Vendor Statements (disclaimer)

Official Statement from Red Hat (03/25/2008)

Red Hat do not consider this to be a security issue and there are many ways that you can identify or fingerprint a Linux machine. Users that wish to block fingerprinting can use various techniques to disguise their operating system, for example see http://www.infosecwriters.com/text_resources/pdf/nmap.pdf
