FreeBSD : FreeBSD -- ipsec crash or denial of service (c0c5afef-38db-11e8-8b7f-a4badb2f469b)

The length field of the option header does not count the size of the option header itself. This causes a problem when the length is zero, the count is then incremented by zero, which causes an infinite loop. In addition there are pointer/offset mistakes in the handling of IPv4 options. Impact : A...
