OVERVIEW:

        A vulnerability has been identified in McAfee E-Business Server, 
        which if successfully exploited can result in the execution of
        arbitrary code or a denial of service (DoS).

        This vulnerability only exists in the Windows version.


IMPACT:

        McAfee has published the following details regarding this 
        vulnerability:

        "A vulnerability exists in McAfee E-Business Server. A successful 
        exploit of the security flaw would allow an attacker to remotely 
        execute code or crash the running service. In order to accomplish 
        this exploit, an attacker must send specially modified network 
        traffic to the server. When the server processes this malicious 
        traffic, the service will interrupt normal functioning of the server 
        and may execute code with the same privileges as the LOCAL_SYSTEM 
        service." [1]

        Proof of concept for this vulnerability has been publicly published. 
         

MITIGATION:

        E-Business Server 8.5.3 for Windows has been released and is now 
        available for download.[2]
