Descriptions

musl libc before 1.1.17 has a buffer overflow via crafted DNS replies because dns_parse_callback in network/lookup_name.c does not restrict the number of addresses, and thus an attacker can provide an unexpected number by sending A records in a reply to an AAAA query.

musl libc, en versiones anteriores a la 1.1.17, tiene un desbordamiento de búfer mediante respuestas DNS manipuladas, debido a que dns_parse_callback en network/lookup_name.c no restringe el número de direcciones y, por lo tanto, un atacante puede proporcionar un número inesperado enviando registros A en una respuesta a una consulta AAAA.
