The remote Redhat Enterprise Linux 6 / 7 / 8 / 9 host has a package installed that is affected by a vulnerability as referenced in the RHSA-2024:2011 advisory.

Red Hat Satellite is a system management solution that allows organizations     to configure and maintain their systems without the necessity to provide     public Internet access to their servers or other client systems. It     performs provisioning and configuration management of predefined standard     operating environments.

Security fix:
* puppet-agent: curl heap based buffer overflow in the SOCKS5 proxy handshake (CVE-2023-38545)

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
