+
+ Major changes between OpenSSL 1.1.0i and OpenSSL 1.1.1 [11 Sep 2018]
+
+ o Support for TLSv1.3 added (see https://wiki.openssl.org/index.php/TLS1.3

+ o Fully compliant implementation of RFC8446 (TLSv1.3) on by default
+ o Early data (0-RTT)
+ o Post-handshake authentication and key update
+ o Middlebox Compatibility Mode
+ o TLSv1.3 PSKs
+ o Support for all five RFC8446 ciphersuites
+ o RSA-PSS signature algorithms (backported to TLSv1.2)
+ o Configurable session ticket support
+ o Stateless server support
+ o Rewrite of the packet construction code for "safer" packet handling
+ o Rewrite of the extension handling code
+ o Complete rewrite of the OpenSSL random number generator to introduce the
+ following capabilities
+ o The default RAND method now utilizes an AES-CTR DRBG according to
+ NIST standard SP 800-90Ar1.
+ o Support for multiple DRBG instances with seed chaining.
+ o There is a public and private DRBG instance.
+ o The DRBG instances are fork-safe.
+ o Keep all global DRBG instances on the secure heap if it is enabled.
+ o The public and private DRBG instance are per thread for lock free
+ operation
+ o Support for various new cryptographic algorithms including:
+ o SHA3
+ o SHA512/224 and SHA512/256
+ o EdDSA (both Ed25519 and Ed448) including X509 and TLS support
+ o X448 (adding to the existing X25519 support in 1.1.0)
+ o Multi-prime RSA
+ o SM2
+ o SM3
+ o SM4
+ o SipHash
+ o ARIA (including TLS support)
+ o Significant Side-Channel attack security improvements
+ o Add a new ClientHello callback to provide the ability to adjust the SSL
+ object at an early stage.
+ o Add 'Maximum Fragment Length' TLS extension negotiation and support
+ o A new STORE module, which implements a uniform and URI based reader of
+ stores that can contain keys, certificates, CRLs and numerous other
+ objects.
o Move the display of configuration data to configdata.pm.
o Allow GNU style "make variables" to be used with Configure.
- o Add a STORE module (OSSL_STORE)
o Claim the namespaces OSSL and OPENSSL, represented as symbol prefixes
- o Add multi-prime RSA (RFC 8017) support
- o Add SM3 implemented according to GB/T 32905-2016
- o Add SM4 implemented according to GB/T 32907-2016.
- o Add 'Maximum Fragment Length' TLS extension negotiation and support
- o Add ARIA support
- o Add SHA3
o Rewrite of devcrypto engine
- o Add support for SipHash
- o Grand redesign of the OpenSSL random generator
+

+
+ o Client DoS due to large DH parameter (CVE-2018-0732)
+ o Cache timing vulnerability in RSA Key Generation (CVE-2018-0737)
Major changes between OpenSSL 1.1.0g and OpenSSL 1.1.0h [under development]
+ o Constructed ASN.1 types with a recursive definition could exceed the
+ stack (CVE-2018-0739)
+ o Incorrect CRYPTO_memcmp on HP-UX PA-RISC (CVE-2018-0733)
o rsaz_1024_mul_avx2 overflow bug on x86_64 (CVE-2017-3738)
