[R1] Nessus 8.13.2 Fixes Multiple Third-party Vulnerabilities
Medium
Synopsis
Nessus 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 good practice, Tenable opted to upgrade the
bundled OpenSSL components to address the potential impact of these issues.
Nessus 8.13.2 updates OpenSSL to version 1.1.1k to address the identified
vulnerabilities.
Solution
Tenable has released Nessus 8.13.2 to address these issues. The installation
files can be obtained from the Tenable Downloads Portal ( https://
www.tenable.com/downloads/nessus ).
