1c668136af Parse HelloVerifyRequest buffer overread: add changelog entry 2019-09-27 14:08:12 +02:00

b64bf0638f Parse HelloVerifyRequest: avoid buffer overread at the start
In ssl_parse_hello_verify_request, we read 3 bytes (version and cookie
length) without checking that there are that many bytes left in
ssl->in_msg. This could potentially read from memory outside of the
ssl->receive buffer (which would be a remotely exploitable
crash).

b51130dd5c Parse HelloVerifyRequest: avoid buffer overread on the cookie
In ssl_parse_hello_verify_request, we print cookie_len bytes without
checking that there are that many bytes left in ssl->in_msg. This
could potentially log data outside the received message (not a big
deal) and could potentially read from memory outside of the receive
buffer (which would be a remotely exploitable crash).

a9478bab08 Fix configuration short name in key-exchanges.pl

a matter of Perl coding style.

178c9aa966 Key derivation: forbid output_key without input_key
If none of the inputs to a key derivation is a
PSA_KEY_DERIVATION_INPUT_SECRET passed with
psa_key_derivation_input_key(), forbid
psa_key_derivation_output_key(). It usually doesn't make sense to
derive a key object if the secret isn't itself a proper key.

1a2904c49a derive_input test function: Try output afterwards
After passing some inputs, try getting one byte of output, just to
check that this succeeds (for a valid sequence of inputs) or fails
with BAD_STATE (for an invalid sequence of inputs). Either output a
1-byte key or a 1-byte buffer depending on the test data.

The test data was expanded as follows:
* Output key type (or not a key): same as the SECRET input if success
  is expected, otherwise NONE.
* Expected status: PSA_SUCCESS after valid inputs, BAD_STATE after any
  invalid input.

224b0d656a Key derivation: allow both keys and direct inputs
Allow a direct input as the SECRET input step in a key derivation, in
addition to allowing DERIVE keys. This makes it easier for
applications to run a key derivation where the "secret" input is
obtained from somewhere else. This makes it possible for the "secret"
input to be empty (keys cannot be empty), which some protocols do (for
example the IV derivation in EAP-TLS).

Conversely, allow a RAW_DATA key as the INFO/LABEL/SALT/SEED input to a key
derivation, in addition to allowing direct inputs. This doesn't
improve security, but removes a step when a personalization parameter
is stored in the key store, and allows this personalization parameter
to remain opaque.

Add test cases that explore step/key-type-and-keyhood combinations.

6842ba4d7a PSA crypto KDF: test bytes/key input independently of the step type
This commit only makes derive_input more flexible so that the key
derivation API can be tested with different key types and raw data for
each input step. The behavior of the test cases remains the same.

31b0a3c351 Add a test component with malloc(0) returning NULL
Exercise the library functions with calloc returning NULL for a size
of 0. Make this a separate job with UBSan (and ASan) to detect
places where we try to dereference the result of calloc(0) or to do
things like

    buf = calloc(size, 1);
    if (buf == NULL && size != 0) return INSUFFICIENT_MEMORY;
    memcpy(buf, source, size);

which has undefined behavior when buf is NULL at the memcpy call even
if size is 0.

This is needed because other test components jobs either use the system
malloc which returns non-NULL on Linux and FreeBSD, or the
memory_buffer_alloc malloc which returns NULL but does not give as
useful feedback with ASan (because the whole heap is a single C
object).

af7724e985 Fix endianity issue when reading uint32
The uint32 is given as a bigendian stream, in the tests, however,
the char buffer that collected the stream read it as is,
without converting it. Add a temporary buffer, to call `greentea_getc()`
8 times, and then put it in the correct endianity for input to `unhexify()`.
