CentOS 6, Exim-4.94.2, CVE-2020-28007+


May 24, 2002

Recently new version of exim-4.94.2 was published. It have a lot of security fixes.

I have an old server with CentOS 6.
I know CentOS 6 not supported for now. But I have to use it by some reasons.

I see CPanel updated exim recently
# cat /etc/redhat-release
CentOS release 6.10 (Final)
# exim --version
Exim version 4.93 #2 built 03-May-2021 19:32:37

Does this release have all the security fixes?

Can someone tell me for sure?
In the CPanel change log I see
Change Log for 86.0.40
