RUSTSEC-2024-0375 `atty` is unmaintained

The maintainer of atty has published an official notice that the crate is no longer under development, and that users should instead rely on the functionality in the standard library's IsTerminal trait. Alternatives - std::io::IsTerminal - Stable since Rust 1.70.0 and the recommended replacement...

RUSTSEC-2024-0362 Stack overflow when parsing specially crafted JSON ABI strings

Affected versions of the alloy-json-abi crate did not properly handle parsing of malformatted JSON ABI strings. The JsonAbi::parse method can be tricked into a stack overflow when processing specially crafted input. This stack overflow can lead to a crash of the application using this crate,...

RUSTSEC-2024-0346 Incorrect usage of `#[repr(packed)]`

The affected versions make unsafe memory accesses under the assumption that reprpacked has a guaranteed field order. The Rust specification does not guarantee this, and https://github.com/rust-lang/rust/pull/125360 1.80.0-beta starts reordering fields of reprpacked structs, leading to illegal...

RUSTSEC-2024-0352 Refs and paths with reserved Windows device names access the devices

Summary On Windows, fetching refs that clash with legacy device names reads from the devices, and checking out paths that clash with such names writes arbitrary data to the devices. This allows a repository, when cloned, to cause indefinite blocking or the production of arbitrary message that...

RUSTSEC-2024-0019 Tokens for named pipes may be delivered after deregistration

Impact When using named pipes on Windows, mio will under some circumstances return invalid tokens that correspond to named pipes that have already been deregistered from the mio registry. The impact of this vulnerability depends on how mio is used. For some applications, invalid tokens may be...

RUSTSEC-2024-0418 gtk-rs GTK3 bindings - no longer maintained

Please take a look at gtk4-rs instead. Update The gtk-rs repository was unarchived and the README...

RUSTSEC-2024-0018 ObjectPool creates uninitialized memory when freeing objects

As of version 0.6.0, the ObjectPool explicitly creates an uninitialized instance of its type parameter when it attempts to free an object, and swaps it into the storage. This causes instant undefined behavior due to reading the uninitialized memory in order to write it to the pool storage...

RUSTSEC-2024-0005 Unsound sending of non-Send types across threads

Affected versions can run the Drop impl of a non-Send type on a different thread than it was created on. The flaw occurs when a stderr write performed by the threadalone crate fails, for example because stderr is redirected to a location on a filesystem that is full, or because stderr is a pipe...

RUSTSEC-2023-0124 `bit-flags` was removed from crates.io for malicious code

This crate was part of a typosquatting malware cluster published by the user alexrichton to run an arbitrary malware payload on Windows hosts. This advisory is to retrospectively document this attempted attack. The version information and download records of the malicious crate are no longer...

The cpython crate and the underlying python3-sys and python27-sys crates have been marked as no longer actively maintained by the developer. There are also open issues for unsound code that is currently in these crates: - cpython265: Using some string functions causes segmentation faults on...

RUSTSEC-2023-0077 Remotely exploitable DoS condition in Rosenpass <=0.2.0

Affected version do this crate did not validate the size of buffers when attempting to decode messages. This allows an attacker to trigger a panic by sending a UDP datagram with a 1 byte payload over network. This flaw was corrected by validating the size of the buffers before attempting to decod...

RUSTSEC-2023-0055 Multiple soundness issues

lexical contains multiple soundness issues: 1. Bytes::read allows creating instances of types with invalid bit patterns 1. BytesIter::read advances iterators out of bounds 1.

The tui crate is no longer maintained. Consider using the ratatui crate instead...

RUSTSEC-2023-0035 Adverserial use of `make_bitflags!` macro can cause undefined behavior

The macro relied on an expression of the form Enum::Variant always being a variant of the enum. However, it may also be an associated integer constant, in which case there's no guarantee that the value of said constant consists only of bits valid for this bitflag type. Thus, code like this could...

RUSTSEC-2023-0032 Unsound FFI: Wrong API usage causes write past allocated area

The following usage causes undefined behavior. rust let kp: ntru::types::KeyPair = …; kp.getpublic.exportDefault::default When compiled with debug assertions, the code above will trigger a attempt to subtract with overflow panic before UB occurs. Other mistakes e.g. using EncParams from a differe...

Ward Beullens found a practical key-recovery attack against Rainbow. The level I parametersets are removed from liboqs starting from version 0.7.2. Find the scientific details in Breaking Rainbow Takes a Weekend on a Laptop. This means all the oqs::sig::Algorithm::RainbowI variants are insecure...

RUSTSEC-2022-0078 Use-after-free due to a lifetime error in `Vec::into_iter()`

In affected versions of this crate, the lifetime of the iterator produced by Vec::intoiter is not constrained to the lifetime of the Bump that allocated the vector's memory. Using the iterator after the Bump is dropped causes use-after-free accesses. The following example demonstrates memory...

RUSTSEC-2021-0138 Incorrect use of `set_len` allows for un-initialized memory

Affected versions of this crate passes an uninitialized buffer to a user-provided Read implementation. Arbitrary Read implementations can read from the uninitialized buffer memory exposure and also can return incorrect number of bytes written to the buffer. Reading from uninitialized memory...

RUSTSEC-2021-0072 Task dropped in wrong thread when aborting `LocalSet` task

When aborting a task with JoinHandle::abort, the future is dropped in the thread calling abort if the task is not currently being executed. This is incorrect for tasks spawned on a LocalSet. This can easily result in race conditions as many projects use Rc or RefCell in their Tokio tasks for bett...

RUSTSEC-2021-0145 Potential unaligned read

On windows, atty dereferences a potentially unaligned pointer. In practice however, the pointer won't be unaligned unless a custom global allocator is used. In particular, the System allocator on windows uses HeapAlloc, which guarantees a large enough alignment. atty is Unmaintained A Pull Reques...

RUSTSEC-2026-0275 Legacy `azure_core` writes the `authorization` header value to logs

Applications built on the legacy Azure SDK for Rust azurecore 0.21.0 and earlier write the value of the outgoing authorization header to their logs whenever debug-level logging is enabled, and in every affected version also at trace level. The leaked values are live credentials — Microsoft Entra ...

RUSTSEC-2026-0254 Panic-safety unsoundness in `Chunk` and `InlineArray` (use-after-free / double-free)

Several methods in sp-sized-chunks drop elements before updating the container's length/boundary metadata. If an element's Drop panics during the drop, the metadata update is skipped, so the container still treats the already-dropped elements as live. When the container is later dropped, its own...

RUSTSEC-2026-0138 Unsound access to padding bytes while serializing date/time values using the Mysql backend

Diesel-async uses the mysql-async crate for interacting with Mysql compatible databases. This library already provides access to deserialized data for date/time releated types. Diesel-async then translated these deserialized data back to their serialized binary representation to hook into diesels...

RUSTSEC-2026-0109 Broken hard revocation handling

Before sq-git checks if a commit can be authenticated, it first looks for hard revocations. Because parsing a policy is expensive and a project's policy rarely changes, sq-git has an optimization to only check a policy if it hasn't checked it before. It does this by maintaining a set of policies...

RUSTSEC-2026-0044 AWS-LC X.509 Name Constraints Bypass via Wildcard/Unicode CN

RUSTSEC-2026-0067 `unpack_in` can chmod arbitrary directories by following symlinks

In versions 0.4.44 and below of tar-rs, when unpacking a tar archive, the tar crate's unpackdir function uses fs::metadatafs-metadata to check whether a path that already exists is a directory. Because fs::metadata follows symbolic links, a crafted tarball containing a symlink entry followed by a...
