CVE-2017-11144

En PHP, en versiones anteriores a la 5.6.31, las versiones 7.x anteriores a la 7.0.21 y las versiones 7.1.x anteriores a la 7.1.7, el código de sellado PEM de la extensión openssl no comprobó el valor de retorno de la función de sellado de OpenSSL, lo que podría conducir al cierre inesperado del intérprete de PHP. Esto está relacionado con un conflicto de interpretación para un número negativo en ext/openssl/openssl.c y una omisión de documentación OpenSSL.
