CVE-2020-35886

An issue was discovered in the arr crate through 2020-08-25 for Rust. An attacker can smuggle non-Sync/Send types across a thread boundary to cause a data race...

RUSTSEC-2020-0143 Queues allow non-Send types to be sent to other threads, allowing data races

Affected versions of this crate unconditionally implemented Send for types used in queue implementations InnerSend, InnerRecv, FutInnerSend, FutInnerRecv. This allows users to send non-Send types to other threads, which can lead to data race bugs or other undefined behavior...

Queues allow non-Send types to be sent to other threads, allowing data races

Affected versions of this crate unconditionally implemented Send for types used in queue implementations InnerSend, InnerRecv, FutInnerSend, FutInnerRecv. This allows users to send non-Send types to other threads, which can lead to data race bugs or other undefined behavior. The flaw was correcte...

RUSTSEC-2020-0129 ShmWriter allows sending non-Send type across threads

Affected versions of this crate implement Send for ShmWriter without requiring H: Send. This allows users to send H: !Send to other threads, which can potentially lead to data races and undefined behavior...

RUSTSEC-2020-0098 UsbContext trait did not require implementers to be Send and Sync.

Affected versions of rusb did not require UsbContext to implement Send and Sync. However, through Device and DeviceHandle it is possible to use UsbContexts across threads. This issue allows non-thread safe UsbContext types to be used concurrently leading to data races and memory corruption. The...

RUSTSEC-2020-0152 ImmediateIO and TransactionalIO can cause data races

The ImmediateIO and TransactionalIO types implement Sync for all contained Expander types regardless of if the Expander itself is safe to use across threads. As the IO types allow retrieving the Expander, this can lead to non-thread safe types being sent across threads as part of the Expander...

SyncRef's clone() and debug() allow data races

Affected versions of this crate unconditionally implement Sync for SyncRef. This definition allows data races if &T is accessible through &SyncRef. SyncRef derives Clone and Debug, and the default implementations of those traits access &T by invoking T::clone & T::fmt. It is possible to create da...

ImmediateIO and TransactionalIO can cause data races

The ImmediateIO and TransactionalIO types implement Sync for all contained Expander types regardless of if the Expander itself is safe to use across threads. As the IO types allow retrieving the Expander, this can lead to non-thread safe types being sent across threads as part of the Expander...

ShmWriter allows sending non-Send type across threads

Affected versions of this crate implement Send for ShmWriter without requiring H: Send. This allows users to send H: !Send to other threads, which can potentially lead to data races and undefined behavior...

Multiple soundness issues in `Ptr`

Affected versions of this crate have the following issues: 1. Ptr implements Send and Sync for all types, this can lead to data races by sending non-thread safe types across threads. 2. Ptr::get violates mutable alias rules by returning multiple mutable references to the same object. 3. Ptr::writ...

Linux Kernel Heap Buffer Overflow DoS

The vulnerability of the domadvise function in the Linux operating system’s kernel is related to errors during the execution of multi-threaded tasks race conditions. Exploiting this vulnerability can allow an attacker to cause service failures...

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...

RUSTSEC-2020-0119 ReadTicket and WriteTicket should only be sendable when T is Send

Affected versions of this crate unconditionally implemented Send for ReadTicket & WriteTicket. This allows to send non-Send T to other threads. This can allows creating data races by cloning types with internal mutability and sending them to other threads as T of ReadTicket/WriteTicket. Such data...

Generators can cause data races if non-Send types are used in their generator functions

The Generator type is an iterable which uses a generator function that yields values. In affected versions of the crate, the provided function yielding values had no Send bounds despite the Generator itself implementing Send. The generator function lacking a Send bound means that types that are...

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...

AtomicBox<T> lacks bound on its Send and Sync traits allowing data races

AtomicBox is a Box type designed to be used across threads, however, it implements the Send and Sync traits for all types T. This allows non-Send types such as Rc and non-Sync types such as Cell to be used across thread boundaries which can trigger undefined behavior and memory corruption...

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...

QBot Trojan delivered via malspam campaign exploiting US election uncertainties

This blog post was authored by Jérôme Segura and Hossein Jazi. The 2020 US elections have been the subject of intense scrutiny and emotions, while happening in the middle of a global pandemic. As election night ended and uncertainty regarding the results began to creep in, threat actors decided t...
