Red Hat Security Advisory
Synopsis: Moderate: Red Hat OpenStack Platform 17.1 (python-paramiko) security update
Advisory ID: RHSA-2024:2735-03
Product: Red Hat OpenStack Platform
Advisory URL: https://access.redhat.com/errata/RHSA-2024:2735
Issue date: 2024-05-22
Revision: 03
CVE Names: CVE-2023-48795
====================================================================
Summary:
An update for python-paramiko is now available for Red Hat OpenStack
Platform 17.1 (Wallaby).
Red Hat Product Security has rated this update as having a security impact
of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which
gives a detailed severity rating, is available for each vulnerability from
the CVE link(s) in the References section.
Description:
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):
* Prefix truncation attack on Binary Packet Protocol (BPP) (CVE-2023-48795)
For more details about the security issue(s), including the impact, a CVSS
