Changes between 1.1.1c and 1.1.1d [xx XXX xxxx]
+ *) 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]
+
+ *) Fixed a padding oracle in PKCS7_decrypt() and CMS_decrypt(). In situations
+ where an attacker receives automated notification of the success or failure
+ of a decryption attempt an attacker, after sending a very large number of
+ messages to be decrypted, can recover a CMS/PKCS7 transported encryption
+ key or decrypt any RSA encrypted message that was encrypted with the public
+ RSA key, using a Bleichenbacher padding oracle attack. Applications are not
+ affected if they use a certificate together with the private RSA key to the
+ CMS_decrypt or PKCS7_decrypt functions to select the correct recipient info
+ to decrypt.
+ (CVE-2019-1563)

*) 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()`/
