Update Catalog which provides a searchable catalog of content made available through Windows Update and Microsoft Update, including security updates, drivers and service packs.
