6251836753 Add unit tests for X509 certificate date parsing 2017-02-28 12:05:44 +00:00

97871b2486 Merge branch 'iotssl-1071-ca-flags'
Fixes a regression introduced by an earlier commit that modified
x509_crt_verify_top() to ensure that valid certificates that are after past or
future valid in the chain are processed. However the change introduced a change
in behaviour that caused the verification flags MBEDTLS_X509_BADCERT_EXPIRED and
MBEDTLS_BADCERT_FUTURE to always be set whenever there is a failure in the
verification regardless of the cause.

The fix maintains both behaviours:

 * Ensure that valid certificates after future and past are verified
 * Ensure that the correct verification flags are set.

dce1016624 Merge branch 'iotssl-1077-dos-crl'
Modifies the function mbedtls_x509_crl_parse() to ensure that a CRL in PEM
format with trailing characters after the footer does not result in the
execution of an infinite loop.

53695beeda Merge branch 'iotssl-1155-hashlen-type'
Introduces additional checks in the PK module for 64-bit systems only. The
problem is that the API functions in the PK abstraction accept a size_t value
for the hashlen, while the RSA module accepts an unsigned int for the hashlen.
Instead of silently casting size_t to unsigned int, this change checks whether
the hashlen overflows an unsigned int and returns an error.

6a54336897 Fix integer overflows in buffer bound checks
Fix potential integer overflows in the following functions:
  * mbedtls_md2_update() to be bypassed and cause
  * mbedtls_cipher_update()
  * mbedtls_ctr_drbg_reseed()
This overflows would mainly be exploitable in 32-bit systems and could
cause buffer bound checks to be bypassed.

9f430c15d8 Add tests for out flags from x509_crt_verify_top()
The tests load certificate chains from files. The CA chains contain a
past or future certificate and an invalid certificate. The test then
checks that the flags set are MBEDTLS_X509_BADCERT_EXPIRED or
MBEDTLS_X509_BADCERT_FUTURE.

e5dc202469 Restore P>Q in RSA key generation (#558)
The PKCS#1 standard says nothing about the relation between P and Q
but many libraries guarantee P>Q and mbed TLS did so too in earlier
versions.

This commit restores this behaviour.

Fixes the test suites to consistently use mbedtls_fprintf to output to

Also redirects output from the tests to /dev/null to avoid confusing
output if the test suite code or library outputs anything to stdout.
