[-- Attachment #1 --] From the Makefile... # It is important that nologin be statically linked for security # reasons. A dynamic non-setuid binary can be linked against a trojan # libc by setting LD_LIBRARY_PATH appropriately. Both sshd(8) and # login(1) make it possible to log in with an unsanitized environment, # rendering a dynamic nologin binary virtually useless.
