+++ This bug was initially created as a clone of Bug #1272537 +++ https://fedoraproject.org/wiki/Changes/Harden_All_Packages requires packages to be hardened (and also support hardening efforts). Currently, mcelog does not take advantage of all the hardening features we have in Fedora, and the attached patch tries to fix this. Before the hardening patch is applied, $ ./scanner.py ~/analysis/mcelog/upstream/ # contains RPMs from Rawhide mcelog,mcelog-101-2.9bfaad8f92c5.fc23.x86_64.rpm,/usr/sbin/mcelog,mode=0100755,NX=Enabled,CANARY=Enabled,RELRO=Partial,PIE=Disabled,RPATH=Disabled,RUNPATH=Disabled,FORTIFY=Partial$strncpy$memset$getcwd$read$fgets$memcpy$memmove$pread$asprintf,CATEGORY=network-local,TEMPPATHS=None,DEPS=libc.so.6 After the hardening patch is applied, $ ./scanner.py ~/analysis/mcelog/mine/ mcelog,mcelog-101-2.9bfaad8f92c5.fc24.x86_64.rpm,/usr/sbin/mcelog,mode=0100755,NX=Enabled,CANARY=Enabled,RELRO=Enabled,PIE=Enabled,RPATH=Disabled,RUNPATH=Disabled,FORTIFY=Partial$strncpy$memset$getcwd$read$fgets$memcpy$memmove$pread$asprintf,CATEGORY=network-local,TEMPPATHS=None,DEPS=libc.so.6 You can use https://fedoraproject.org/wiki/Changes/Harden_All_Packages#How_To_Test to verify if the patch is working for your builds too. --- Additional comment from Fedora End Of Life on 2016-11-24 07:48:44 EST --- Bug still present on Fedora 25.
This message is a reminder that Fedora 25 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 25. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '25'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 25 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
