Update to latest upstream release, includes several security related fixes.

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora update system website.
Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

According to its self-reported version, the Nessus Network Monitor running on the remote host is prior to 6.2.2. It is, therefore, affected by multiple vulnerabilities as referenced in the TNS-2023-23 advisory. Several of the third-party components 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 opted to upgrade these components to address the potential impact of the issues. Nessus Network Monitor 6.2.2 updates the following components:

  - c-ares from version 1.10.0 to version 1.19.1.
  - curl from version 7.79.1 to version 8.1.2.
  - libbzip2 from version 1.0.6 to version 1.0.8.
  - libpcre from version 8.42 to version 8.44.
  - libxml2 from version 2.7.7 to version 2.11.1.
  - libxslt from version 1.1.26 to version 1.1.37.
  - libxmlsec from version 1.2.18 to version 1.2.37.
  - sqlite from version 3.27.2 to version 3.40.1.
  - jQuery Cookie from version 1.3.1 to version 1.4.1.
  - jQuery UI from version 1.13.0 to version 1.13.2.
  - OpenSSL from version 3.0.8 to version 3.0.9.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - The htmlCurrentChar function in libxml2 before 2.9.4, as used in Apple iOS before 9.3.2, OS X before     10.11.5, tvOS before 9.2.1, and watchOS before 2.2.1, allows remote attackers to cause a denial of service     (heap-based buffer over-read) via a crafted XML document. (CVE-2016-1833)

Note that Nessus relies on the presence of the package as reported by the vendor.
