Vulnerability Advisory: McAfee, Inc. Solutions Protect Against Four Newly Disclosed Microsoft Vulnerabilities

McAfee Intrusion Prevention and Security Risk Management Solutions Provide Protection to Identify and Block Potential New Attacks

SANTA CLARA, Calif., Sept. 11 -- McAfee, Inc. (NYSE:MFE), announced that it provides coverage for the four security vulnerabilities disclosed by Microsoft Corporation today. These vulnerabilities have been reviewed by McAfee® Avert® Labs, and based on their findings, McAfee recommends that users confirm the Microsoft product versioning outlined in the bulletins and update as recommended by Microsoft and McAfee. This includes deploying solutions to ensure protection against the vulnerabilities outlined in this advisory.

"Compared to last month, Patch Tuesday in September is almost anticlimactic," said Dave Marcus, security research and communications manager at McAfee Avert Labs. "Users of Windows Server 2000 Service Pack 4 should be paying most attention to Microsoft's patches. The MSN Messenger and Windows Live Messenger vulnerability is also serious, but since Microsoft pushes the updates there is little chance of successful attacks exploiting this vulnerability."

Microsoft Vulnerabilities Overview:
o MS07-051 - Vulnerability in Microsoft Agent could allow remote code execution
o MS07-052 - Vulnerability in Crystal Reports for Visual Studio could allow remote code execution
o MS07-053 - Vulnerability in Windows Services for Unix could allow elevation of privilege
o MS07-054 - Vulnerability in MSN Messenger and Windows Live Messenger could allow remote code execution

Scope of Potential Compromise

Today's four security bulletins cover a total of four vulnerabilities. One of the bulletins is rated critical by Microsoft due to the potential for remote code execution. The three remaining bulletins are deemed important.

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 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 Agent. 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 customers provides specific protection against common classes of exploits targeted at the vulnerabilities in Microsoft Agent and Windows Services for Unix. The Vulnerability Shield package is deployed through McAfee ePolicy Orchestrator® to agents, protecting systems without a reboot.

McAfee IntruShield® provides coverage for Microsoft Agent and Crystal Reports for Visual Studio vulnerabilities through signature sets released today. Additionally, IntruShield has protected against the MSN Messenger and Windows Live Messenger vulnerability since February. 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 Agent, Crystal Reports for Visual Studio, Windows Services for Unix and MSN Messenger and Windows Live Messenger to quickly assess compliance levels of the security patches announced today.

The McAfee Foundstone® and McAfee Network Access Control 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 Agent, Crystal Reports for Visual Studio, Windows Services for Unix and MSN Messenger and Windows Live Messenger. 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.
