8.1 (High) CVSS_V3 - CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H CVSS Calculator

Summary

PinSlab<T> and Unordered<T, S> need bounds on their Send/Sync traits

Details

Affected versions of this crate unconditionally implemented Send & Sync for types PinSlab<T> & Unordered<T, S>. This allows sending non-Send types to other threads and concurrently accessing non-Sync types from multiple threads.

This can result in a data race & memory corruption when types that provide internal mutability without synchronization are contained within PinSlab<T> or Unordered<T, S> and accessed concurrently from multiple threads.

The flaw was corrected in commits 92f40b4 & 6a6c367 by adding trait bound T: Send to Send impls for PinSlab<T> & Unordered<T, S> and adding T: Sync to Sync impls for PinSlab<T> & Unordered<T, S>.
