RHEL 8 : Red Hat OpenStack Platform 16.1.9 (python-paramiko) (RHSA-2022:8863)

medium Nessus Plugin ID 170387

Language:

Synopsis

The remote Red Hat host is missing a security update for Red Hat OpenStack Platform 16.1.9 (python-paramiko).

Description

The remote Redhat Enterprise Linux 8 host has a package installed that is affected by a vulnerability as referenced in the RHSA-2022:8863 advisory.

 Paramiko (a combination of the esperanto words for paranoid and friend) is a module for python 2.3 or greater that implements the SSH2 protocol for secure (encrypted and authenticated) connections to remote machines. Unlike SSL (aka TLS), the SSH2 protocol does not require heirarchical certificates signed by a powerful central authority. You may know SSH2 as the protocol that replaced telnet and rsh for secure access to remote shells, but the protocol also includes the ability to open arbitrary channels to remote services across an encrypted tunnel. (This is how sftp works, for example.)

 Security Fix(es):

 * 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 listed in the References section.

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.

Solution

Update the RHEL Red Hat OpenStack Platform 16.1.9 (python-paramiko) package based on the guidance in RHSA-2022:8863.
