{"id":"CVE-2020-35926","aliases":["RUSTSEC-2020-0089"],"url":"https://o3.security/vulnerability/CVE-2020-35926","summary":"Improper random number generation in nanorand","details":"In versions of nanorand prior to 0.5.1, RandomGen implementations for standard unsigned integers could fail to properly generate numbers, due to using bit-shifting to truncate a 64-bit number, rather than just an as conversion. This often manifested as RNGs returning nothing but 0, including the cryptographically secure ChaCha random number generator.","published":"2021-08-25T20:50:24Z","modified":"2023-11-08T04:03:39.769670Z","cvss":{"score":5.1,"severity":"MEDIUM","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"crates.io","name":"nanorand","fixedVersion":"0.5.1"}],"fix":{"url":"https://github.com/Absolucy/nanorand-rs/commit/5ba218ac29df4786b002d7d12b47fa0c04a331f2","label":"Absolucy/nanorand-rs@5ba218a"},"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2020-35926"},{"type":"WEB","url":"https://github.com/Absolucy/nanorand-rs/commit/5ba218ac29df4786b002d7d12b47fa0c04a331f2"},{"type":"PACKAGE","url":"https://github.com/Absolucy/nanorand-rs"},{"type":"WEB","url":"https://rustsec.org/advisories/RUSTSEC-2020-0089.html"},{"type":"WEB","url":"https://twitter.com/aspenluxxxy/status/1336684692284772352"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2023-11-08T04:03:39.769670Z"}}
