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

Medium Nessus Plugin ID 89923


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


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.
