Description Alexander Todorov 2015-09-17 07:26:17 EDT
Description of problem:


FESCo requires some packages to use PIE and relro hardening by default. This page contains that list:
https://fedoraproject.org/wiki/Hardened_Packages

sendmail-milter uses only Partial RELRO instead of Full RELRO. Please comment if this is acceptable or should be changed ? 

----------

Partial RELRO   Canary found      NX enabled    DSO             No RPATH   No RUNPATH   ./usr/lib64/libmilter.so.1.0.1
Comment 1 Jaroslav Škarvada 2015-09-23 11:57:59 EDT
It makes sense, binaries linking libmilter are usually long running processes processing untrusted data.
