`MsQueue` `push`/`pop` use the wrong orderings

Affected versions of this crate use orderings which are too weak to support this data structure. It is likely this has caused memory corruption in the wild:...

Delegate functions are missing `Send` bound

Affected versions of this crate did not require event handlers to have Send bound despite there being no guarantee of them being called on any particular thread, which can potentially lead to data races and undefined behavior. The flaw was corrected in commit afe3252 by adding Send bounds...

Aliased mutable references from `tls_rand` & `TlsWyRand`

TlsWyRand's implementation of Deref unconditionally dereferences a raw pointer, and returns multiple mutable references to the same object, which is undefined behavior...

`FixedSizeBinaryArray` does not perform bound checks on accessing values and offsets

FixedSizeBinaryArray performs insufficient bounds checks, which allows out-of-bounds reads in safe code...

`aesni` has been merged into the `aes` crate

Please use the aes crate going forward. The new repository location is at: AES-NI is now autodetected at runtime on i686/x86-64 platforms. If AES-NI is not present, the aes crate will fallback to a constant-time portable software implementation. To prevent this fallback and have absence of AES-NI...

AtomicBucket<T> unconditionally implements Send/Sync

In the affected versions of the crate, AtomicBucket unconditionally implements Send/Sync traits. Therefore, users can create a data race to the inner T: !Sync by using the AtomicBucket::datawith API. Such data races can potentially cause memory corruption or other undefined behavior. The flaw was...

nphysics3d is unmaintained

The maintainer has advised that this crate is passively-maintained and that it is being superseded by the Rapier project...

`mio` invalidly assumes the memory layout of std::net::SocketAddr

The mio crate has assumed std::net::SocketAddrV4 and std::net::SocketAddrV6 have the same memory layout as the system C representation sockaddr. It has simply casted the pointers to convert the socket addresses to the system representation. The standard library does not say anything about the...

crate has been renamed to `sn_fake_clock`

This crate has been renamed from fakeclock to snfakeclock. The new repository location is:...

dirs is unmaintained, use dirs-next instead

The dirs crate is not maintained any more; use dirs-next instead...

cosmian_kyber is unmaintained

cosmiankyber is a fork of Argyle-Software/kyber that has seen no maintainer activity. It inherits the fork parent's broken AVX2 constant-time code, and the open fix pull request Cosmian/kyber6 has gone unanswered. Recommended alternatives: - aws-lc-rs - graviola...

Out-of-bounds read when decoding CKA_ALLOWED_MECHANISMS

cryptoki treated the CKAALLOWEDMECHANISMS ulValueLen byte count as a CKMECHANISMTYPE element count. A valid nonempty attribute returned through the safe Session::getattributes API could cause construction of an out-of-bounds slice and undefined behavior. Possible consequences include a process...

`zbus_polkit`: authorization bypass via PID reuse

Subject::newforowner in the zbuspolkit crate encodes the uid entry of a unix-process polkit subject as an unsigned 32-bit integer D-Bus type u, whereas the org.freedesktop.PolicyKit1.Authority interface specifies a signed 32-bit integer D-Bus type i. Because of this type mismatch, polkit silently...

`sp-sized-chunks` is unmaintained

The sp-sized-chunks crate is a fork of sized-chunks. Its repository is archived and the crate is no longer maintained. Users should migrate to imbl-sized-chunks, a maintained fork...

`nostr-keyring` is unmaintained

The nostr-keyring crate is no longer actively maintained...

Relay authentication challenges can exhaust memory

The SDK forwarded every NIP-42 AUTH challenge received from a relay through an unbounded command queue. Challenge handling can wait for an asynchronous signer or user interaction, so receiving challenges was substantially faster than completing the corresponding authentication work. A malicious...

smallstr is unmaintained

The smallstr crate is unmaintained, and all versions are affected. Recommended alternatives: - compactstr is the most popular by far - smolstr focuses on immutable strings...

Incorrect Output of Incremental Portable SHAKE API on Multiple Squeeze Calls

The incremental squeeze functions in the portable SHAKE XOF API, when attempting to squeeze an output using multiple calls to squeeze, rather than squeezing the full output at once, could output incorrect values. Internally, output blocks that were not completely squeezed were not buffered for th...

