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 Alicja Kario 2021-02-04 12:25:14 UTC 
Description of problem:
The documentation for crypto-policies:
https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/8/html/security_hardening/using-the-system-wide-cryptographic-policies_security-hardening
https://access.redhat.com/articles/3642912
says that Camellia is disabled evrywhere. That is not the case for Kerberos, at least camellia256-cts-cmac and camellia128-cts-cmac are still active there

# man crypto-policies

       Cipher suites and protocols disabled in all policy levels

       The following ciphersuites and protocols are available but disabled in all 
       crypto policy levels. They can be enabled only by explicit configuration
       of individual applications:

       ·   DH with parameters < 1024 bits
       ·   RSA with key size < 1024 bits
       ·   Camellia
       ·   ARIA
       ·   SEED
       ·   IDEA
       ·   Integrity only ciphersuites
       ·   TLS CBC mode ciphersuites using SHA-384 HMAC
       ·   AES-CCM8
       ·   all ECC curves incompatible with TLS 1.3, including secp256k1

NEW (crypto-policies-20210617-1.gitc776d3e.el8.noarch)
======================================================
# man crypto-policies
...
       Cipher suites and protocols disabled in all predefined policies

       The following ciphersuites and protocols are available but disabled in all 
       predefined crypto policies. They can be enabled only by explicit
       configuration of individual applications:

       ·   DH with parameters < 1024 bits
       ·   RSA with key size < 1024 bits
       ·   ARIA
       ·   SEED
       ·   IDEA
       ·   Integrity only ciphersuites
       ·   TLS CBC mode ciphersuites using SHA-384 HMAC
       ·   AES-CCM8
       ·   all ECC curves incompatible with TLS 1.3, including secp256k1
       ·   IKEv1
...

Also, this man page now correctly mentions Camellia in non-TLS Ciphers only for LEGACY and DEFAULT policies.
