Description of the patch
This update for libssh2_org fixes the following issues:
Security issue fixed:
- 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.
A feature was added:
- Support of SHA256 digests for DH group exchanges was added (fate#320343, bsc#961964)
Bug fixed:
- Properly detect EVP_aes_128_ctr at configure time (bsc#933336)
