Prior to version 0.4.2, `conduit-hyper` did not check any limit on a request's length before calling [`hyper::body::to_bytes`](https://docs.rs/hyper/latest/hyper/body/fn.to_bytes.html). An attacker could send a malicious request with an abnormally large `Content-Length`, which could lead to a panic if memory allocation failed for that request. In version 0.4.2, `conduit-hyper` sets an internal limit of 128 MiB per request, otherwise returning status 400 (\"Bad Request\"). This crate is part of the implementation of Rust's [crates.io](https://crates.io/), but that service is not affected due to its existing cloud infrastructure, which already drops such malicious requests. Even with the new limit in place, `conduit-hyper` is not recommended for production use, nor to directly serve the public Internet.","state":"PUBLIC","assigner":"security-advisories@github.com","published_at":"2022-10-31 19:15:00","updated_at":"2023-07-11 20:51:00"},"problem_types":["CWE-1284"],"metrics":[],"references":[{"url":"https://github.com/conduit-rust/conduit-hyper/security/advisories/GHSA-9398-5ghf-7pr6","name":"https://github.com/conduit-rust/conduit-hyper/security/advisories/GHSA-9398-5ghf-7pr6","refsource":"CONFIRM","tags":[],"title":"Denial of Service from unchecked request length · Advisory · conduit-rust/conduit-hyper · GitHub","mime":"text/html","httpstatus":"200","archivestatus":"404"},{"url":"https://www.cve.org/CVERecord?id=CVE-2022-39294","name":"CVE Program record","refsource":"CVE.ORG","tags":["canonical"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2022-39294","name":"NVD vulnerability detail","refsource":"NVD","tags":["canonical","analysis"]}],"affected":[],"timeline":[],"solutions":[],"workarounds":[],"exploits":[],"credits":[],"nvd_cpes":[{"cve_year":"2022","cve_id":"39294","vulnerable":"1","versionEndIncluding":"","cpe1":"cpe","cpe2":"2.3","cpe3":"a","cpe4":"conduit-hyper_project","cpe5":"conduit-hyper","cpe6":"*","cpe7":"*","cpe8":"*","cpe9":"*","cpe10":"*","cpe11":"rust","cpe12":"*","cpe13":"*"},{"cve_year":"2022","cve_id":"39294","vulnerable":"1","versionEndIncluding":"","cpe1":"cpe","cpe2":"2.3","cpe3":"a","cpe4":"conduit-hyper_project","cpe5":"conduit-hyper","cpe6":"0.2.0","cpe7":"-","cpe8":"*","cpe9":"*","cpe10":"*","cpe11":"rust","cpe12":"*","cpe13":"*"},{"cve_year":"2022","cve_id":"39294","vulnerable":"1","versionEndIncluding":"","cpe1":"cpe","cpe2":"2.3","cpe3":"a","cpe4":"conduit-hyper_project","cpe5":"conduit-hyper","cpe6":"0.2.0","cpe7":"alpha3","cpe8":"*","cpe9":"*","cpe10":"*","cpe11":"rust","cpe12":"*","cpe13":"*"},{"cve_year":"2022","cve_id":"39294","vulnerable":"1","versionEndIncluding":"","cpe1":"cpe","cpe2":"2.3","cpe3":"a","cpe4":"conduit-hyper_project","cpe5":"conduit-hyper","cpe6":"0.2.0","cpe7":"alpha4","cpe8":"*","cpe9":"*","cpe10":"*","cpe11":"rust","cpe12":"*","cpe13":"*"}],"vendor_comments":[],"enrichments":{"kev":null,"epss":null,"legacy_qids":[]},"source_records":{"cve_program":{"CVE_data_meta":{"ASSIGNER":"security-advisories@github.com","ID":"CVE-2022-39294","STATE":"PUBLIC","TITLE":"(DoS) Denial of Service from unchecked request length in conduit-hyper"},"affects":{"vendor":{"vendor_data":[{"product":{"product_data":[{"product_name":"conduit-hyper","version":{"version_data":[{"version_value":">= 0.2.0-alpha.3, < 0.4.2"}]}}]},"vendor_name":"conduit-rust"}]}},"data_format":"MITRE","data_type":"CVE","data_version":"4.0","description":{"description_data":[{"lang":"eng","value":"conduit-hyper integrates a conduit application with the hyper server.
