Context
=======
This advisory has been prepared as part of the effort to fulfil EGI SVG's
purpose "To minimize the risk to the EGI infrastructure arising from software
vulnerabilities"
The risk is that assessed by the group, in the context of how the software is
used in the EGI infrastructure. It is the opinion of the group, we do not
guarantee it to be correct.
The risk may also be higher or lower in other deployments depending on how the
software is used.
This was handled according to the EGI SVG issue handling procedure [R 1] which
has since been replaced by [R 2] approved by the Operations Management Board in
November 2017.
