Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2025-5449 in the wild and no public exploit code.\n\nAffected product: Red Hat Enterprise Linux 10. 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-2025-5449/ (Markdown: https://insights.sbomify.com/CVE-2025-5449/index.md)","id":"CVE-2025-5449","markdown":"https://insights.sbomify.com/CVE-2025-5449/index.md","name":"CVE-2025-5449","record":{"aliases":["BELL-CVE-2025-5449","DEBIAN-CVE-2025-5449","GHSA-q9x7-4rf7-4xq2","JLSEC-2025-100","MINI-39pq-5g6j-mg8g"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"libssh SFTP server","requires_auth":"low_privilege","summary":"An integer overflow in libssh's SFTP server allows remote attackers to cause a denial of service via large payloads on 32-bit systems.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"libssh","vendor":"libssh"}],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-190","name":"Integer Overflow or Wraparound"}],"description":"A flaw was found in the SFTP server message decoding logic of libssh.
