...which the current CVS version of tcpdump does:

        ulen = ntohs(up->uh_ulen);
        if (ulen < 8) {  
                (void)printf("%s > %s: truncated-udplength %d",
                             ipaddr_string(&ip->ip_src),
                             ipaddr_string(&ip->ip_dst),
                             ulen);
                return;
        }
