CVE-2020-15254
Mozilla: Undefined behavior in bounded channel of crossbeam rust crate
Severidad por fuente
La etiqueta propia de Trivy es CRITICAL. Crítica según NVD. Más baja según GHSA (alta), Red Hat (alta), Ubuntu (media).
Descripción
Crossbeam is a set of tools for concurrent programming. 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.
