The remote Redhat Enterprise Linux 8 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2022:4712 advisory.
The ovirt-engine package provides the Red Hat Virtualization Manager, a centralized management platform that allows system administrators to view and manage virtual machines. The Manager provides a comprehensive range of features including search capabilities, resource management, live migrations, and virtual infrastructure provisioning.
The ovirt-ansible-hosted-engine-setup package provides an Ansible role for deploying Red Hat Virtualization Hosted-Engine.
Security Fix(es):
* python-paramiko: Race condition in the write_private_key_file function (CVE-2022-24302)
For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
A list of bugs fixed in this update is available in the Technical Notes book:
https://access.redhat.com/documentation/en-us/red_hat_virtualization/4.4/html-single/technical_notes
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.
