Descriptions

In FreeBSD 11.3-PRERELEASE before r345378, 12.0-STABLE before r345377, 11.2-RELEASE before 11.2-RELEASE-p10, and 12.0-RELEASE before 12.0-RELEASE-p4, a bug in pf does not check if the outer ICMP or ICMP6 packet has the same destination IP as the source IP of the inner protocol packet allowing a maliciously crafted ICMP/ICMP6 packet could bypass the packet filter rules and be passed to a host that would otherwise be unavailable.

n FreeBSD 11.3-PRERELEASE antes de r345378, 12.0-ESTABLE antes de r345377, 11.2-RELEASE antes de 11.2-RELEASE-p10, y 12.0-RELEASE antes de 12.0-RELEASE-p4, un error en pf no verifica si el paquete ICMP exterior o ICMP6 tiene la misma IP de destino que la IP de la fuente del paquete de protocolo interno permitiendo la creación maliciosa de un paquete ICMP / ICMP6 podría eludir las reglas de el Packet Filter y pasar a un host que de lo contrario estará inhabilitado.
