https://github.com/openssl/openssl/commits/ and pick the appropriate
release branch.
Changes between 1.1.1c and 1.1.1d [10 Sep 2019]
*) Fixed a fork protection issue. OpenSSL 1.1.1 introduced a rewritten random
number generator (RNG). This was intended to include protection in the
event of a fork() system call in order to ensure that the parent and child
processes did not share the same RNG state. However this protection was not
being used in the default case.
A partial mitigation for this issue is that the output from a high
precision timer is mixed into the RNG state so the likelihood of a parent
and child process sharing state is significantly reduced.
If an application already calls OPENSSL_init_crypto() explicitly using
OPENSSL_INIT_ATFORK then this problem does not occur at all.
(CVE-2019-1549)
[Matthias St. Pierre]
*) For built-in EC curves, ensure an EC_GROUP built from the curve name is
used even when parsing explicit parameters, when loading a serialized key
or calling `EC_GROUP_new_from_ecpkparameters()`/
`EC_GROUP_new_from_ecparameters()`.
This prevents bypass of security hardening and performance gains,
especially for curves with specialized EC_METHODs.
By default, if a key encoded with explicit parameters is loaded and later
serialized, the output is still encoded with explicit parameters, even if
internally a "named" EC_GROUP is used for computation.
[Nicola Tuveri]
*) Compute ECC cofactors if not provided during EC_GROUP construction. Before
this change, EC_GROUP_set_generator would accept order and/or cofactor as
NULL. After this change, only the cofactor parameter can be NULL. It also
does some minimal sanity checks on the passed order.
(CVE-2019-1547)
[Billy Bob Brumley]
*) Fixed a padding oracle in PKCS7_dataDecode and CMS_decrypt_set1_pkey.
An attack is simple, if the first CMS_recipientInfo is valid but the
second CMS_recipientInfo is chosen ciphertext. If the second
recipientInfo decodes to PKCS #1 v1.5 form plaintext, the correct
encryption key will be replaced by garbage, and the message cannot be
decoded, but if the RSA decryption fails, the correct encryption key is
used and the recipient will not notice the attack.
As a work around for this potential attack the length of the decrypted
key must be equal to the cipher default key length, in case the
certifiate is not given and all recipientInfo are tried out.
The old behaviour can be re-enabled in the CMS code by setting the
CMS_DEBUG_DECRYPT flag.
(CVE-2019-1563)
[Bernd Edlinger]
*) Early start up entropy quality from the DEVRANDOM seed source has been
improved for older Linux systems. The RAND subsystem will wait for
/dev/random to be producing output before seeding from /dev/urandom.
The seeded state is stored for future library initialisations using
a system global shared memory segment. The shared memory identifier
can be configured by defining OPENSSL_RAND_SEED_DEVRANDOM_SHM_ID to
the desired value. The default identifier is 114.
[Paul Dale]
*) Correct the extended master secret constant on EBCDIC systems. Without this
fix TLS connections between an EBCDIC system and a non-EBCDIC system that
negotiate EMS will fail. Unfortunately this also means that TLS connections
between EBCDIC systems with this fix, and EBCDIC systems without this
fix will fail if they negotiate EMS.
[Matt Caswell]
*) Use Windows installation paths in the mingw builds
Mingw isn't a POSIX environment per se, which means that Windows
paths should be used for installation.
(CVE-2019-1552)
[Richard Levitte]
*) Changed DH_check to accept parameters with order q and 2q subgroups.
With order 2q subgroups the bit 0 of the private key is not secret
but DH_generate_key works around that by clearing bit 0 of the
private key for those. This avoids leaking bit 0 of the private key.
[Bernd Edlinger]
*) Significantly reduce secure memory usage by the randomness pools.
[Paul Dale]
*) Revert the DEVRANDOM_WAIT feature for Linux systems
The DEVRANDOM_WAIT feature added a select() call to wait for the
/dev/random device to become readable before reading from the
/dev/urandom device.
It turned out that this change had negative side effects on
performance which were not acceptable. After some discussion it
was decided to revert this feature and leave it up to the OS
resp. the platform maintainer to ensure a proper initialization
during early boot time.

(CVE-2019-1543)
[Matt Caswell]
*) Add DEVRANDOM_WAIT feature for Linux systems
On older Linux systems where the getrandom() system call is not available,
OpenSSL normally uses the /dev/urandom device for seeding its CSPRNG.
Contrary to getrandom(), the /dev/urandom device will not block during
early boot when the kernel CSPRNG has not been seeded yet.
To mitigate this known weakness, use select() to wait for /dev/random to
become readable before reading from /dev/urandom.
*) Ensure that SM2 only uses SM3 as digest algorithm

#
# Add support for hardware AES192/256 and reschedule instructions to
# minimize/avoid Address Generation Interlock hazard and to favour
# dual-issue z10 pipeline. This gave ~25% improvement on z10 and
# almost 50% on z9. The gain is smaller on z10, because being dual-
# issue z10 makes it impossible to eliminate the interlock condition:
# critial path is not long enough. Yet it spends ~24 cycles per byte
# critical path is not long enough. Yet it spends ~24 cycles per byte
# processed with 128-bit key.
#
# Unlike previous version hardware support detection takes place only

* In the following we assume that g is not 0, 1 or p-1, since it
* would generate only trivial subgroups.
* For this case, g is a generator of the order-q subgroup if
* g^q mod p == 1.
* Or in terms of the Legendre symbol: (g/p) == 1.
*
* Having said all that,
* there is another special case method for the generators 2, 3 and 5.
* Using the quadratic reciprocity law it is possible to solve

* for 3, p mod 12 == 5 <<<<< does not work for safe primes.
* for 5, p mod 10 == 3 or 7
*
* Thanks to Phil Karn for the pointers about the
* special generators and for answering some of my questions.
*
* I've implemented the second simple method :-).
* Since DH should be using a safe prime (both p and q are prime),
* this generator function can take a very very long time to run.
