CVE-2020-15254 (GCVE-0-2020-15254)

Vulnerability from cvelistv5 – Published: 2020-10-16 17:05 – Updated: 2024-08-04 13:08

Title

Undefined Behavior in bounded Crossbeam channel

Summary

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.

Severity

8.1 (High)
