McAfee Solutions

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 Entercept, by default, protects users against code execution that may result from exploitation of the buffer overflow/overrun vulnerabilities reported in MS05-046, MS05-047, MS05-048, MS05-050, MS05-051 and MS05-052. This protection functions regardless of whether the latest McAfee Entercept security content has been updated. Additionally, both McAfee VirusScan Enterprise 8.0i and McAfee Managed VirusScan protect against attacks targeting the buffer overflow vulnerabilities reported in MS05-046, MS05-047, MS05-050 and MS05-052.

McAfee IntruShield will add protection against the vulnerabilities disclosed in MS05-044, MS05-046, MS05-047, MS05-048, MS05-050, MS05-051, MS05-052 and certain vulnerabilities disclosed in MS05-049. The updated signatures are included in signature sets 1.8.61, 1.9.44, 2.1.27 and later, which will be available for download on October 11, 2005. McAfee IntruShield sensors deployed in in-line mode can be configured with a response action to drop such packets for preventing these attacks.

McAfee Foundstone checks have been created that will detect these vulnerabilities and will be available in the package released on October 11, 2005.

The McAfee System Compliance Profiler, a component of McAfee ePolicy Orchestrator, is being updated to quickly assess compliance levels of Microsoft security patches for MS05-044, MS05-045 and MS05-047 through
MS05-052 announced today.

As new exploits are discovered, McAfee AVERT will add detection and removal to the DATs. The 4562 DAT files protect against known attacks against MS05-052. McAfee users can refer to for information regarding any new threats attempting to exploit these vulnerabilities.
