   VMware ESX 4.1 without patches ESX410-201211401-SG,
                                  ESX410-201211402-SG,
                                  ESX410-201211405-SG, and

3. Problem Description

   a. VMware vSphere API denial of service vulnerability

      The VMware vSphere API contains a denial of service
      vulnerability.  This issue allows an unauthenticated user to
      send a maliciously crafted API request and disable the host
      daemon. Exploitation of the issue would prevent management
      activities on the host but any virtual machines running on the
      host would be unaffected.

      VMware would like to thank Sebastian Tello of Core Security
      Technologies for reporting this issue to us.
    
      The Common Vulnerabilities and Exposures project (cve.mitre.org)
      has assigned the name CVE-2012-5703 to this issue.

      Column 4 of the following table lists the action required to
      remediate the vulnerability in each release, if a solution is
      available.
