Synopsis :

The remote EulerOS host is missing a security update.

Description :

According to the version of the libssh2 package installed, the
EulerOS installation on the remote host is affected by the following
vulnerability :

- A type confusion issue was found in the way libssh2
generated ephemeral secrets for the
diffie-hellman-group1 and diffie-hellman-group14 key
exchange methods. This would cause an SSHv2
Diffie-Hellman handshake to use significantly less
secure random parameters. (CVE-2016-0787)

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.
