Descriptions
In FreeBSD 11.3-PRERELEASE and 12.0-STABLE before r347591, 11.2-RELEASE before 11.2-RELEASE-p10, and 12.0-RELEASE before 12.0-RELEASE-p4, a bug in the pf IPv6 fragment reassembly logic incorrectly uses the last extension header offset from the last received packet instead of the first packet allowing maliciously crafted IPv6 packets to cause a crash or potentially bypass the packet filter.
En FreeBSD 11.3-PRERELEASE y 12.0-STABLE anterior a r347591, 11.2-RELEASE anterior a 11.2-RELEASE-p10, y 12.0-RELEASE antes de 12.0-RELEASE-p4, un error en la lógica de reensamblado del fragmento pf IPv6 usa incorrectamente la última extensión del encabezado desde el desvío el último paquete recibido en vez del primer paquete permitiendo que los paquetes IPv6 diseñados con fines maliciosos originen un bloqueo o omitan potencialmente el Packet Filter.
