✅ Remediation

For details on how to apply this update, which includes the changes described in this advisory, refer to: https://images.redhat.com/ Workaround: If dynamic mass virtual hosting is not required, disable the `mod_vhost_alias` module: 1. Comment out the `vhost_alias_module` line in `/etc/httpd/conf.modules.d/00-base.conf` (or the respective configuration file loading the module): ``` # LoadModule vhost_alias_module modules/mod_vhost_alias.so ``` 2. Restart the Apache HTTP Server service to apply the change: ``` systemctl restart httpd ``` Warning: Restarting or reloading the `httpd` service interrupts active connections. Disabling `mod_vhost_alias` will break virtual host resolution for deployments configured with directives such as `VirtualDocumentRoot` or `VirtualScriptAlias`. Workaround: See the security bulletin for a detailed mitigation procedure.
