liboqs is a C-language cryptographic library that provides implementations of post-quantum cryptography algorithms. A control-flow timing lean has been identified in the reference implementation of the Kyber key encapsulation mechanism when it is compiled with Clang 15-18 for `-Os`, `-O1`, and other compilation options. A proof-of-concept local attack on the reference implementation leaks the entire ML-KEM 512 secret key in ~10 minutes using end-to-end decapsulation timing measurements. The issue has been fixed in version 0.10.1. As a possible workaround, some compiler options may produce vectorized code that does not leak secret information, however relying on these compiler options as a workaround may not be reliable.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

    (CVE-2024-36405)

Note that Nessus relies on the presence of the package as reported by the vendor.

The remote SUSE Linux SLED15 / SLED_SAP15 / SLES15 / SLES_SAP15 / openSUSE 15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2025:0005-1 advisory.

    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](https://csrc.nist.gov/pubs/fips/204/final) 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.
