Changes since v5.5.0:
wolfSSL Release 5.5.1 (Sep 28, 2022) Latest
Vulnerabilities
* [Med] Denial of service attack and buffer overflow against TLS 1.3 servers
using session ticket resumption. When built with --enable-session-ticket and
making use of TLS 1.3 server code in wolfSSL, there is the possibility of a
malicious client to craft a malformed second ClientHello packet that causes
the server to crash. This issue is limited to when using both
--enable-session-ticket and TLS 1.3 on the server side. Users with TLS 1.3
servers, and having --enable-session-ticket, should update to the latest
version of wolfSSL. Thanks to Max at Trail of Bits for the report and
"LORIA, INRIA, France" for research on tlspuffin.
New Feature Additions
* Add support for non-blocking ECC key gen and shared secret gen for
P-256/384/521
* Add support for non-blocking ECDHE/ECDSA in TLS/DTLS layer.
* Port to NXP RT685 with FreeRTOS
* Add option to build post quantum Kyber API (--enable-kyber)
* Add post quantum algorithm sphincs to wolfCrypt
* Config. option to force no asm with SP build (--enable-sp=noasm)
* Allow post quantum keyshare for DTLS 1.3
Enhancements
* DTLSv1.3: Do HRR Cookie exchange by default
* Add wolfSSL_EVP_PKEY_new_CMAC_key to OpenSSL compatible API
* Update ide win10 build files to add missing sp source files
* Improve Workbench docs
* Improve EVP support for CHACHA20_POLY1305
* Improve wc_SetCustomExtension documentation
* RSA-PSS with OCSP and add simple OCSP response DER verify test case
* Clean up some FIPS versioning logic in configure.ac and WIN10 user_settings.h
* Don't over-allocate memory for DTLS fragments
* Add WOLFSSL_ATECC_TFLXTLS for Atmel port
* SHA-3 performance improvements with x86_64 assembly
* Add code to fallback to S/W if TSIP cannot handle

* Add to RSAES-OAEP key parsing for pkcs7
* Add missing DN nid to work with PrintName()
* SP int: default to 16 bit word size when NO_64BIT defined
* Limit the amount of fragments we store per a DTLS connection and error out
when max limit is reached
* Detect when certificate's RSA public key size is too big and fail on loading
of certificate
