The affected version of this crate’s 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.
We recommend users to upgrade to 0.4.4.
See https://github.com/crossbeam-rs/crossbeam/pull/533, https://github.com/crossbeam-rs/crossbeam/issues/539, and https://github.com/RustSec/advisory-db/pull/425 for more details.
