✅ Remediation

For details on how to apply this update, which includes the changes described in this advisory, refer to: https://images.redhat.com/ Workaround: To mitigate this issue, administrators should ensure that the `pam_userdb` module is not configured to store or compare credentials in plaintext. Verify that `pam_userdb` is either configured with a strong cryptographic hashing method or, if not required, is disabled. Avoid using `crypt=none` or omitting the `crypt=` argument when configuring `pam_userdb`. If changes are made to PAM configuration files, services relying on PAM may need to be restarted for the changes to take effect.
