## Symptoms

- [Qualys Security team](https://www.qualys.com/2016/01/14/cve-2016-0777-cve-2016-0778/openssh-cve-2016-0777-cve-2016-0778.txt) discovered two vulnerabilities in the roaming code of the OpenSSH client ([CVE-2016-0777](https://www.cve.org/CVERecord?id=CVE-2016-0777) and [CVE-2016-0778](https://www.cve.org/CVERecord?id=CVE-2016-0778)):
SSH roaming enables a client, in case an SSH connection breaks unexpectedly, to resume it at a later time, provided the SSH server also supports it.

## Solution

The exploitation scenario is only applicable to OpenSSH client that connects to a malicious SSH Server (e.g., refer to [OpenBSD Journal - OpenSSH: client bugs CVE-2016-0777 and CVE-2016-0778](http://undeadly.org/cgi?action=article&sid=20160114142733)).

Check Point Products are ***not*** vulnerable because a hardened OpenSSH is used (based on version 4.3).
