Dist Fedora Esm H88
Crucial patch for Fedora 22: gsi-openssh mitigates vulnerabilities through updated package synchronization and enhanced threat protection.
Sync with latest openssh package.

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 version of OpenSSH has been modified to support GSI authentication.

This package includes the core files necessary for both the gsissh

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

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

Update Information:

Sync with latest openssh package.
