Scientific Linux Security Update : libssh2 on SL6.x, SL7.x i386/x86_64

This script is Copyright (C) 2016 Tenable Network Security, Inc.


Synopsis :

The remote Scientific Linux host is missing one or more security
updates.

Description :

A type confusion issue was found in the way libssh2 generated
ephemeral secrets for the diffie-hellman-group1 and
diffie-hellman-group14 key exchange methods. This would cause an SSHv2
Diffie-Hellman handshake to use significantly less secure random
parameters. (CVE-2016-0787)

After installing these updated packages, all running applications
using libssh2 must be restarted for this update to take effect.
