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-2020-35907 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- futures-task (crates.io): affected all versions; fixed in 0.3.5\n- futures-task (crates.io): affected all versions; fixed in 0.3.5\n- futures-task (crates.io): affected from 0.0.0-0; fixed in 0.3.5\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-2020-35907/ (Markdown: https://insights.sbomify.com/CVE-2020-35907/index.md)","id":"CVE-2020-35907","markdown":"https://insights.sbomify.com/CVE-2020-35907/index.md","name":"CVE-2020-35907","record":{"aliases":["GHSA-p9m5-3hj7-cp5r","RUSTSEC-2020-0061","UBUNTU-CVE-2020-35907"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Rust futures-task crate","requires_auth":"low_privilege","summary":"A NULL pointer dereference in the futures-task crate allows attackers to cause a denial of service via noop_waker_ref.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"futures-task","vendor":"rust-lang"}],"cvss":{"score":5.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-476","name":"NULL Pointer Dereference"}],"description":"An issue was discovered in the futures-task crate before 0.3.5 for Rust. futures_task::noop_waker_ref allows a NULL pointer dereference.","ecosystems":["crates.io"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"futures_task::noop_waker_ref can segfault due to dereferencing a NULL pointer","id":"CVE-2020-35907","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"crates.io","product":null,"products":[],"type":"null_dereference","year":"2020"},"n_packages":3,"n_references":1,"next":{"headline":"Improper `Sync` implementation on `FuturesUnordered` in futures-utils can cause data corruption","id":"CVE-2020-35908"},"packages":[{"ecosystem":"crates.io","fixed":["0.3.5"],"introduced":["0"],"last_affected":[],"package":"futures-task","purl":null,"source":"GHSA-p9m5-3hj7-cp5r"},{"ecosystem":"crates.io","fixed":["0.3.5"],"introduced":["0"],"last_affected":[],"package":"futures-task","purl":"pkg:cargo/futures-task","source":"GHSA-p9m5-3hj7-cp5r"},{"ecosystem":"crates.io","fixed":["0.3.5"],"introduced":["0.0.0-0"],"last_affected":[],"package":"futures-task","purl":"pkg:cargo/futures-task","source":"RUSTSEC-2020-0061"}],"prev":{"headline":"futures_task::waker may cause a use-after-free if used on a type that isn't 'static","id":"CVE-2020-35906"},"products":["n/a"],"published":"2020-12-31","related":[{"cvss_score":7.8,"headline":"futures_task::waker may cause a use-after-free if used on a type that isn't 'static","id":"CVE-2020-35906","kev_date_added":null,"published":"2020-12-31"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"open","licence":"CC0 1.0","name":"RustSec","prefix":"RUSTSEC"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["n/a"]},"summary":"A NULL pointer dereference in the futures-task crate allows attackers to cause a denial of service via noop_waker_ref.","url":"https://insights.sbomify.com/CVE-2020-35907/"}
