Parse the value string into a buffer, don't copy/move stuff around. The buffer just needs to be 32767 bytes, e.g.:

unsigned char data[32767], *dataptr = data;
char *valptr = value + 1;

do
{
  while (isxdigit(valptr[0]) && isxdigit(valptr[1]))
  {
     // Decode hex digits and store in *dataptr;
     valptr += 2;
     dataptr ++;
     if (dataptr >= (data + sizeof(data))
       break;
  }

  if (*valptr == '>')
    break;
  else if (*valptr)
  {
    report_error(...);
    return (0);
  }

  if (!_ippFileReadToken(f, value, sizeof(value))
  {
    report_error(...);
    return (0);
  }

  valptr = value;
}

// data contains data, "dataptr - data" contains length

char value_concat[50000]; /* Concatenated string with hexadecimal values without whitespace */

while(value[strlen(value)-1] != '>')

If the syntax is:

"string"(language)

then we need to verify that the token we've read starts and ends with "(" and ")".

(*attr)->values[element].string.language = _cupsStrAlloc(value);

Use the same code for IPP_TAG_NAMELANG and IPP_TAG_TEXTLANG (with the two case statements together feeding into the same code).

(*attr)->values[element].string.text = _cupsStrAlloc(value);
if (!_ippFileReadToken(f, value, sizeof(value)))
{
report_error(f, v, user_data, "No Language Data in line %d of \"%s\".", f->linenum, f->filename);
return (0);
}
memmove(value, value+1, strlen(value));
value[strlen(value)-1]='\0'; /* Purge parenthesis */
