✅ Remediation

For details on how to apply this update, which includes the changes described in this advisory, refer to: https://images.redhat.com/ Workaround: Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability. Workaround: To mitigate this issue, consider disabling GSSAPI authentication if it is not required, or reduce the `LogLevel` in the `sshd_config` file to a value lower than `SSH_LOG_PACKET` (e.g., `INFO`). To disable GSSAPI authentication, add or modify the following line in `/etc/ssh/sshd_config`: `GSSAPIAuthentication no` To reduce logging verbosity, add or modify the following line in `/etc/ssh/sshd_config`: `LogLevel INFO` After making changes to `sshd_config`, the `sshd` service must be restarted for the changes to take effect. This may temporarily interrupt active SSH sessions.
