Mariusz Ziulek reported that libssh2, a SSH2 client-side library, was reading
and using the SSH_MSG_KEXINIT packet without doing sufficient range checks
when negotiating a new SSH session with a remote server. A malicious attacker
could man in the middle a real server and cause a client using the libssh2
library to crash (denial of service) or otherwise read and use unintended
memory areas in this process (CVE-2015-1782).");
