VCID-br15-895f-aaap
|
An issue was discovered in the crossbeam-channel crate before 0.4.4 for Rust. It has incorrect expectations about the relationship between the memory allocation and how many iterator elements there are.

VCID-nxf6-b31u-aaac

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.
