SUSE SLED11 / SLES11 Security Update : libssh2_org (SUSE-SU-2016:0723-1)

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


Synopsis :

The remote SUSE host is missing one or more security updates.

Description :

This update for libssh2_org fixes the following issues :

- Add SHA256 support for DH group exchange (fate#320343,
bsc#961964)

- fix CVE-2016-0787 (bsc#967026)

- Weakness in diffie-hellman secret key generation lead to
much shorter DH groups then needed, which could be used
to retrieve server keys.

Note that Tenable Network Security has extracted the preceding
description block directly from the SUSE security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.
