Regardless of being patched promptly (and regardless of dependable workarounds current for builders who couldn’t or wouldn’t replace their weak OpenSSL variations shortly), Heartbleed stays a form of “showcase” bug, not least as a result of it was one of many first bugs to be become an aggressive PR car by its discoverers.

With a formidable identify, a emblem all of its personal, and a devoted web site, Heartbleed shortly turned a world cybersecurity superstory, and, for higher or worse, turned inextricably linked with mentions of the identify OpenSSL, as if the hazard of the bug lived on even after it had been excised from the code.

Life past OpenSSL

However there are a number of different open-source cryptographic libraries which might be extensively used in addition to or as a substitute of OpenSSL, notably together with Mozilla’s NSS (brief for Community Safety Providers) and the GNU venture’s GnuTLS library.

Because it occurs, GnuTLS simply patched a bug referred to as CVE-2022-2509, reported within the venture’s safety advisory GNUTLS-SA-2022-07-07.
