Manuel Pégourié-Gonnard 58fb49531d Fix potential buffer overflow in mpi_read_string()
Found by Guido Vranken.

Two possible integer overflows (during << 2 or addition in BITS_TO_LIMB())
could result in far too few memory to be allocated, then overflowing the
buffer in the subsequent for loop.

Both integer overflows happen when slen is close to or greater than
SIZE_T_MAX >> 2 (ie 2^30 on a 32 bit system).

Note: one could also avoid those overflows by changing BITS_TO_LIMB(s << 2) to
CHARS_TO_LIMB(s >> 1) but the solution implemented looks more robust with
respect to future code changes.

Manuel Pégourié-Gonnard f7022d1131 Fix bug in server parsing point formats extension
There is only one length byte but for some reason we skipped two, resulting in
reading one byte past the end of the extension. Fortunately, even if that
extension is at the very end of the ClientHello, it can't be at the end of the
buffer since the ClientHello length is at most SSL_MAX_CONTENT_LEN and the
buffer has some more room after that for MAC and so on. So there is no
buffer overread.

Possible consequences are:
- nothing, if the next byte is 0x00, which is a comment first byte for other
  extensions, which is why the bug remained unnoticed
- using a point format that was not offered by the peer if next byte is 0x01.
  In that case the peer will reject our ServerKeyExchange message and the
handshake will fail.
- thinking that we don't have a common point format even if we do, which will
  cause us to immediately abort the handshake.
None of these are a security issue.

The same bug was fixed client-side in fd35af15
2015-09-16 11:32:18 +02:00
Manuel Pégourié-Gonnard ea5370d4a2 Don't allow reconnect during handshake
Especially for resumed handshake, it's entirely possible for an epoch=0
ClientHello to be retransmitted or arrive so late that the server is already
at epoch=1. There is no good way to detect whether it's that or a reconnect.

However:
- a late ClientHello seems more likely that client going down and then up
  again in the middle of a handshake
- even if that's the case, we'll time out on that handshake soon enough
- we don't want to break handshake flows that used to work
So the safest option is to not treat that as a reconnect.

Manuel Pégourié-Gonnard ddfe5d20d1 Tune dependencies
Don't depend on srv.c in config.h, but add explicit checks. This is more
in line with other options that only make sense server-side, and also it
allows to test full config minus srv.c more easily.

also depend on SRV_C as is doesn't make sense on client.

Manuel Pégourié-Gonnard fdbdd72b8b Skip to trusted certs early in the chain
This helps in the case where an intermediate certificate is directly trusted.
In that case we want to ignore what comes after it in the chain, not only for
performance but also to avoid false negatives (eg an old root being no longer
trusted while the newer intermediate is directly trusted).

auth error in any other way, so it is probably the right thing to do.

Assume we have two trusted CAs with the same name, the first uses ECDSA 256

check before we checked the key types match, we'll raise the badkey flags when
checking the EC-256 CA and it will remain up even when we finally find the
correct CA. So, move the check for the key size after signature verification,
which implicitly checks the key type.

Manuel Pégourié-Gonnard 1cd10adc7c Update prototype of x509write_set_key_usage()
Allow for future support of decipherOnly and encipherOnly. Some work will be
required to ensure we still write only one byte when only one is needed.

Manuel Pégourié-Gonnard 7320eb46d4 Remove references to some Montgomery curves
After all it looks like those won't become standard.
2015-06-23 13:09:10 +02:00
Manuel Pégourié-Gonnard 9386664543 Move from inttypes.h to stdint.h
Some toolchains do not have inttypes.h, and we only need stdint.h which is a
subset of it.

Manuel Pégourié-Gonnard e7e89844d6 Fix and document corner-cases of time checking 2015-06-22 23:41:24 +02:00
Manuel Pégourié-Gonnard 57e10d71be Fix potential NULL dereference.
Introduced when moving from gmtime_r() to gmtime().
Found with fbinfer.

Manuel Pégourié-Gonnard f9b85d96a9 Fix potential resource leak in X.509 parse dir
Found with fbinfer.

Manuel Pégourié-Gonnard bcf13bab5d Fix issue with MemSan and entropy
Due to the recent change about entropy sources strength, it is no longer
acceptable to just disable the platform source. So, instead "fix" it so that
it is clear to MemSan that memory is initialized.

I tried __attribute__((no_sanitize_memory)) and MemSan's blacklist file, but
couldn't seem to get them to work.

Manuel Pégourié-Gonnard cdc26ae099 Add mbedtls_ssl_set_hs_authmode
While at it, fix the following:
- on server with RSA_PSK, we don't want to set flags (client auth happens via
  the PSK, no cert is expected).
- use safer tests (eg == OPTIONAL vs != REQUIRED)

Manuel Pégourié-Gonnard 9dbaf400ef Rationalize other snprintf() uses 2015-06-22 14:42:04 +02:00
Manuel Pégourié-Gonnard 1685368408 Rationalize snprintf() usage in X.509 modules 2015-06-22 14:42:04 +02:00
Manuel Pégourié-Gonnard 6c0c8e0d3d Include fixed snprintf for Windows in platform.c
Use _WIN32 to detect it rather that _MSC_VER as it turns out MSYS2 uses the
broken MS version by default too.

Manuel Pégourié-Gonnard f9cbd73191 Update generated files 2015-06-22 14:40:56 +02:00
Manuel Pégourié-Gonnard 7580ba475d Add a concept of entropy source strength.
The main goal is, we want and error if cycle counter is the only source.
2015-06-22 14:40:56 +02:00
Manuel Pégourié-Gonnard 3f77dfbd52 Add MBEDTLS_ENTROPY_HARDWARE_ALT
Makes it easier for an external module to plug its hardware entropy collector.

Manuel Pégourié-Gonnard 60c793bdc9 Split HAVE_TIME into HAVE_TIME + HAVE_TIME_DATE
First one means we have time() but it may not return the actual wall clock
time, second means it does.

Clarify a few comments too.
2015-06-18 14:58:58 +02:00
Manuel Pégourié-Gonnard b31c5f68b1 Add SSL presets.
No need to use a separate profile as in X.509, everything we need is already
in ssl_config. Just load appropriate values.
2015-06-17 14:59:27 +02:00
Manuel Pégourié-Gonnard 7bfc122703 Implement sig_hashes 2015-06-17 14:34:48 +02:00
Manuel Pégourié-Gonnard 36a8b575a9 Create API for mbedtls_ssl_conf_sig_hashes().
Not implemented yet.

Manuel Pégourié-Gonnard 9d412d872c Small internal changes in curve checking
- switch from is_acceptable to the more usual check
- add NULL check just in case user screwed up config
2015-06-17 14:27:39 +02:00
Manuel Pégourié-Gonnard a83e4e2bf5 Extra check in verify_with_profile()
This could happen if someone doesn't set the SSL configuration properly. In
that case we don't want to segfault...
2015-06-17 14:27:38 +02:00
Manuel Pégourié-Gonnard b541da6ef3 Fix define for ssl_conf_curves()
This is a security feature, it shouldn't be optional.

Manuel Pégourié-Gonnard cbb1f6e5cb Implement cert profile checking 2015-06-17 14:27:38 +02:00
Manuel Pégourié-Gonnard f8ea856296 Change data structure of profiles to bitfields
- allows to express 'none' or 'all' more easily than lists
- more compact and easier to declare statically
- easier to check too

Only drawback: if we ever have more than 32 curves, we'll need an ABI change to
make that field a uint64_t.
