In crossbeam-channel before version 0.4.4, the bounded channel incorrectly assumes that `Vec::from_iter` has allocated capacity that same as the number of iterator elements. `Vec::from_iter` does not actually guarantee that and may allocate extra memory. The destructor of the `bounded` channel reconstructs `Vec` from the raw pointer based on the incorrect assumes described above. This is unsound and causing deallocation with the incorrect capacity when `Vec::from_iter` has allocated different sizes with the number of iterator elements. This has been fixed in crossbeam-channel 0.4.4."}, {"lang": "es", "value": "Crossbeam es un conjunto de herramientas para programaci\u00f3n concurrente. En crossbeam-channel versiones anteriores a 0.4.4, el canal acotado asume inapropiadamente que \"Vec::from_iter\" ha asignado una capacidad igual a la cantidad de elementos iteradores. \"Vec::from_iter\" en realidad no garantiza eso y puede asignar memoria extra. El destructor del canal \"bounded\" reconstruye \"Vec\" a partir del puntero sin procesar bas\u00e1ndose en los supuestos incorrectos descritos anteriormente. Esto no es correcto y causa una desasignaci\u00f3n con la capacidad incorrecta cuando \"VVec::from_iter\" ha asignado diferentes tama\u00f1os con el n\u00famero de elementos del iterador. Esto ha sido corregido en crossbeam-channel versi\u00f3n 0.4.4"}], "lastModified": "2022-08-05T19:30:49.067", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:crossbeam_project:crossbeam:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "88240C4C-2AB0-4B8F-8CC8-371F77E60B96", "versionEndExcluding": "0.4.4"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
