Technical Details:
OpenSSH is OpenBSD's SSH (Secure Shell)
protocol implementation. These Linux Distribution Packages include the core files necessary for
both the OpenSSH client and server.
It was discovered that the OpenSSH server did not sanitize data received
in requests to enable X11 forwarding. An authenticated client with
restricted SSH access could possibly use this flaw to bypass intended
restrictions. (CVE-2016-3115)
An access flaw was discovered in OpenSSH the OpenSSH client did not
correctly handle failures to generate authentication cookies for untrusted
X11 forwarding. A malicious or compromised remote X application could
possibly use this flaw to establish a trusted connection to the local X
server, even if only untrusted X11 forwarding was requested.
(CVE-2016-1908)
All openssh users are advised to upgrade to these updated Linux Distribution Packages, which
contain backported patches to correct these issues. After installing this
update, the OpenSSH server daemon (sshd) will be restarted automatically.

What's vulnerability management?
Vulnerability management is the process in which vulnerabilities in IT are identified and the risks of these vulnerabilities are evaluated. This evaluation leads to correcting the vulnerabilities and removing the risk or a formal risk acceptance by the management of an organization. The term vulnerability management is often confused with vulnerability scanning. Despite the fact both are related, there is an important difference between the two. Vulnerability scanning consists of using a computer program to identify vulnerabilities in networks, computer infrastructure or applications. Vulnerability management is the process surrounding vulnerability scanning, also taking into account other aspects such as risk acceptance, remediation etc. Source: "Implementing a Vulnerability Management Process".
