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 Agent 10.4.3 updates OpenSSL to version
3.0.12 and zlib fixes have been applied to address the identified vulnerabilities.
Additionally, one other vulnerability was discovered, reported and fixed:
- CVE-2023-5847: Under certain conditions, a low privileged attacker could load a specially
crafted file during installation or upgrade to escalate privileges on Windows and Linux hosts.");
