The remote Red Hat host is missing one or more security updates.
An update for libssh is now available for Red Hat Enterprise Linux 7
Red Hat Product Security has rated this update as having a security
impact of Moderate. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available for each
vulnerability from the CVE link(s) in the References section.
libssh is a library which implements the SSH protocol. It can be used
to implement client and server applications.
Security Fix(es) :
* A type confusion issue was found in the way libssh 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
Red Hat would like to thank Aris Adamantiadis for reporting this
