In FreeBSD 12.2-STABLE before r367402, 11.4-STABLE before r368202, 12.2-RELEASE before p1, 12.1-RELEASE before p11 and 11.4-RELEASE before p5 the handler for a routing option caches a pointer into the packet buffer holding the ICMPv6 message. However, when processing subsequent options the packet buffer may be freed, rendering the cached pointer invalid. The network stack may later dereference the pointer, potentially triggering a use-after-free. En FreeBSD versiones 12.2-STABLE anteriores a r367402, versiones 11.4-STABLE anteriores a r368202, versiones 12.2-RELEASE anteriores a p1, versiones 12.1-RELEASE anteriores a p11 y versiones 11.4-RELEASE anteriores a p5, el manejador para una opción de enrutamiento almacena en caché un puntero en el búfer de paquetes que contiene el mensaje ICMPv6. Sin embargo, cuando se procesan opciones posteriores, el búfer de paquetes puede ser liberado, renderizando el puntero inválido en caché. • https://security.FreeBSD.org/advisories/FreeBSD-SA-20:31.icmp6.asc https://security.netapp.com/advisory/ntap-20210720-0001 • CWE-416: Use After Free •
