{"id":"GHSA-9398-5ghf-7pr6","summary":"conduit-hyper vulnerable to Denial of Service from unchecked request length","details":"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.\n\nIn version 0.4.2, `conduit-hyper` sets an internal limit of 128 MiB per request, otherwise returning status 400 (\"Bad Request\").\n\nThis 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.\n\nThe vulnerability was discovered by Ori Hollander from the JFrog Security Research team.","aliases":["CVE-2022-39294","RUSTSEC-2022-0066"],"modified":"2023-11-08T04:10:17.959579Z","published":"2022-10-31T18:44:47Z","database_specific":{"cwe_ids":["CWE-1284","CWE-400"],"severity":"HIGH","github_reviewed":true,"github_reviewed_at":"2022-10-31T18:44:47Z","nvd_published_at":"2022-10-31T19:15:00Z"},"references":[{"type":"WEB","url":"https://github.com/conduit-rust/conduit-hyper/security/advisories/GHSA-9398-5ghf-7pr6"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-39294"},{"type":"WEB","url":"https://github.com/conduit-rust/conduit-hyper/commit/4d225a53206505d39438ec6694e15f49c038baff"},{"type":"PACKAGE","url":"https://github.com/conduit-rust/conduit-hyper"},{"type":"WEB","url":"https://rustsec.org/advisories/RUSTSEC-2022-0066.html"}],"affected":[{"package":{"name":"conduit-hyper","ecosystem":"crates.io","purl":"pkg:cargo/conduit-hyper"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0.2.0-alpha.3"},{"fixed":"0.4.2"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2022/10/GHSA-9398-5ghf-7pr6/GHSA-9398-5ghf-7pr6.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
