[R1] Nessus Agent Version 10.4.1 Fixes Multiple VulnerabilitiesMedium
Synopsis
Nessus Agent 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 provider.
Out of caution and in line with best practice, Tenable has opted to upgrade
these components to address the potential impact of the issues. Nessus Agent
10.4.1 updates OpenSSL to version 3.0.9 to address the identified
vulnerabilities.
Solution
Tenable has released Nessus 10.4.1 to address these issues. The installation
files can be obtained from the Tenable Downloads Portal ( https://
www.tenable.com/downloads/nessus-agents ).
