Descriptions

A bug exists in the way mod_ssl handled client renegotiations. A remote attacker could send a carefully crafted request that would cause mod_ssl to enter a loop leading to a denial of service. This bug can be only triggered with Apache HTTP Server version 2.4.37 when using OpenSSL version 1.1.1 or later, due to an interaction in changes to handling of renegotiation attempts.

Existe un problema en la manera en la que mod_ssl gestionaba registros de cliente. Un atacante remoto podría enviar una petición especialmente manipulada que conduciría a que mod_ssl entre en un bucle, provocando una denegación de servicio (DoS). Este problema puede desencadenarse con Apache HTTP Server, en su versión 2.4.37, a la hora de utilizar OpenSSL, en versiones 1.1.1 o anteriores, debido a una interacción en cambios de la gestión de intentos de renegociación.
