More information

SVG is issuing this alert as we are aware that some sites in the infrastructure are using Salt 
and the issue is described by the software providers as 'CRITICAL' [R 1].  From their description 
this fits with our criteria for a  vulnerability we would assess as 'CRITICAL'.  
We are also aware that these vulnerabilities are currently being actively exploited, 
so sites running Salt need to take action urgently.
