A new vulnerability in glibc was recently announced currently going by the name of GHOST. You can find more info here:
The problem can be triggered remotely through the gethostbyname function. This problem is not specific to the perfSONAR Toolkit and has the potential to impact many common Linux services. The RedHat announcement can be found here:
Users may run 'yum update' to get the package or if you have auto-updates enabled you will get the package sometime in the next 24 hours. Note that even if auto-updates are enabled it is HIGHLY recommended to manually reboot the host. glibc is a rather ubiquitous library so rebooting is the best way to ensure there are no services running still using the old library.

Version 3.3 of perfSONAR & LiveCD/LiveUSB EOL Announcement
Posted January 5, 2015
perfSONAR version 3.3, and the LiveCD and LiveUSB products, will be EOLed on April 10th, 2015. All users must upgrade to version 3.4 by this date, or risk using unsupported software.
Those sites that are using the LiveCD/LiveUSB can upgrade using this documentation:
For individuals who would like to have access to the historic
RPMs, the project has created a "vault" containing last builds of
project software from prior versions:
The Internet2 repository software (versions 0.4-2 and above for version 3.3 users) contains directives to enable this feature. The repository package can be found in these locations, or will be updated for existing installation via YUM:
Once enabled, the vault will allow existing toolkit builds to access the old RPMs. However, it will not allow someone to install a fresh instance from a netinstall ISO. To enable this repo:
a) Edit the "/etc/yum.repos.d/Internet2-Vault.repo" file and change "enabled = 0" to "enabled = 1" for both repositories listed in this file
b) Run 'yum update' to update the cache of packages
perfSONAR via Docker
Posted December 18, 2014
The perfSONAR Project is experimenting with docker. For those that are curious, the "perfSONAR_PS-Bundles-Level1" product () is now available at this location:
The main use case for this container is to let you run a minimal perfSONAR setup on an alternate Linux distribution other than RHEL/CentOS, such as Debian, Ubuntu, or SUSE, without needing to build everything from source.
