Update March 25, 2021

16:00 | OpenSSL published today the patch for two critical vulnerabilities (CVE-2021-3450 and CVE-2021-3449). All OpenSSL services from version 1.1.1h must be patched. Without this patch, a denial-of-service (DoS) attack is possible. A denial-of-service attack (DoS attack) is a cyber-attack in which the perpetrator seeks to make a machine or network resource unavailable to its intended users by temporarily or indefinitely disrupting services of a host connected to the Internet. It is quite easy to disrupt the systems behind your unpatched OpenSSL with a script. You solve this by patching.
