RUSTSEC-2020-0135 Slock<T> allows sending non-Send types across thread boundaries

Slock unconditionally implements Send/Sync. Affected versions of this crate allows sending non-Send types to other threads, which can lead to data races and memory corruption due to the data race...

TryMutex<T> allows sending non-Send type across threads

Affected versions of this crate unconditionally implemented Sync trait for TryMutex type. This allows users to put non-Send T type in TryMutex and send it to another thread, which can cause a data race. The flaw was corrected in the 0.3.0 release by adding T: Send bound for the Sync trait...

RUSTSEC-2020-0087 TryMutex<T> allows sending non-Send type across threads

Affected versions of this crate unconditionally implemented Sync trait for TryMutex type. This allows users to put non-Send T type in TryMutex and send it to another thread, which can cause a data race. The flaw was corrected in the 0.3.0 release by adding T: Send bound for the Sync trait...

Singleton lacks bounds on Send and Sync.

Singleton is meant to be a static object that can be initialized lazily. In order to satisfy the requirement that static items must implement Sync, Singleton implemented both Sync and Send unconditionally. This allows for a bug where non-Sync types such as Cell can be used in singletons and cause...

RUSTSEC-2020-0116 PinSlab<T> and Unordered<T, S> need bounds on their Send/Sync traits

Affected versions of this crate unconditionally implemented Send & Sync for types PinSlab & Unordered. 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...

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

Affected versions of this crate unconditionally implemented Send & Sync for types PinSlab & Unordered. 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...

Data race and memory safety issue in `Index`

The appendix crate implements a key-value mapping data structure called Index that is stored on disk. The crate allows for any type to inhabit the generic K and V type parameters and implements Send and Sync for them unconditionally. Using a type that is not marked as Send or Sync with Index can...

Queue<T> should have a Send bound on its Send/Sync traits

Affected versions of this crate unconditionally implements Send/Sync for Queue. This allows 1 creating data races to a T: !Sync and 2 sending T: !Send to other threads, resulting in memory corruption or other undefined behavior...

SyncChannel<T> can move 'T: !Send' to other threads

Affected versions of this crate unconditionally implement Send/Sync for SyncChannel. SyncChannel doesn't provide access to &T but merely serves as a channel that consumes and returns owned T. Users can create UB in safe Rust by sending T: !Send to other threads with SyncChannel::send/recv APIs...

RUSTSEC-2020-0133 Queue<T> should have a Send bound on its Send/Sync traits

Affected versions of this crate unconditionally implements Send/Sync for Queue. This allows 1 creating data races to a T: !Sync and 2 sending T: !Send to other threads, resulting in memory corruption or other undefined behavior...

RUSTSEC-2020-0126 SyncChannel<T> can move 'T: !Send' to other threads

Affected versions of this crate unconditionally implement Send/Sync for SyncChannel. SyncChannel doesn't provide access to &T but merely serves as a channel that consumes and returns owned T. Users can create UB in safe Rust by sending T: !Send to other threads with SyncChannel::send/recv APIs...

RUSTSEC-2020-0134 `LockWeak<T>` allows to create data race to `T`.

In the affected versions of this crate, LockWeak unconditionally implemented Send with no trait bounds on T. LockWeak doesn't own T and only provides &T. This allows concurrent access to a non-Sync T, which can cause undefined behavior like data races...

`LockWeak<T>` allows to create data race to `T`.

In the affected versions of this crate, LockWeak unconditionally implemented Send with no trait bounds on T. LockWeak doesn't own T and only provides &T. This allows concurrent access to a non-Sync T, which can cause undefined behavior like data races...

Send/Sync bound needed on V in `impl Send/Sync for ARCache<K, V>`

Affected versions of this crate unconditionally implemented Send/Sync traits for ARCache type. This allows users to send/access types that do not implement Send/Sync, which can cause a data race. The flaw was corrected in the 0.2.6 release by adding bounds K: Send + Sync & V: Send + Sync to...

Bunch<T> unconditionally implements Send/Sync

Affected versions of this crate unconditionally implements Send/Sync for Bunch. This allows users to insert T: !Sync to Bunch. It is possible to create a data race to a T: !Sync by invoking the Bunch::get API which returns &T from multiple threads. It is also possible to send T: !Send to other...

RUSTSEC-2020-0130 Bunch<T> unconditionally implements Send/Sync

Affected versions of this crate unconditionally implements Send/Sync for Bunch. This allows users to insert T: !Sync to Bunch. It is possible to create a data race to a T: !Sync by invoking the Bunch::get API which returns &T from multiple threads. It is also possible to send T: !Send to other...

Denial Of Service (DoS)

cbor-sync is vulnerable to Denial Of Service. A Denial Of Service condition occurs when the server drains all the free memory during allocation of an unbounded length buffer...

RUSTSEC-2020-0107 hashconsing's HConsed lacks Send/Sync bound for its Send/Sync trait.

Affected versions of hashconsing implements Send/Sync for its HConsed type without restricting it to Sendable types and Syncable types. This allows non-Sync types such as Cell to be shared across threads leading to undefined behavior and memory corruption in concurrent programs...

AtomicBox<T> implements Send/Sync for any `T: Sized`

Affected versions of this crate implements Send/Sync for AtomicBox without requiring T: Send/T: Sync. This allows to create data races to T: !Sync and send T: !Send to another thread. Such behavior breaks the compile-time thread safety guarantees of Rust, and allows users to incur undefined...
