The following glibc security update is now available from
nethserver-updates YUM repository:
https://rhn.redhat.com/errata/RHSA-2015-0092.html
As usual, to update your system type as root:
# yum clean all
# yum update
Once this update has been applied, reboot your instance to ensure that
all processes and daemons that link against glibc are using the updated
version.
