EMC Syncplicity Enterprise Edition on-premise storage account administrators are advised to patch their on-premise Storage Connector servers.  EMC recommends the following steps for each Storage Connector Node:

  1. Log into the Storage Connector node
  2. Check the version glibc with rpm by issuing the command “rpm -q glibc” (don't enter the quotes)
    The output should look like this, with the package name followed by version information:
    glibc-2.12-1.132.el6_5.4.x86_64
    If the version of glibc matches, or is more recent than, the one listed here, you are safe from the GHOST vulnerability:
    glibc-2.12-1.149.el6_6.5
  3. If the version of glibc is older than the one listed here, your system is vulnerable to GHOST and should be updated.
  4. Update glibc to the latest version available via yum by issuing the command “sudo yum update glibc” (don't enter the quotes)
  5. When the update is complete, reboot the Storage Connector server.
