New! Plugin Severity Now Using CVSS v3

Synopsis

The remote FreeBSD host is missing a security-related update.

Description

There is a bug in SSH2 support that allows a server to execute malicious code on a connecting PuTTY client. This attack can be performed before host key verification happens, so a different machine
-- man in the middle attack -- could fake the machine you are connecting to.

Solution

Update the affected package.
