security/wolfssl: Update to 5.7.0

Changes since 5.6.6:

wolfSSL Release 5.7.0 (Mar 20, 2024)

NOTE: * --enable-heapmath is being deprecated and will be removed by end of
2024

NOTE: In future releases, --enable-des3 (which is disabled by default) will
be insufficient in itself to enable DES3 in TLS cipher suites. A new option,
--enable-des3-tls-suites, will need to be supplied in addition. This option
should only be used in backward compatibility scenarios, as it is inherently
insecure.

NOTE: This release switches the default ASN.1 parser to the new ASN template
code. If the original ASN.1 code is preferred define WOLFSSL_ASN_ORIGINAL to
use it. See PR #7199.

Vulnerabilities

  * [High] CVE-2024-0901 Potential denial of service and out of bounds read.
    Affects TLS 1.3 on the server side when accepting a connection from a
    malicious TLS 1.3 client. If using TLS 1.3 on the server side it is
    recommended to update the version of wolfSSL used. Fixed in this GitHub
    pull request #7099

  * [Med] CVE-2024-1545 Fault Injection vulnerability in
    RsaPrivateDecryption function that potentially allows an attacker thathas
    access to the same system with a victims process to perform aRowhammer
    fault injection. Thanks to Junkai Liang, Zhi Zhang, Xin Zhang,Qingni Shen
    for the report (Peking University, The University of WesternAustralia)."
    Fixed in this GitHub pull request #7167

  * [Med] Fault injection attack with EdDSA signature operations. This
    affects ed25519 sign operations where the system could be susceptible to
    Rowhammer attacks. Thanks to Junkai Liang, Zhi Zhang, Xin Zhang, Qingni
    Shen for the report (Peking University, The University of Western
    Australia). Fixed in this GitHub pull request #7212

New Feature Additions

  * Added --enable-experimental configure flag to gate out features that are
    currently experimental. Now liboqs, kyber, lms, xmss, and dual-alg-certs
    require the --enable-experimental flag.

POST QUANTUM SUPPORT ADDITIONS

  * Experimental framework for using wolfSSL’s XMSS implementation (PR 7161)

Log message:
security/wolfssl: Update to 5.6.6

Changes since 5.6.4:

wolfSSL Release 5.6.6 (Dec 19, 2023)

NOTE: * --enable-heapmath is being deprecated and will be removed by 2024

REMINDER: When working with AES Block Cipher algorithms, wc_AesInit() should
always be called first to initialize the Aes structure, before calling other
Aes API functions. Recently we found several places in our documentation,
comments, and codebase where this pattern was not observed. We have since
fixed this omission in several PRs for this release.

Vulnerabilities

  * [Medium] CVE-2023-6935: After review of the previous RSA timing fix in
    wolfSSL 5.6.4, additional changes were found to be required. A complete
    resistant change is delivered in this release. This fix is for the Marvin
    attack, leading to being able to decrypt a saved TLS connection and
    potentially forge a signature after probing with a very large number of
    trial connections. This issue is around RSA decryption and affects the
    optional static RSA cipher suites on the server side, which are considered
    weak, not recommended to be used and are off by default in wolfSSL (even
    with --enable-all). Static RSA cipher suites were also removed from the
    TLS 1.3 protocol and are only present in TLS 1.2 and lower. All padding
    versions of RSA decrypt are affected since the code under review is
    outside of the padding processing. Information about the private keys is
    NOT compromised in affected code. It is recommended to disable static RSA
    cipher suites and update the version of wolfSSL used if using RSA private
    decryption alone outside of TLS. Thanks to Hubert Kario for the report.
    The fix for this issue is located in the following GitHub Pull Request:
    #6955.

  * [Low] CVE-2023-6936: A potential heap overflow read is possible in servers
    connecting over TLS 1.3 when the optional WOLFSSL_CALLBACKS has been
    defined. The out of bounds read can occur when a server receives a
    malicious malformed ClientHello. Users should either discontinue use of
    WOLFSSL_CALLBACKS on the server side or update versions of wolfSSL to
    5.6.6. Thanks to the tlspuffin fuzzer team for the report which was
    designed and developed by; Lucca Hirschi (Inria, LORIA), Steve Kremer
    (Inria, LORIA), and Max Ammann (Trail of Bits). The fix for this issue is
    located in the following GitHub Pull Request: #6949.

  * [Low] A side channel vulnerability with AES T-Tables is possible in a very
    controlled environment where precision sub-cache-line inspection can
    happen, such as inside an Intel SGX enclave. This can lead to recovery of
    the AES key. To prevent this type of attack, wolfSSL added an AES
    bitsliced implementation which can be enabled with the
    "--enable-aes-bitsliced" configure option. Thanks to Florian Sieck,
    Zhiyuan Zhang, Sebastian Berndt, Chitchanok Chuengsatiansup, Thomas
    Eisenbarth, and Yuval Yarom for the  report (Universities of Lübeck,
    Melbourne, Adelaide and Bochum). The fix for this issue is located in the
    following GitHub Pull Request: #6854.

  * [Low] CVE-2023-6937: wolfSSL prior to 5.6.6 did not check that messages in
    a single (D)TLS record do not span key boundaries. As a result, it was
    possible to combine (D)TLS messages using different keys into one (D)TLS
    record. The most extreme edge case is that, in (D)TLS 1.3, it was possible
    that an unencrypted (D)TLS 1.3 record from the server containing first a
    ServerHello message and then the rest of the first server flight would be
    accepted by a wolfSSL client. In (D)TLS 1.3 the handshake is encrypted
    after the ServerHello but a wolfSSL client would accept an unencrypted
    flight from the server. This does not compromise key negotiation and
    authentication so it is assigned a low severity rating. Thanks to Johannes
    Wilson for the report (Sectra Communications and Linköping University).
    The fix for this issue is located in the following GitHub Pull Request:
    #7029.

    using RSA private decryption alone outside of TLS. The fix is located in
    this pull request (#6896)

security/wolfssl: Update to v5.6.3

Changes since v5.6.0:

wolfSSL Release 5.6.3 (Jun 16, 2023)

Release 5.6.3 of wolfSSL embedded TLS has 4 bug fixes:

* Fix for setting the atomic macro options introduced in release 5.6.2. This
  issue affects GNU gcc autoconf builds. The fix resolves a potential mismatch of
  the generated macros defined in options.h file and the macros used when the
  wolfSSL library is compiled. In version 5.6.2 this mismatch could result in
  unstable runtime behavior.
* Fix for invalid suffix error with Windows build using the macro
  GCM_TABLE_4BIT.
* Improvements to Encrypted Memory support (WC_PROTECT_ENCRYPTED_MEM)
  implementations for modular exponentiation in SP math-all (sp_int.c) and TFM
  (tfm.c).
* Improvements to SendAlert for getting output buffer.

wolfSSL Release 5.6.2 (Jun 09, 2023)

Release 5.6.2 has been developed according to wolfSSL's development and QA
process (see link below) and successfully passed the quality criteria.
https://www.wolfssl.com/about/wolfssl-software-development-process-quality-assurance

NOTE: * --enable-heapmath is being deprecated and will be removed by 2024

Release 5.6.2 of wolfSSL embedded TLS has bug fixes and new features including:

Vulnerabilities
* [Low] In cases where a malicious agent could analyze cache timing at a very
  detailed level, information about the AES key used could be leaked during T/S
  Box lookups. One such case was shown on RISC-V hardware using the MicroWalk tool
  (https://github.com/microwalk-project/Microwalk). A hardened version of T/S Box
  lookups was added in wolfSSL to help mitigate this potential attack and is now
  on by default with RISC-V builds and can be enabled on other builds if desired
  by compiling wolfSSL with the macro WOLFSSL_AES_TOUCH_LINES. Thanks to Jan
  Wichelmann, Christopher Peredy, Florian Sieck, Anna Pätschke, Thomas Eisenbarth
  (University of Lübeck): MAMBO-V: Dynamic Side-Channel Leakage Analysis on
  RISC-V. Fixed in the following GitHub pull request
  https://github.com/wolfSSL/wolfssl/pull/6309
* [High] In previous versions of wolfSSL if a TLS 1.3 client gets neither a PSK
  (pre shared key) extension nor a KSE (key share extension) when connecting to a
  malicious server, a default predictable buffer gets used for the IKM value when
  generating the session master secret. Using a potentially known IKM value when
  generating the session master secret key compromises the key generated, allowing
  an eavesdropper to reconstruct it and potentially allowing surreptitious access
  to or meddling with message contents in the session. This issue does not affect
  client validation of connected servers, nor expose private key information, but
  could result in an insecure TLS 1.3 session when not controlling both sides of
  the connection. We recommend that TLS 1.3 client side users update the version
  of wolfSSL used. Thanks to Johannes from Sectra Communications and Linköping
  University for the report. Fixed in the following GitHub pull request
  https://github.com/wolfSSL/wolfssl/pull/6412

security/wolfssl: Update to v5.5.3

Changes since v5.5.1:

wolfSSL Release 5.5.3 (Nov 2, 2022)

Release 5.5.3 of wolfSSL embedded TLS has the following bug fix:

Fixes

* Fix for possible buffer zeroization overrun introduced at the end of v5.5.2
  release cycle in GitHub pull request 5743
  (https://github.com/wolfSSL/wolfssl/pull/5743) and fixed in pull request 5757
  (https://github.com/wolfSSL/wolfssl/pull/5757). In the case where a specific
  memory allocation failed or a hardware fault happened there was the potential
  for an overrun of 0’s when masking the buffer used for (D)TLS 1.2 and lower
  operations. (D)TLS 1.3 only and crypto only users are not affected by the
  issue. This is not related in any way to recent issues reported in OpenSSL.

wolfSSL Release 5.5.2 (Oct 28, 2022)

Release 5.5.2 of wolfSSL embedded TLS has bug fixes and new features including:

Vulnerabilities
* [Med] In the case that the WOLFSSL_CALLBACKS macro is set when building
  wolfSSL, there is a potential heap over read of 5 bytes when handling TLS 1.3
  client connections. This heap over read is limited to wolfSSL builds
  explicitly setting the macro WOLFSSL_CALLBACKS, the feature does not get
  turned on by any other build options. The macro WOLFSSL_CALLBACKS is intended
  for debug use only, but if having it enabled in production, users are
  recommended to disable WOLFSSL_CALLBACKS. Users enabling WOLFSSL_CALLBACKS are
  recommended to update their version of wolfSSL. Thanks to Lucca Hirschi and
  Steve Kremer from LORIA, Inria and Max Ammann from Trail of Bits for finding
  and reporting the bug with the tlspuffin tool developed partly at LORIA and
  Trail of Bits. CVE 2022-42905

Log message:
security/wolfssl: Update to v5.5.1

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

Log message:
security/wolfssl: Update to v5.5.0

Changes since v5.4.0:

wolfSSL Release 5.5.0 (Aug 30, 2022)

Note:
** If not free’ing FP_ECC caches per thread by calling wc_ecc_fp_free there is a
   possible memory leak during TLS 1.3 handshakes which use ECC. Users are urged
   to confirm they are free’ing FP_ECC caches per thread if enabled to avoid
   this issue.

Release 5.5.0 of wolfSSL embedded TLS has bug fixes and new features including:

Vulnerabilities
* [Low] Fault injection attack on RAM via Rowhammer leads to ECDSA key
  disclosure. Users doing operations with private ECC keys such as server side
  TLS connections and creating ECC signatures, who also have hardware that could
  be targeted with a sophisticated Rowhammer attack should update the version of
  wolfSSL and compile using the macro WOLFSSL_CHECK_SIG_FAULTS. Thanks to Yarkin
  Doroz, Berk Sunar, Koksal Must, Caner Tol, and Kristi Rahman all affiliated
  with the Vernam Applied Cryptography and Cybersecurity Lab at Worcester
  Polytechnic Institute for the report.
* [Low] In wolfSSL version 5.3.0 if compiled with --enable-session-ticket and
  the client has non-empty session cache, with TLS 1.2 there is the possibility
  of a man in the middle passing a large session ticket to the client and
  causing a crash due to an invalid free. There is also the potential for a
  malicious TLS 1.3 server to crash a client in a similar manner except in TLS
  1.3 it is not susceptible to a man in the middle attack. Users on the client
  side with –enable-session-ticket compiled in and using wolfSSL version 5.3.0
  should update their version of wolfSSL. Thanks to Max at Trail of Bits for the
  report and "LORIA, INRIA, France" for research on tlspuffin.
* [Low] If using wolfSSL_clear to reset a WOLFSSL object (vs the normal
  wolfSSL_free/wolfSSL_new) it can result in runtime issues. This exists with
  builds using the wolfSSL compatibility layer (--enable-opnesslextra) and only
  when the application is making use of wolfSSL_clear instead of
  SSL_free/SSL_new. In the case of a TLS 1.3 resumption, after continuing to use
  the WOLFSSH object after having called wolfSSL_clear, an application could
  crash. It is suggested that users calling wolfSSL_clear update the version of
  wolfSSL used. Thanks to Max at Trail of Bits for the report and "LORIA, INRIA,
  France" for research on tlspuffin.
* Potential DoS attack on DTLS 1.2. In the case of receiving a malicious
  plaintext handshake message at epoch 0 the connection will enter an error
  state reporting a duplicate message. This affects both server and client
  side. Users that have DTLS enabled and in use should update their version of
  wolfSSL to mitigate the potential for a DoS attack.

New Feature Additions
* QUIC support added, for using wolfSSL with QUIC implementations like ngtcp2
* SE050 port additions and fixes
* Added support for Dilithium post quantum algorithm use with TLS
