Description

Trojaned PuTTY builds have become more common recently, one method to catch some of them is to look for the version string. Current master does not always allow this since : is not a valid character for ssh.softwareversion. (ex. Putty-Local: Timestamp HH:MM:SS)

I made a pull request on GitHub regarding the issue at https://github.com/inliniac/suricata/pull/1491
