    Hello, OpenSSH and OpenSSL are packages that are provided by your OS (e.g. CentOS). You can update your system packages to the latest versions offered by your OS with the "yum update" command. Additionally, you can see which security patches have been backported in the version your OS provides with a command such as this:
    rpm -q --changelog openssh | grep CVE
    Thank you.

    Yes, the version you provided matches what's installed on a test system running CentOS 7.3. You can also use the below command to verify the patches that have been backported:
    rpm -q --changelog openssh | grep CVE
    Here's what the output looks like on a CentOS 7.3 system:
    ]# rpm -q --changelog openssh | grep CVE - CVE-2015-8325: privilege escalation via user's PAM environment and UseLogin=yes (#1329191) - CVE-2016-1908: possible fallback from untrusted to trusted X11 forwarding (#1298741) - CVE-2016-3115: missing sanitisation of input for X11 forwarding (#1317819) - prevents CVE-2016-0777 and CVE-2016-0778 - Security fixes released with openssh-6.9 (CVE-2015-5352) (#1247864) - only query each keyboard-interactive device once (CVE-2015-5600) (#1245971) - add new option GSSAPIEnablek5users and disable using ~/.k5users by default CVE-2014-9278 - prevent a server from skipping SSHFP lookup - CVE-2014-2653 (#1081338) - change default value of MaxStartups - CVE-2010-5107 (#908707) - CVE-2010-4755 - fixed audit log injection problem (CVE-2007-3102) - CVE-2006-5794 - properly detect failed key verify in monitor (#214641) - CVE-2006-4924 - prevent DoS on deattack detector (#207957) - CVE-2006-5051 - don't call cleanups from signal handler (#208459) - use fork+exec instead of system in scp - CVE-2006-0225 (#168167)
