https://github.com/openssl/openssl/commits/ and pick the appropriate
release branch.
Changes between 1.1.1b and 1.1.1c [28 May 2019]
*) Add build tests for C++. These are generated files that only do one
thing, to include one public OpenSSL head file each. This tests that
the public header files can be usefully included in a C++ application.
This test isn't enabled by default. It can be enabled with the option
'enable-buildtest-c++'.
[Richard Levitte]
*) Enable SHA3 pre-hashing for ECDSA and DSA.
[Patrick Steuer]
*) Change the default RSA, DSA and DH size to 2048 bit instead of 1024.
This changes the size when using the genpkey app when no size is given. It
fixes an omission in earlier changes that changed all RSA, DSA and DH
generation apps to use 2048 bits by default.
[Kurt Roeckx]
*) Reorganize the manual pages to consistently have RETURN VALUES,
EXAMPLES, SEE ALSO and HISTORY come in that order, and adjust
util/fix-doc-nits accordingly.
[Paul Yang, Joshua Lock]
*) Add the missing accessor EVP_PKEY_get0_engine()
[Matt Caswell]
*) Have apps like 's_client' and 's_server' output the signature scheme
along with other cipher suite parameters when debugging.
[Lorinczy Zsigmond]
*) Make OPENSSL_config() error agnostic again.
[Richard Levitte]
*) Do the error handling in RSA decryption constant time.
[Bernd Edlinger]
*) Prevent over long nonces in ChaCha20-Poly1305.
ChaCha20-Poly1305 is an AEAD cipher, and requires a unique nonce input
for every encryption operation. RFC 7539 specifies that the nonce value
(IV) should be 96 bits (12 bytes). OpenSSL allows a variable nonce length
and front pads the nonce with 0 bytes if it is less than 12
bytes. However it also incorrectly allows a nonce to be set of up to 16
bytes. In this case only the last 12 bytes are significant and any
additional leading bytes are ignored.
It is a requirement of using this cipher that nonce values are
unique. Messages encrypted using a reused nonce value are susceptible to
serious confidentiality and integrity attacks. If an application changes
the default nonce length to be longer than 12 bytes and then makes a
change to the leading bytes of the nonce expecting the new value to be a
new unique nonce then such an application could inadvertently encrypt
messages with a reused nonce.
Additionally the ignored bytes in a long nonce are not covered by the
integrity guarantee of this cipher. Any application that relies on the
integrity of these ignored leading bytes of a long nonce may be further
affected. Any OpenSSL internal use of this cipher, including in SSL/TLS,
is safe because no such use sets such a long nonce value. However user
applications that use this cipher directly and set a non-default nonce
length to be longer than 12 bytes may be vulnerable.
This issue was reported to OpenSSL on 16th of March 2019 by Joran Dirk
Greef of Ronomon.
(CVE-2019-1543)
[Matt Caswell]
*) Ensure that SM2 only uses SM3 as digest algorithm

Typically OpenSSL will automatically load a system config

enable-buildtest-c++
While testing, generate C++ buildtest files that
simply check that the public OpenSSL header files
are usable standalone with C++.
Enabling this option demands extra care. For any
compiler flag given directly as configuration
option, you must ensure that it's valid for both
the C and the C++ compiler. If not, the C++ build
test will most likely break. As an alternative,
you can use the language specific variables, CFLAGS
and CXXFLAGS.

Calling BIO_set_mem_buf() on a BIO created with BIO_new_secmem() will
give undefined results, including perhaps a program crash.
Switching the memory BIO from read write to read only is not supported and
can give undefined results including a program crash. There are two notable
exceptions to the rule. The first one is to assign a static memory buffer
immediately after BIO creation and set the BIO as read only.
The other supported sequence is to start with read write BIO then temporarily
switch it to read only and call BIO_reset() on the read only BIO immediately
before switching it back to read write. Before the BIO is freed it must be
switched back to the read write mode.
Calling BIO_get_mem_ptr() on read only BIO will return a BUF_MEM that
contains only the remaining data to be read. If the close status of the
BIO is set to BIO_NOCLOSE, before freeing the BUF_MEM the data pointer
in it must be set to NULL as the data pointer does not point to an
allocated memory.
