The libcurl API function called `curl_maprintf()` before version 7.51.0 can be tricked into doing a double-free due to an unsafe `size_t` multiplication, on systems using 32 bit `size_t` variables.
La función API de libcurl llamada "curl_maprintf()" en versiones anteriores a la 7.51.0 puede ser engañada para realizar una doble liberación (double free) debido a una multiplicación "size_t" insegura en sistemas que utilizan variables "size_t" de 32 bits.
