OpenSSL 1.1.1

-### Changes between 1.1.1i and 1.1.1j [xx XXX xxxx]

- * Fixed SRP_Calc_client_key so that it uses constant time. The previous
+### Changes between 1.1.1i and 1.1.1j [16 Feb 2021]
+
+ * Fixed the X509_issuer_and_serial_hash() function. It attempts to
+ create a unique hash value based on the issuer and serial number data
+ contained within an X509 certificate. However it was failing to correctly
+ handle any errors that may occur while parsing the issuer field (which might
+ occur if the issuer field is maliciously constructed). This may subsequently
+ result in a NULL pointer deref and a crash leading to a potential denial of
+ service attack.
+ ([CVE-2021-23841])
+
+ *Matt Caswell*
+
+ * Fixed the RSA_padding_check_SSLv23() function and the RSA_SSLV23_PADDING
+ padding mode to correctly check for rollback attacks. This is considered a
+ bug in OpenSSL 1.1.1 because it does not support SSLv2. In 1.0.2 this is
+ CVE-2021-23839.
+
+ *Matt Caswell*
+
+ Fixed the EVP_CipherUpdate, EVP_EncryptUpdate and EVP_DecryptUpdate
+ functions. Previously they could overflow the output length argument in some
+ cases where the input length is close to the maximum permissable length for
+ an integer on the platform. In such cases the return value from the function
+ call would be 1 (indicating success), but the output length value would be
+ negative. This could cause applications to behave incorrectly or crash.
+ ([CVE-2021-23840])
+
+ *Matt Caswell*
+
+ * Fixed SRP_Calc_client_key so that it runs in constant time. The previous
implementation called BN_mod_exp without setting BN_FLG_CONSTTIME. This
could be exploited in a side channel attack to recover the password. Since
the attack is local host only this is outside of the current OpenSSL
