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-2021-32714/ (Markdown: https://insights.sbomify.com/CVE-2021-32714/index.md)","id":"CVE-2021-32714","markdown":"https://insights.sbomify.com/CVE-2021-32714/index.md","name":"CVE-2021-32714","record":{"aliases":["DEBIAN-CVE-2021-32714","GHSA-5h46-h7hh-c6x9","RUSTSEC-2021-0079","UBUNTU-CVE-2021-32714"],"analysis":null,"analysis_generated_by":null,"assigner":"GitHub_M","cpe":[{"product":"hyper","vendor":"hyper"}],"cvss":{"score":5.9,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-190","name":"Integer Overflow or Wraparound"}],"description":"hyper is an HTTP library for Rust. In versions prior to 0.14.10, hyper's HTTP server and client code had a flaw that could trigger an integer overflow when decoding chunk sizes that are too big. This allows possible data loss, or if combined with an upstream HTTP proxy that allows chunk sizes larger than hyper does, can result in \"request smuggling\" or \"desync attacks.\" The vulnerability is patched in version 0.14.10. Two possible workarounds exist. One may reject requests manually that contain a `Transfer-Encoding` header or ensure any upstream proxy rejects `Transfer-Encoding` chunk sizes greater than what fits in 64-bit unsigned integers.","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":"Integer Overflow in Chunked Transfer-Encoding","id":"CVE-2021-32714","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"crates.io","product":null,"products":[],"type":null,"year":"2021"},"n_packages":3,"n_references":1,"next":{"headline":"Lenient Parsing of Content-Length Header When Prefixed with Plus Sign","id":"CVE-2021-32715"},"packages":[{"ecosystem":"crates.io","fixed":["0.14.10"],"introduced":["0"],"last_affected":[],"package":"hyper","purl":null,"source":"GHSA-5h46-h7hh-c6x9"},{"ecosystem":"crates.io","fixed":["0.14.10"],"introduced":["0"],"last_affected":[],"package":"hyper","purl":"pkg:cargo/hyper","source":"GHSA-5h46-h7hh-c6x9"},{"ecosystem":"crates.io","fixed":["0.14.10"],"introduced":["0.0.0-0"],"last_affected":[],"package":"hyper","purl":"pkg:cargo/hyper","source":"RUSTSEC-2021-0079"}],"prev":{"headline":"Authenticated Stored XSS","id":"CVE-2021-32713"},"products":["hyper"],"published":"2021-07-07","related":[{"cvss_score":9.8,"headline":"HTTP Request Smuggling in hyper","id":"CVE-2020-35863","kev_date_added":null,"published":"2020-12-31"},{"cvss_score":7.5,"headline":"Denial of service in n/a","id":"CVE-2022-31394","kev_date_added":null,"published":"2023-02-21"},{"cvss_score":5.3,"headline":"Headers containing newline characters can split messages in hyper","id":"CVE-2017-18587","kev_date_added":null,"published":"2019-08-26"},{"cvss_score":4.8,"headline":"Multiple Transfer-Encoding headers misinterprets request payload","id":"CVE-2021-21299","kev_date_added":null,"published":"2021-02-11"},{"cvss_score":4.8,"headline":"HTTPS MitM vulnerability due to lack of hostname verification","id":"CVE-2016-10932","kev_date_added":null,"published":"2019-08-26"},{"cvss_score":3.1,"headline":"Lenient Parsing of Content-Length Header When Prefixed with Plus Sign","id":"CVE-2021-32715","kev_date_added":null,"published":"2021-07-07"}],"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":"2024-08-03","vendors":["hyperium"]},"summary":null,"url":"https://insights.sbomify.com/CVE-2021-32714/"}
