Descriptions
An issue was discovered in PHP 7.3.x before 7.3.0alpha3, 7.2.x before 7.2.8, and before 7.1.20. The php-fpm master process restarts a child process in an endless loop when using program execution functions (e.g., passthru, exec, shell_exec, or system) with a non-blocking STDIN stream, causing this master process to consume 100% of the CPU, and consume disk space with a large volume of error logs, as demonstrated by an attack by a customer of a shared-hosting facility.
Se ha descubierto un problema en PHP en versiones 7.3.x anteriores a la 7.3.0alpha3, versiones 7.2.x anteriores a la 7.2.8 y anteriores a la 7.1.20. El proceso maestro php-fpm reinicia un proceso hijo en un bucle infinito cuando se utilizan funciones de ejecución de programas (por ejemplo, passthru, exec, shell_exec o system) con un flujo non-blocking-STDIN y consumir el espacio del disco con un gran volumen de logs de error, tal y como queda demostrado con un ataque a un cliente de una instalación de alojamiento compartido.
