CVE-2015-9253

Priority
Description
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.
Notes
