$wpdb->escape warning in domain_mapping.php

The known bug for the older sunrise.php is also in domain_mapping.php

Line 341
$domain = $wpdb->escape( $_POST[ 'domain' ] );

Line 374
$domain = $wpdb->escape( $_GET[ 'domain' ] );

Line 519
$domain = $wpdb->get_var( "SELECT domain FROM {$wpdb->dmtable} WHERE blog_id = '{$wpdb->blogid}' AND domain = '" . $wpdb->escape( $_SERVER[ 'HTTP_HOST' ] ) . "' LIMIT 1" );

A fix would be great!
