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) [Bernd Edlinger] *) 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()`/ Loading Loading @@ -70,6 +97,7 @@ 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.
