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...

Denial of service in Quinn endpoints

Receiving QUIC transport parameters containing invalid values could lead to a panic. Unfortunately the maintainers did not properly assess usage of unwrap calls in the transport parameters parsing code, and we did not have sufficient fuzzing coverage to find this issue. We have since added a...

`time-sync` was removed from crates.io due to malicious code

The time-sync crate attempted to exfiltrate .env files to a server that was in turn impersonating the legitimate timeapi.io service. This the same attack that we've seen three times in the last few days. The malicious crate had 1 version published on 2026-03-04 approximately 50 minutes before...

Panic in `libcrux-psq` on decryption of malformed AES-GCM ciphertext

The latest releases of the libcrux-psq crate contains the following bug-fix: 1319: Propagate AEADError instead of panicking The issue fixed in 1319 was first reported by Nadim Kobeissi...

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

This crate was used as a dependency by finchclirust and finch-rst and contained a malware payload to exfiltrate credentials. The malicious crate had 1 version published on 2025-12-08 and had been downloaded 22 times. Other than the other crates above that were part of the attack, no other crates...

Incorrect calculation on aarch64

On platforms without the core::arch::aarch64::vxarqu64 intrinsic, an unverified fallback in libcrux-intrinsics v0.0.3 passed incorrect arguments and produced wrong results. This corrupted SHA-3 digests and caused libcrux-ml-kem and libcrux-ml-dsa to sample incorrectly, yielding incorrect shared...

Use-After-Free in `Md::fetch` and `Cipher::fetch`

When a Some... value was passed to the properties argument of either of these functions, a use-after-free would result. In practice this would nearly always result in OpenSSL treating the properties as an empty string due to CString::drop's behavior. The maintainers thank quitbug for reporting th...

humantime is unmaintained

Latest humantime crates.io release is four years old and GitHub repository has not seen commits in four years. Question about maintenance status has not gotten any reaction from maintainer: https://github.com/tailhook/humantime/issues/31 Update: maintained again The maintainer has responded and...

`lfest-main` was removed from crates.io for malicious code

This crate was part of a typosquatting malware cluster published by the user Kraded 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 available...

`users` crate is unmaintained

The users crate hasn't seen any action since 2020-10-08. The developer seems MIA since. Recommended alternatives - uzers - sysinfo MIA: https://github.com/ogham/rust-users/issues/54 uzers: https://crates.io/crates/uzers sysinfo: https://crates.io/crates/sysinfo...

NULL pointer dereference in `stb_image`

A bug in error handling in the stbimage C library could cause a NULL pointer dereference when attempting to load an invalid or unsupported image file. This is fixed in version 0.2.5 and later of the stbimage Rust crate, by patching the C code to correctly handle NULL pointers. Thank you to GitHub...

Gitoxide has renamed its crates.

All crates in the gitoxide project have been renamed from git- to gix-. The git- prefixed crates are no longer being updated. Switch to using gix-hash to continue receiving updates...

Out-of-bounds read when opening multiple column families with TTL

Affected versions of this crate called the RocksDB C API rocksdbopencolumnfamilieswithttl with a pointer to a single integer TTL value, but one TTL value for each column family is expected. This is only relevant when using rocksdb::DBWithThreadMode::opencfdescriptorswithttl with multiple column...

`rmp-serde` `Raw` and `RawRef` unsound

It was found that Raw::fromutf8 expects valid UTF-8. If invalid UTF-8 is received it can cause the process to crash...

Panic on incorrect date input to `simple_asn1`

Version 0.6.0 of the simpleasn1 crate panics on certain malformed inputs to its parsing functions, including fromder and derdecode. Because this crate is frequently used with inputs from the network, this should be considered a security vulnerability. The issue occurs when parsing the old ASN.1...

Miscomputed results when using AVX2 backend

The v0.9.7 release of the sha2 crate introduced a new AVX2-accelerated backend which was automatically enabled for all x86/x8664 CPUs where AVX2 support was autodetected at runtime. This backend was buggy and would miscompute results for long messages i.e. messages spanning multiple SHA blocks. T...

`better-macro` has deliberate RCE to prove a point

better-macro is a fake crate which is "Proving A Point" that proc-macros can run arbitrary code. This is not a particularly novel or interesting observation. It currently opens https://github.com/raycar5/better-macro/blob/master/doc/hi.md which doesn't appear to have any malicious content, but...

git-delta before 0.8.3 on Windows resolves an executable's pathname as a relative path from the current directory...

Permissions bypass in pleaser

pleaseedit in pleaser before 0.4 uses predictable temporary filenames in /tmp and the target directory. This allows a local attacker to gain full root privileges by staging a symlink attack...

crate has been renamed to `qjsonrpc`

This crate has been renamed from jsonrpc-quic to qjsonrpc. The new repository location is:...

Multiple Transfer-Encoding headers misinterprets request payload

hyper's HTTP server code had a flaw that incorrectly understands some requests with multiple transfer-encoding headers to have a chunked payload, when it should have been rejected as illegal. This combined with an upstream HTTP proxy that understands the request payload boundary differently can...

insert_slice_clone can double drop if Clone panics.

