Descriptions

In FreeBSD before 11.2-RELEASE, a stack guard-page is available but is disabled by default. This results in the possibility a poorly written process could be cause a stack overflow.

En FreeBSD en versiones anteriores a la 11.2-RELEASE, una página guard de pila está disponible, pero está deshabilitada por defecto. Esto resulta en la posibilidad de que un proceso mal escrito provoque un desbordamiento de pila

Qualys has released a large amount of research surrounding the use of stack clash vulnerabilities and how stack guard on Linux can be bypassed.
