It was found that Red Hat JBoss Core Services erratum RHSA-2016:2957 for CVE-2016-3705 did not actually include the fix for the issue found in libxml2, making it vulnerable to a Denial of Service attack due to a Stack Overflow. This is a regression CVE for the same issue as CVE-2016-3705.

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.
