Fedora 22 FEDORA-2015-12177 Critical OpenSSH Control Character Fix

Calendar Grey July 31, 2015
Dist Fedora Esm H88
A critical security patch for OpenSSH in Fedora 22 addresses issues regarding terminal control character management for safe communications.
Handle terminal control characters in scp progressmeter (#1247204) -- Security fix

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.
