VMware vSphere ESXi 5.1


Summaries and Symptoms

This patch updates the following issues:

  • Support for SSLv3 protocol is enabled by default and is configurable.

    Note: To disable SSLv3 in your vSphere environment, you need to update ESXi to ESXi 5.1 patch [3872664] released on 05/24/2016 and update vCenter Server to vCenter Server 5.1 Update 3d first and then manually disable SSLv3 through configuration settings, for more information, see KB 2139396.

    ESXi hosts updated to ESXi 5.1 patch [3872664] released on 05/24/2016 can be managed by older vCenter Server only if SSLv3 is not disabled in ESXi hosts.

    VMware highly recommends you to update ESXi hosts to ESXi 5.1 patch [3872664] while managing them from vCenter Server 5.1 Update 3d.

    The following products might not work if SSLv3 is disabled in vSphere 5.1 environment:

    • Site Recovery Manager
    • Big Data Extensions
    For more information on products eligible for SSLv3 disablement with vSphere 5.1, see KB 2145484.

  • The Python third-party library is updated to version 2.7.9.
  • The ESXi userworld libxml2 library is updated to version 2.9.2.
  • When you start the Autodeploy service to deploy certificates, outdated SHA1 signature might be used.
  • The OpenSSH is updated to version OpenSSH 7.1p1 Open SSH is updated to version 7.1.
  • The ESXi OpenSSL library is updated to version openssl0.98.
