RHEL/CentOS 6 OpenSSL client compatibility after DST Root CA X3 expiration

As @joconcha indicated you need to install the packages using RPM at the same time as they are interdependent. If you look at rpm -qa openssl\* you should see what is already installed. openssl-libs is a new package since EL7, though, so you'll definitely need to add that to the list. Then, just install the same package files for the new version. I had to install openssl, openssl-libs, and openssl-devel to satisfy the dependencies.
