It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2024-1544 in the wild and no public exploit code.\n\nAffected product: Wolfssl Wolfssl. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2024-1544/ (Markdown: https://insights.sbomify.com/CVE-2024-1544/index.md)","id":"CVE-2024-1544","markdown":"https://insights.sbomify.com/CVE-2024-1544/index.md","name":"CVE-2024-1544","record":{"aliases":["DEBIAN-CVE-2024-1544","GHSA-grjj-54gm-q5vf","JLSEC-2026-682","UBUNTU-CVE-2024-1544"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"wolfSSL cryptographic library","requires_auth":"high_privilege","summary":"Side-channel leakage in ECDSA nonce generation allows attackers to recover private keys via lattice reduction.","user_interaction":"not_required","vuln_class":"weak_cryptography"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"wolfSSL","cpe":[{"product":"wolfssl","vendor":"wolfssl"}],"cvss":{"score":4.1,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:H/PR:H/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-203","name":"Observable Discrepancy"}],"description":"Generating the ECDSA nonce k samples a random number r and then \ntruncates this randomness with a modular reduction mod n where n is the \norder of the elliptic curve.

The division used \nduring the reduction estimates a factor q_e by dividing the upper two \ndigits (a digit having e.g. a size of 8 byte) of r by the upper digit of \nn and then decrements q_e in a loop until it has the correct size. \nObserving the number of times q_e is decremented through a control-flow \nrevealing side-channel reveals a bias in the most significant bits of \nk.
