725657 – net-snmp should be compiled with relro

RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Jan Safranek 2011-07-26 08:15:38 UTC

Description of problem:
Steve Grubb's mighty check shows that net-snmp is not compiled with relro.

Version-Release number of selected component (if applicable):
net-snmp-5.5-31.el6.x86_64

How reproducible:
always

Steps to Reproduce:
1. download http://people.redhat.com/sgrubb/files/rpm-chksec
2. yum install net-snmp net-snmp-perl net-snmp-utils
3. for i in net-snmp{,-libs,-utils,-perl}; do ./rpm-chksec $i; done
  
Actual results:
something is red

Expected results:
everything is green

Perl and python modules take LDFLAGS from net-snmp-config, which does not contain relro options... Recompilation is necessary.

Comment 8 Karel Srot 2011-09-06 10:48:21 UTC

retested with net-snmp-5.5-36.el6, there are two libs remaining without relro.

/usr/lib/perl5/vendor_perl/auto/NetSNMP/agent/default_store/default_store.solibrary   no       DSO
/usr/lib/python2.6/site-packages/netsnmp/client_intf.so library   no       DSO
