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, according to the EGI SVG issue handling procedure [R 4]  
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.
