socat: default DH parameters should be larger
Last modified: 2017-10-03 21:24:53 EDT
At least a 1024 bit prime should be used as the default. Generating a file with the parameters at installation time might not be feasible, but it would prevent any appearance of choosing a special prime that makes the discrete logarithm problem feasible.

this fix is in 18.104.22.168 as well
Any update, why don't we upgrade socat?
+1 for this, socat has also issues when used in MariaDB Galera cluster with SSL/TLS SST - https://jira.mariadb.org/browse/MDEV-9403
Please, rebase socat to latest stable 22.214.171.124 version.
I needed it for additional fun with MariaDB, so I've rebuilt the package with COPR: https://copr.fedorainfracloud.org/coprs/mstefany/socat/
