Fedora 39 rolls out a security patch that includes a crucial backport resolution for a significant SSH protocol vulnerability. Maintain your security!
Backport fix for CVE-2024-6387 (rhbz#2294879)

Summary

SSH (Secure SHell) is a program for logging into and executing

commands on a remote machine. SSH is intended to replace rlogin and

rsh, and to provide secure encrypted communications between two

untrusted hosts over an insecure network. X11 connections and

arbitrary TCP/IP ports can also be forwarded over the secure channel.

OpenSSH is OpenBSD's version of the last free version of SSH, bringing

it up to date in terms of security and features.

This package includes the core files necessary for both the OpenSSH

client and server. To make this package useful, you should also

install openssh-clients, openssh-server, or both.
