An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2019-16910 in the wild and no public exploit code.\n\nAffected product: Arm Mbed Tls. 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-2019-16910/ (Markdown: https://insights.sbomify.com/CVE-2019-16910/index.md)","id":"CVE-2019-16910","markdown":"https://insights.sbomify.com/CVE-2019-16910/index.md","name":"CVE-2019-16910","record":{"aliases":["ALPINE-CVE-2019-16910","DEBIAN-CVE-2019-16910","GHSA-jg4p-c829-4q39","JLSEC-2025-198","UBUNTU-CVE-2019-16910"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":true,"product_category":"Mbed TLS library","requires_auth":"none","summary":"Insufficient entropy in deterministic ECDSA blinding allows private key recovery via side-channel attacks when signing the same message repeatedly.","user_interaction":"required","vuln_class":"weak_cryptography"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"mbed_crypto","vendor":"arm"},{"product":"mbed_tls","vendor":"arm"},{"product":"debian_linux","vendor":"debian"},{"product":"fedora","vendor":"fedoraproject"},{"product":"mbed_tls","vendor":"trustedfirmware"}],"cvss":{"score":5.3,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[],"description":"Arm Mbed TLS before 2.19.0 and Arm Mbed Crypto before 2.0.0, when deterministic ECDSA is enabled, use an RNG with insufficient entropy for blinding, which might allow an attacker to recover a private key via side-channel attacks if a victim signs the same message many times.
