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 of problem:

The "net-snmp-cert gencert" tool generates certificates signed by obsolete SHA1.

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

net-snmp-perl-1:5.8-17.el8.x86_64

How reproducible:

Always

Steps to Reproduce:
1. Generate a server certificate:

[root@localhost ~]# net-snmp-cert gencert -I -t snmpd -n hostname.example.com --san DNS:snmpd.example.com
Certificate Generated:
  certs/snmpd.crt
  private/snmpd.key

2. View the certificate generated:

[root@localhost tls]# openssl x509 -text -in /etc/snmp/tls/certs/snmpd.crt

Actual results:

Signature Algorithm: sha1WithRSAEncryption

Expected results:

SHA256 at least.

Additional info:

Client certificate has the same problem:

net-snmp-cert gencert -I -t manager -n joecool --san email:cooljoe.com
