If sites find they are running a vulnerable version of OpenSSL they should 
consider updating to avoid a DoS at their sites. 

If anyone becomes aware of any situation where this vulnerability has a 
significant impact on the EGI infrastructure then please inform EGI SVG.

RHEL7 and RHEL8 and derivatives do not appear to be affected  [R 2] 

Ubuntu [R 3] and Debian [R 4] have some limited exposure.

More information

The EGI SVG is issuing this INFORMATION because some sites are asking about 
it, it is being talked about a lot,  and other infrastructures are issuing 
an advisory. 

The EGI SVG considers the possibility of a DoS at one site to be less serious 
than, for example, a privilege escalation vulnerability. 

The combination of this being a DoS and their being little likelihood of many 
sites being affected means it is not considered to be a serious risk to EGI.
