✅ Remediation
For details on how to apply this update, which includes the changes described in this advisory, refer to: https://access.redhat.com/articles/11258 After installing the updated packages, the httpd daemon will be restarted automatically. Workaround: As a temporary workaround - HTTP/2 can be disabled by changing the configuration by removing h2 and h2c from the Protocols line(s) in the configuration file. The resulting line should read: Protocols http/1.1
