With McAfee's Security Risk Management approach, customers can effectively address business priorities and security realities. McAfee's award-winning solutions identify and block known and unknown attacks before they can cause damage. McAfee will continue to update its coverage as needed as new exploit vectors are discovered and as new threats emerge.

Out of the box, Host IPS protects against many buffer overflow exploits. McAfee Host IPS v6.0 and McAfee Entercept® protect users against code execution that may result from common classes of exploits targeted at the buffer overflow/overrun vulnerabilities in Microsoft Excel, Word, Office, Explorer, CAPICOM, and DNS RPC. This "out of the box" protection is provided without the need for security content updates for either product.

The McAfee Vulnerability Shield package for McAfee Host IPS v6.0 customers provides specific protection against common classes of exploits targeted at the vulnerabilities in Microsoft Exchange, Internet Explorer, and CAPICOM. Coverage was provided in a previous Vulnerability Shield package for the vulnerability in Windows DNS RPC. The Vulnerability Shield package is deployed through McAfee ePolicy Orchestrator® to agents, protecting systems without a reboot.

McAfee VirusScan® Enterprise 8.0i and McAfee Managed VirusScan with AntiSpyware protects users against code execution that may result from common classes of exploits targeted at the buffer overflow/overrun vulnerabilities in Microsoft Excel, Word, Office, Internet Explorer, and CAPICOM.

McAfee IntruShield® provides coverage for Microsoft Excel, Word, Office, Exchange, Internet Explorer, and CAPICOM vulnerabilities through signature sets released today. Coverage was provided in previous signature sets for the vulnerability in Windows DNS RPC. McAfee IntruShield sensors deployed in in- line mode can be configured with a response action to drop such packets for preventing these attacks.

The McAfee System Compliance Profiler, a component of McAfee ePolicy Orchestrator, is being updated for today's newly disclosed vulnerabilities in Microsoft Excel, Word, Office, Exchange, Internet Explorer, CAPICOM, and Windows DNS RPC to quickly assess compliance levels of the security patches announced today.

The McAfee Foundstone® and McAfee Policy Enforcer checks are being created to detect the vulnerabilities announced today, and will be available in the packages released today and the day after tomorrow, respectively. These checks are expected to accurately identify if a system is vulnerable in many enterprise environments.

McAfee Policy Auditor compliance checks and McAfee Remediation Manager remediations are being created to identify unpatched systems and apply the necessary patches to affected systems for the vulnerabilities in Microsoft Excel, Word, Office, Exchange, Internet Explorer, CAPICOM, and Windows DNS RPC. Updates will be available in the next V-Flash package.

Avert DAT files have already been released to detect known exploits and new detection will be added as new exploits are discovered. DAT files are used by McAfee GroupShield®, PortalShield(TM), Secure Internet Gateway appliances, Secure Messaging Gateway appliances, Secure Web Gateway appliances, Total Protection suites, VirusScan Enterprise, VirusScan Command Line, VirusScan Online and other McAfee scanners. McAfee users can refer to for information regarding any new threats attempting to exploit these vulnerabilities.
