Descriptions

In FreeBSD 12.1-STABLE before r362281, 11.4-STABLE before r362281, and 11.4-RELEASE before p1, long values in the user-controlled PATH environment variable cause posix_spawnp to write beyond the end of the heap allocated stack possibly leading to arbitrary code execution.

En FreeBSD versiones 12.1-STABLE anteriores a r362281, versiones 11.4-STABLE anteriores a r362281 y versiones 11.4-RELEASE anteriores a p1, los valores largos en la variable de entorno PATH controlada por el usuario causan que la función posix_spawnp escriba más allá del final de la región stack asignada a la región heap de la memoria, conllevando posiblemente a una ejecución de código arbitrario
