OpenSSL is an open-source toolkit for encrypted communications, so its vulnerabilities and security updates can affect software, servers, and data protection.

Background for this topic.
OpenSSL is an open-source cryptographic library and command-line toolkit used to implement Transport Layer Security (TLS), the protocol that protects network connections. It provides cryptographic algorithms, key generation, certificate and X.509 handling, and APIs used by operating systems, servers, applications, and embedded devices. Although commonly associated with “SSL,” the obsolete SSL protocols should not be enabled; modern deployments use TLS.
OpenSSL vulnerabilities can affect many dependent applications, particularly when flaws involve memory handling, cryptographic operations, certificate parsing, or TLS protocol processing. Security teams need an inventory of software and devices that include the library, because updating a package or operating-system component may be necessary even when OpenSSL is not directly visible. Advisories should be assessed against the deployed version, enabled features, and exposure, while private keys require strict protection and certificate validation must be configured correctly. Vulnerability remediation may also require restarting services or replacing processes that continue to use an older library in memory.

Experts still recommend patching affected systems
Relax, there's more chance of Babbage coming back to life to hack your system than this flaw being exploited OpenSSL today issued a fix for a critical-turned-high-severity vulnerability that project maintainers warned about last week. …
Organizations should update to the latest encryption (version 3.0.7) as soon as possible, but there's no need for Heartbleed-like panic, security experts say.
That bated-breath OpenSSL update is out! It's no longer rated CRITICAL, but we advise you to patch ASAP anyway. Here's why...
The OpenSSL Project has patched two high-severity security flaws in its open-source cryptographic library used to encrypt communication channels and HTTPS connections. [...]
The OpenSSL project has rolled out fixes to contain two high-severity flaws in its widely used cryptography library that could result in a denial-of-service (DoS) and remote code execution
As everyone waits for news of a bug in OpenSSL, here's a reminder that other cryptographic code in your life may also need patching!
