The wrappers report the name of the client host and of the -requested service; the wrappers do not exchange information with the -client or server applications, and impose no overhead on the actual -conversation between the client and server applications. - -This patch upgrades the tcp wrappers version 7.5 source code to -version 7.6. The source-routing protection in version 7.5 was not -as strong as it could be. And all this effort was not needed with -modern UNIX systems that can already stop source-routed traffic in -the kernel. Examples are 4.4BSD derivatives, Solaris 2.x, and Linux. - -This release does not introduce new features. Do not bother applying -this patch when you built your version 7.x tcp wrapper without -enabling the KILL_IP_OPTIONS compiler switch; when you can disable -IP source routing options in the kernel; when you run a UNIX version -that pre-dates 4.4BSD, such as SunOS 4. Such systems are unable to -receive source-routed connections and are therefore not vulnerable -to IP spoofing attacks with source-routed TCP connections. - -A complete change log is given in the CHANGES document. As always, -problem reports and suggestions for improvement are welcome. - - Wietse Venema (wietse@wzv.win.tue.nl), - Department of Mathematics and Computing Science, - Eindhoven University of Technology, - The Netherlands. - - Currently visiting IBM T.J.
