Tera que incluir no Admin controller:

protected function _isAllowed() {
        return Mage::getSingleton('admin/session')->isAllowed('catalog/seorewriter');
    }

Conforme o acl

<acl>
        <resources>
            <all>
                <title>Allow Everything</title>
            </all>
            <admin>
                <children>
                    <catalog>
                        <children>
                            <seorewriter>
                                <title>Url Filtros</title>
                                <sort_order>900</sort_order>
                            </seorewriter>
                        </children>
                    </catalog>
                </children>
            </admin>
        </resources>
    </acl>

@maxpchadwick criou um shell script que checa quais módulos usam o ACL e que precisaram ser
alterado por conta da atualização SUPEE-6285 

Basta pegar o arquivo abaixo Mpchadwick_Missing_Acl_Checker.php (Em ambiente de desenvolvimento)
e colocar ele dentro da pasta shel do magento e executar o comando: php Mpchadwick_Missing_Acl_Checker.php

Ele irá criar um CSV contendo os módulos que precisam ser alterado. Exemplo da saída do CSV:
