An update that solves three vulnerabilities can now be installed.

## Description:

This update for liboqs, oqs-provider fixes the following issues:

This update supplies the new FIPS standardized ML-KEM, ML-DSA, SHL-DSA
algorithms.

This update liboqs to 0.12.0:

  * This release updates the ML-DSA implementation to the final FIPS 204
    version. This release still includes the NIST Round 3 version of Dilithium
    for interoperability purposes, but we plan to remove Dilithium Round 3 in a
    future release.
  * This will be the last release of liboqs to include Kyber (that is, the NIST
    Round 3 version of Kyber, prior to its standardization by NIST as ML-KEM in
    FIPS 203). Applications should switch to ML-KEM (FIPS 203).
  * The addition of ML-DSA FIPS 204 final version to liboqs has introduced a new
    signature API which includes a context string parameter. We are planning to
    remove the old version of the API without a context string in the next
    release to streamline the API and bring it in line with NIST specifications.
    Users who have an opinion on this removal are invited to provide input at
    https://github.com/open-quantum-safe/liboqs/issues/2001.

Security issues:

  * CVE-2024-54137: Fixed bug in HQC decapsulation that leads to incorrect
    shared secret value during decapsulation when called with an invalid
    ciphertext. (bsc#1234292)
  * new library major version 7

Updated to 0.11.0:

  * This release updates ML-KEM implementations to their final FIPS 203
    https://csrc.nist.gov/pubs/fips/203/final versions .
  * This release still includes the NIST Round 3 version of Kyber for
    interoperability purposes, but we plan to remove Kyber Round 3 in a future
    release.
  * Additionally, this release adds support for MAYO and CROSS digital signature
    schemes from [NIST Additional Signatures Round 1
    https://csrc.nist.gov/Projects/pqc-dig-sig/round-1-additional-signatures
    along with stateful hash-based signature schemes XMSS
    https://datatracker.ietf.org/doc/html/rfc8391 and LMS
    https://datatracker.ietf.org/doc/html/rfc8554.
  * Finally, this release provides formally verified implementations of
    Kyber-512 and Kyber-768 from libjade https://github.com/formosa-crypto/libjade/releases/tag/release%2F2023.05-2
  * LMS and XMSS are disabled by default due to the security risks associated
    with their use in software. See the note on stateful hash-based signatures
    in CONFIGURE.md
  * Key encapsulation mechanisms:
  * Kyber: Added formally-verified portable C and AVX2 implementations of
    Kyber-512 and Kyber-768 from libjade.
  * ML-KEM: Updated portable C and AVX2 implementations of ML-KEM-512, ML-
    KEM-768, and ML-KEM-1024 to FIP 203 version.
  * Kyber: Patched ARM64 implementations of Kyber-512, Kyber-768, and Kyber-1024
    to work with AddressSanitizer.
  * Digital signature schemes:
  * LMS/XMSS: Added implementations of stateful hash-based signature schemes:
    XMSS and LMS
  * MAYO: Added portable C and AVX2 implementations of MAYO signature scheme
    from NIST Additional Signatures Round 1.
  * CROSS: Added portable C and AVX2 implementations of CROSS signature scheme
    from NIST Additional Signatures Round 1.
  * Other changes:
  * Added callback API to use custom implementations of AES, SHA2, and SHA3.
  * Refactor SHA3 implementation to use OpenSSL's EVP_DigestSqueeze() API.

  * new library major version 6

Updated to 0.10.1:

  * This release is a security release which fixes potential non-constant-time
    behaviour in ML-KEM and Kyber. (bsc#1226162 CVE-2024-36405) It also includes
    a fix for incorrectly named macros in the ML-DSA implementation.

updated to 0.10.0:

Key encapsulation mechanisms:

  * BIKE: Updated portable C implementation to include constant-time fixes from
    upstream.
  * HQC: Updated to NIST Round 4 version.
  * ML-KEM: Added portable C and AVX2 implementations of Initial Public Draft
    (IPD) versions of ML-KEM-512, ML-KEM-768, and ML-KEM-1024.

Digital signature schemes:

  * Falcon: Updated portable C, AVX2, and AArch64 implementations to support
    fixed-length (PADDED-format) signatures. Fixed the maximum length of
    variable-length signatures to comply with the NIST Round 3 specification.
  * ML-DSA: Added portable C and AVX2 implementations of Initial Public Draft
    (IPD) versions of ML-DSA-44, ML-DSA-65, and ML-DSA-87.

Other changes:

  * Improved thread safety.
  * Removed support for the "NIST-KAT" DRBG.
  * Added extended KAT test programs.

  * library major version changed from 4 to 5

This update also updates oqs-provider to 0.7.0:

  * Adds support for MAYO from Round 1 of NIST’s Post-Quantum Signature On-Ramp
    process.
  * Adds support for CROSS from Round 1 of NIST’s Post-Quantum Signature On-Ramp
    process.
  * Updates ML-KEM's code points in line with internet draft draft-kwiatkowski-
    tls-ecdhe-mlkem-02.
  * Reverses keyshares for X25519MLKEM768 and X448-ML-KEM-768 TLS hybrids in
    line with draft-kwiatkowski-tls-ecdhe-mlkem-02.
