Affected versions of this crate unconditionally implemented
Send&Syncfor typesPinSlab<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>orUnordered<T, S>and accessed concurrently from multiple threads.The flaw was corrected in commits 92f40b4 & 6a6c367 by adding trait bound
T: SendtoSendimpls forPinSlab<T>&Unordered<T, S>and addingT: SynctoSyncimpls forPinSlab<T>&Unordered<T, S>. - Database specific
