>
> When the TCP header length of input packets is invalid (i.e., less
> than 20 bytes or greater than 60 bytes), check_seq_option() will
> access illegal memory area when compare TCP Options, which may
> cause a segmentation fault.
>
> This patch adds missing invalid TCP header length check to avoid
> illegal memory accesses.
