Are you infected?
TEST IT:

Test 1: https://www.ssllabs.com/ssltest/
Test 2: https://test.drownattack.com/

Now we have to understand if Webuzo Team MUST release immediately an update.
This is flagged as very Hight security issue... or if is misconfiguration of user but I think is not this.

Hi,

We have added the latest exim rpm into our repository. To resolve this issue you will now have to re-install exim on your server.

Please let us know if you need any further information. We will be happy to help you.

This is now solved.

For fix this issue you should backup your Exim configuration.
You can do this by using FTPS and download Exim folder in etc
or you can just backup the file exim.conf

After that you need go on Webuzo, Apps and search Exim than remove exim.
If you have customized Exim you will loose customized settings, this is why backup is important.

After removing, please reinstall it.

Now in exim.conf under

tls_certificate = /etc/pki/tls/certs/exim.pem
tls_privatekey = /etc/pki/tls/private/exim.pem

you can add this row:

openssl_options = +no_sslv2 +no_sslv3

than exit and restart exim

You are safe now

Many thanks to CentOs support, RedHat support and Webuzo Team... and also to me who discovered this and also new vulnerability in this week end.
