Re: invalid use of byte_test on sid:16603

Haha... Well I guess thanks for silently fixing this ;-).... Maybe you
should update the snort manual to reflect this eh?

Regards,

Will

case '<': idx->operator = BT_LESS_THAN;
break;

case '>': idx->operator = BT_GREATER_THAN;
break;

Is now...

            case '>': idx->operator = BT_GREATER_THAN;
                      cptr++;
                      if (*cptr == '=')
                          idx->operator = BT_GREATER_THAN_EQUAL;
                      else
                          cptr--;
                      break;

           case '<': idx->operator = BT_LESS_THAN;
                      cptr++;
                      if (*cptr == '=')
                          idx->operator = BT_LESS_THAN_EQUAL;
                      else
                          cptr--;
                      break;

Regards,

Will
