EulerOS 2.0 SP1 : openssh (EulerOS-SA-2016-1008)

This script is Copyright (C) 2017 Tenable Network Security, Inc.


Synopsis :

The remote EulerOS host is missing multiple security updates.

Description :

According to the versions of the openssh packages installed, the
EulerOS installation on the remote host is affected by the following
vulnerabilities :

- 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)

Note that Tenable Network Security has extracted the preceding
description block directly from the EulerOS security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.
