Too long list of installed applets causes IllegalStateException: Length is out of the range (older gppro v0.3.4 works) #327

Closed petrs closed 11 months ago

petrs commented 1 year ago

Describe the bug

The list of installed applets is not displayed in current version of gppro while is correctly displayed in gppro v0.3.4. If some applets are uninstalled (via gppro v0.3.4), --list start to work again.

Additional context

Add any other context about the problem here.

martinpaljak commented 1 year ago

Do you have a comparable log with a working version?

The last line is the culprit. According to the specification, 0x6310 should be returned if there is more data to return with GET STATUS than fits into current APDU. This is a full 256 byte return APDU, it is apparently truncated, but the status word from the chip does not indicate "more data available". Looking at the code of v0.3.4 that should fail the same way. maybe issuing additional GET STATUS to the chip actually returns the additional portion (even if it is not indicated by the chip) and a workaround is possible ("if parsing fails with incomplete data, try to read more 1..N times").

martinpaljak commented 1 year ago

OK. What you are possibly observing (older version working for delete and newer not) is that later versions try to read the registry before issuing a DELETE command, to check if things are there and/or to give helpful recommendations. That will indeed fail with later versions, as the registry is tried to be constructed and that fails with an exception and you can't even delete. The culprit here is still a broken chip that does not indicate additional data when the returned data buffer is too large (too many applets installed). Thing to improve here would be make sure that "-f" would blindly issue a delete command, as not to "lock you out"

petrs commented 1 year ago

Thank you for dissecting the issue. I did not tried to do delete command initially, just the --list . Only when I used older version, I was able to finish list and got AIDs to delete. But I agree that the culprit is likely what you described. I will try to get card back into the same state with too many applets to fit into single GET DATA apdu and provide logs again

petrs commented 11 months ago

I tried to hard reproduce it again with clean Taysis SIMoME card(s) ICFabricationDate=6194 (2016-07-12) by continually uploading enough applets to overflow the response in 84F21002 command. As response to 84F21002 grows but below 256B, it is returning SW 9000 as expected. Then as it was bigger than 256B, I got SW 6310 (again as expected). Subsequent 84F21003 then returns remaining data - again, as expected. (see the log below).

I now believe that either the problem was on some older Taysis SIMoME card with slightly different behavior than the cards I test on now, or caused by non-deterministic behavior as a result of us testing with many different applets - just overflow >256B of the 84F21002 response is not enough to cause it.

Feel free to close this issue as unreproducible. Thank you again for looking into it.

OK, thx, closing as not repeatable...
