Critical
← View More Security Advisories

Synopsis

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

Out of caution, and in line with best practice, Tenable opted to upgrade the bundled OpenSSL components to address the potential impact of these issues. Tenable.sc patch SC-202109.1 updates OpenSSL to version 1.1.1l to address the identified vulnerabilities.

Solution

Tenable has released Tenable.sc Patch SC-202109.1 to address these issues. The installation files can be obtained from the Tenable Downloads Portal (https://www.tenable.com/downloads/tenable-sc).
