This was the result of mishandling a syntactically valid empty\n`BIT STRING` appearing in the `onlySomeReasons` element of a `IssuingDistributionPoint` CRL extension.\n\nThis panic is reachable prior to a CRL's signature being verified.\n\nApplications that do not use CRLs are not affected.\n\nThank you to @tynus3 for the report.","aliases":["GHSA-82j2-j2ch-gfr8"],"modified":"2026-04-22T09:06:54.140749Z","published":"2026-04-22T12:00:00Z","database_specific":{"license":"CC0-1.0"},"references":[{"type":"PACKAGE","url":"https://crates.io/crates/rustls-webpki"},{"type":"ADVISORY","url":"https://rustsec.org/advisories/RUSTSEC-2026-0104.html"}],"affected":[{"package":{"name":"rustls-webpki","ecosystem":"crates.io","purl":"pkg:cargo/rustls-webpki"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0.0.0-0"},{"fixed":"0.103.13"},{"introduced":"0.104.0-alpha.1"},{"fixed":"0.104.0-alpha.7"}]}],"ecosystem_specific":{"affected_functions":null,"affects":{"os":[],"functions":[],"arch":[]}},"database_specific":{"cvss":null,"informational":null,"source":"https://github.com/rustsec/advisory-db/blob/osv/crates/RUSTSEC-2026-0104.json","categories":["denial-of-service"]}}],"schema_version":"1.7.5"}
