[R1] Stand-alone Security Patch Available for Tenable.sc versions 5.19.0 to
5.20.1: Patch 202204.1



Tenable.sc leverages third-party software to help provide underlying
functionality. Two of the third-party components (Apache and OpenSSL) were
found to contain vulnerabilities, and updated versions have been made available
by the providers.

Out of caution, and in line with best practice, Tenable has upgraded the
bundled components to address the potential impact of these issues. Tenable.sc
Patch 202204.1 updates OpenSSL to version 1.1.1n and Apache to version 2.4.53
to address the identified vulnerabilities.


Tenable has released Tenable.sc Patch 202204.1 to address these issues. The
installation files can be obtained from the Tenable Downloads Portal ( https://
www.tenable.com/downloads/tenable-sc ).
