TPS-2016-002 OpenSSH CVE-2016-0777 and CVE-2016-0778

Overview Two new vulnerabilities in the OpenSSH SSH client (CVE-2016-0777 and CVE-2016-0778) allow a malicious or compromised SSH server to induce the client to leak arbitrary memory (including the client’s private keys), and, in some versions of the client, execute arbitrary code on the client system. The client checks the server’s host keys before reaching the point of vulnerability, so a man-in-the-middle attack is not a realistic vector (unless the server’s host keys have already been disclosed).
