Fedora 22: openssh Security Update 2015-11063
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.
Update Information:
This update brings security fix for two announced vulnerabilities. Namely XSECURITY restrictions bypass under certain conditions AND weakness of agent locking (ssh-add -x) to password guessing (more info in related bugs). It also provides new version of openssh-6.9 which is bringing many bugfixes and few new features with maintaining compatibility with previous version.
