About preparation of binaries. Some security features of preparation of Red Hat EL4 are
mentioned in this document:
http://people.redhat.com/drepper/nonselsec.pdf
Also in this Red Hat EL5 "What's new" document:
http://www.redhat.com/f/pdf/rhel/rhel5_whatsnew.pdf
it is mentioned:
"Red Hat Enterprise Linux 5 is built using the latest version of the industry-standard GNU
Compiler Collection toolchain. The distribution is built using the fortify-source compiler
flag, which provides more stringent run-time buffer bounds checking, thereby adding to
overall system security."
This is what has happened to come across. I haven't searched thoroughly for preparation
security options.
