Descriptions

In PHP through 5.6.33, 7.0.x before 7.0.28, 7.1.x through 7.1.14, and 7.2.x through 7.2.2, there is a stack-based buffer under-read while parsing an HTTP response in the php_stream_url_wrap_http_ex function in ext/standard/http_fopen_wrapper.c. This subsequently results in copying a large string.

En PHP hasta la versión 5.6.33, versiones 7.0.x anteriores a la 7.0.28, versiones 7.1.x hasta la 7.1.14 y versiones 7.2.x hasta la 7.2.2, hay una sublectura de búfer basada en pila al analizar una respuesta HTTP en la función php_stream_url_wrap_http_ex en ext/standard/http_fopen_wrapper.c. Esto resulta en la copia de una cadena larga.

PHP version 7.2.2 contains a memory corruption bug while parsing malformed HTTP response packets.
