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 Filip Krska 2019-02-25 10:04:44 UTC 
Description of problem:

snmptrapd crashes when forwarding SNMPv3 notifications

Version-Release number of selected component (if applicable):

net-snmp-5.7.2-37.el7

How reproducible:

Always

Steps to Reproduce:
1. cat /etc/snmp/snmptrapd.conf

createUser testuser SHA pwdpwdpwd AES pwdpwdpwd
authUser log,execute,net testuser noauth

disableAuthorization yes

forward default localhost:3000

2. systemctl restart snmptrapd.service

3. cat /tmp/snmptrapd2.conf 

createUser testuser SHA pwdpwdpwd AES pwdpwdpwd
authUser log,execute,net testuser noauth

snmpTrapdAddr 0.0.0.0:3000


4. snmptrapd -f -C -c /tmp/snmptrapd2.conf -Le &

5. snmptrap -Ci -v3 -u testuser -l noAuthNoPriv localhost 0 linkUp.0


Actual results:

# systemctl status snmptrapd.service
● snmptrapd.service - Simple Network Management Protocol (SNMP) Trap Daemon.
   Loaded: loaded (/usr/lib/systemd/system/snmptrapd.service; disabled; vendor preset: disabled)
   Active: failed (Result: signal) since Mon 2019-02-25 04:58:50 EST; 9s ago
  Process: 14163 ExecStart=/usr/sbin/snmptrapd $OPTIONS -f (code=killed, signal=SEGV)
 Main PID: 14163 (code=killed, signal=SEGV)


Expected results:

no segfault

Additional info:

Backtrace pattern same as in upstream report:

https://sourceforge.net/p/net-snmp/mailman/message/27984692/

Didn't reproduce with net-snmp-5.8-6.fc30.x86_64.rpm, net-snmp-5.8-7.el8.x86_64

Wasn't successful with identifying chunk which fixed the issue, corresponding Changelog entry so far, probably side effect of another fix/feature.
Comment 1 Filip Krska 2019-02-25 13:22:16 UTC 
snmpinform -Ci -v3 -u testuser -l noAuthNoPriv localhost 0 linkUp.0

leads to crash as well...
