1. File affected:       owfile.c
   Procedure affected:  int owReadFile(int portnum, uchar *filename, 
                                       uchar *buf)
   Error description:

        (line 121)
      pglen = owReadPacketStd(portnum,TRUE,filepg,pgbuf);  

      // check result of read
      if (pglen <= 0)
         return READ_ERROR;
 
   But pglen is declared as an unsigned char and will never be less
   than 0. Therefore is owReadPacketStd returns an error (-1), pglen 
   has a value of 0xFF and the error is not caught.  Consequently, 
   if the size of the buffer passed in pointer buf < 255, this will 
   create a difficult to find, buffer overflow. This would be common 
   as the maximum size expected from a  owReadPacketStd is 29 Bytes.
 
   Fix:  Make pglen a signed value (int).

2. File affected:      owfile.c
   Procedure affected: int owFormatWriteFile(uchar *filename, 
                                             int fllen, uchar *buf)
   Error description:

   When the function is updating the bitmap for the DS1996 
   (type 0x0c) iButton, the bitmap image is incorrectly created if 
   the file is larger than 220 pages.
 
   Fix:  The line (221)  
             if (i <= 221) 
         should read 
             if (i < 221)

   The last partial secret, in this case the only partial secret

   Fix: Write over the page at the end of the secret insertion.
