{"id":"RUSTSEC-2021-0009","summary":"panic safety issue in `impl TransformContent\u003cS, D\u003e for [S; (2|3|4)]`","details":"Affected versions of this crate did not guard against double drop while temporarily duplicating objects' ownership using `ptr::read()`. Upon panic in a user-provided function `conversion`, objects that are copied by `ptr::read()` are dropped twice, leading to memory corruption.\n\nThe flaw was corrected in v0.9.2 by using `ManuallyDrop\u003cT\u003e` to enclose objects that are to be temporarily duplicated.","aliases":["CVE-2021-25906","GHSA-fjr6-hm39-4cf9"],"modified":"2023-11-08T04:05:16.857288Z","published":"2021-01-10T12:00:00Z","database_specific":{"license":"CC0-1.0"},"references":[{"type":"PACKAGE","url":"https://crates.io/crates/basic_dsp_matrix"},{"type":"ADVISORY","url":"https://rustsec.org/advisories/RUSTSEC-2021-0009.html"},{"type":"REPORT","url":"https://github.com/liebharc/basic_dsp/issues/47"}],"affected":[{"package":{"name":"basic_dsp_matrix","ecosystem":"crates.io","purl":"pkg:cargo/basic_dsp_matrix"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0.0.0-0"},{"fixed":"0.9.2"}]}],"ecosystem_specific":{"affects":{"functions":[],"arch":[],"os":[]},"affected_functions":null},"database_specific":{"informational":null,"source":"https://github.com/rustsec/advisory-db/blob/osv/crates/RUSTSEC-2021-0009.json","cvss":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","categories":["memory-corruption"]}}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