Stubbed cryptography without warnings

The manzana crate appears to be a work-in-progress module for the Apple Silicon chips' features, including the Secure Enclave. This crate's description and READMEs make no hint at the fact that the SecureEnclaveSigner type is a stubbed implementation that does not actually perform any cryptograph...

`sha-rust` was removed from crates.io for malicious code

It appeared to be attempting to steal credentials from local files...

Underflow in aes_key_unwrap function

The aeskeyunwrap function would panic if passed a ciphertext that was too short. In a debug build, it would panic due to a subtraction underflow. In a release build, it would use the small negative quantity to allocate a vector. Since the allocator expects an unsigned quantity, the negative value...

crypto-hash crate is unmaintained

The crypto-hash crate is no longer actively maintained. If you rely on this crate, consider switching to a maintained alternative. Recommended alternatives - crypto-hashes...

custom_derive crate is unmaintained

The customderive crate is no longer actively maintained. If you rely on this crate, consider switching to a maintained alternative. Recommended alternatives - strum - macro-attr...

fxhash - no longer maintained

The fxhash crate is no longer maintained. The repository is stale and owner is no longer active on GitHub. Please take a look at rustc-hash instead...

Multiple memory corruption vulnerabilities in safe APIs

The crate has the following vulnerabilities: - The public trait arenavec::common::AllocHandle allows the return of raw pointers through its methods allocate and allocateorextend. However, the trait is not marked as unsafe, meaning users of the crate may implement it under the assumption that the...

`xcb::Connection::connect_to_fd*` functions violate I/O safety

The API of xcb::Connection has constructors which allow an arbitrary RawFd to be used as a socket connection. On either failure of these constructors or on the drop of Connection, it closes the associated file descriptor. Thus, a program which uses an OwnedFd such as a UnixStream as the file...

Host panic with `fd_renumber` WASIp1 function

This is an entry in the RustSec database for the Wasmtime security advisory located at https://github.com/bytecodealliance/wasmtime/security/advisories/GHSA-fm79-3f68-h2fc. For more information see the GitHub-hosted security advisory...

Malicious plugin names, recipients, or identities can cause arbitrary binary execution

A plugin name containing a path separator may allow an attacker to execute an arbitrary binary. Such a plugin name can be provided to the rage CLI through an attacker-controlled recipient or identity string, or an attacker-controlled plugin name via the -j flag. On UNIX systems, a directory...

Replaced by `pqcrypto-mlkem`

This crate has been replaced by pqcrypto-mlkem, which provides a FIPS203-compatible implementation of ML-KEM...

gix-path uses local config across repos when it is the highest scope

Summary gix-path executes git to find the path of a configuration file that belongs to the git installation itself, but mistakenly treats the local repository's configuration as system-wide if no higher scoped configuration is found. In rare cases, this causes a less trusted repository to be...

`cw0` is unmaintained

The crate cw0 was first renamed to utils in 2021 and then to cw-utils because utils was already claimed on crates.io. The crate cw0 is not maintained anymore since then and should be replaced with cw-utils...

`UserIdentity::is_verified` not checking verification status of own user identity while performing the check

The UserIdentity::isverified method in the matrix-sdk-crypto crate before version 0.7.2 doesn't take into account the verification status of the user's own identity while performing the check and may as a result return a value contrary to what is implied by its name and documentation. Impact If t...

op_panic in the base runtime can force a panic in the runtime's containing thread

Affected versions use denocore releases that expose Deno.core.ops.oppanic to the JS runtime in the base core This function when called triggers a manual panic in the thread containing the runtime, breaking sandboxing It can be fixed by stubbing out the exposed op: javascript Deno.core.ops.oppanic...

The maintainer of chrono-english is unresponsive

All versions will encounter compilation errors with a chrono version 0.4.35, due to backward incompatible API changes. User conradludgade reworked the original crate and created a fork with the same API surface called interim. The fork is better structured and passes the same test suite as...

Traversal outside working tree enables arbitrary code execution

Summary During checkout, gitoxide does not verify that paths point to locations in the working tree. A specially crafted repository can, when cloned, place new files anywhere writable by the application. Details Although gix-worktree-state checks for collisions with existing files, it does not...

Tor path lengths too short when "Vanguards lite" configured