Affected versions of this crate used ptr::copy when inserting into the middle of a Vec. When ownership was temporarily duplicated during this copy, it calls the clone method of a user provided element. This issue can result in an element being double-freed if the clone call panics. Commit 20cb73d...

'Read' on uninitialized memory may cause UB

Affected versions of this crate passes an uninitialized buffer to a user-provided Read implementation. The crate currently contains 4 occurrences of such cases. Arbitrary Read implementations can read from the uninitialized buffer memory exposure and also can return incorrect number of bytes...

RingBuffer can create multiple mutable references and cause data races

The RingBuffer type retrieves mutable references from the DataProvider in a non-atomic manner, potentially allowing the creation of multiple mutable references. RingBuffer also implements the Send and Sync traits for all types T. This allows undefined behavior from the aliased mutable references ...

ArcGuard's Send and Sync should have bounds on RC

Affected versions of this crate implement Send/Sync for ArcGuard with no trait bounds on RC. This allows users to send RC: !Send to other threads and also allows users to concurrently access Rc: !Sync from multiple threads. This can result in memory corruption from data race or other undefined...

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...

LateStatic has incorrect Sync bound

Affected versions of this crate implemented Sync for LateStatic with T: Send, so that it is possible to create a data race to a type T: Send + !Sync e.g. Cell. This can result in a memory corruption or other kinds of undefined behavior. The flaw was corrected in commit 11f396c by replacing the T:...

Memory safety issues in `compact::Vec`

compact::Vec contains multiple memory safety issues. 1. It mishandles large capacity and causes out-of-bound access in 32-bit / allocator layout mismatch in 64-bit. 2. remove is not panic-safe and causes double-free when an index larger than the length is provided...

Improper uniqueness verification of signature threshold

The tough library, prior to 0.7.1, does not properly verify the uniqueness of keys in the signatures provided to meet the threshold of cryptographic signatures. It allows someone with access to a valid signing key to create multiple valid signatures in order to circumvent TUF requiring a minimum...

crust repo has been archived; use libp2p instead

The crust crate repo was archived with no warning or explanation. Given that it was archived with no warning or successor, there's not an official replacement but rust-libp2p looks like it's got a similar feature set and is actively maintained...

Use-after-free in buffer conversion implementation

The From implementation for Vec was not properly implemented, returning a vector backed by freed memory. This could lead to memory corruption or be exploited to cause undefined behavior. A fix was published in version 0.1.3...

Flaw in generativity allows out-of-bounds access

Affected versions of this crate did not properly implement the generativity, because the invariant lifetimes were not necessarily dropped. This allows an attacker to mix up two arenas, using indices created from one arena with another one. This might lead to an out-of-bounds read or write access...

smallvec creates uninitialized value of any type

Affected versions of this crate called mem::uninitialized to create values of a user-supplied type T. This is unsound e.g. if T is a reference type which must be non-null and thus may not remain uninitialized. The flaw was corrected by avoiding the use of mem::uninitialized, using MaybeUninit...

An integer underflow could lead to panic

A mistake in error handling in untrusted before 0.6.2 could lead to an integer underflow and panic if a user of the crate didn't properly check for errors returned by untrusted. Combination of these two programming errors one in untrusted and another by user of this crate could lead to a panic an...

`cassandra` crate is unmaintained; use `cassandra-cpp` instead

The cassandra crate has not seen a release since December 2016, and its author is unresponsive. The cassandra-cpp crate is a maintained fork: https://github.com/Metaswitch/cassandra-rs...

Panic-safety unsoundness in `SplitVec::extend_from_slice` (uninitialized read)

SplitVec::extendfromslice increments the logical length self.len before cloning the incoming elements into the reserved slots. If an element's Clone panics mid-fill, unwinding leaves self.len counting slots that were never initialized. A later safe read get, indexing, iter then reads one of those...

A `BigInt` division panics, and two neighbouring operations answer wrongly in silence

viperjs is a JavaScript engine intended to run untrusted script inside a host application, so script text is data rather than a trusted caller and a panic reachable from script is a denial of service in the embedder's process. A divisor whose magnitude lands exactly on the engine's internal limb...

`Program<System>` accepts arbitrary executable programs

Affected versions of anchor-lang did not properly validate accounts declared as Program. The generic Program validation path used Pubkey::default as a sentinel to decide whether any executable program should be accepted. Since the system program id is also the default pubkey, Program was treated...

Fragile bounds check when sampling from image

A read of pixels was coded as modifying coordinates to lie within the image bounds. It would calculate a coordinate by adding a constant to an input and taking the minimum of the resulting coordinate and 'dimension - 1'. This would not protect against malicious inputs that could overflow the...

NSEC3 closest-encloser proof validation enters unbounded loop on cross-zone responses

The NSEC3 closest-encloser proof validation in hickory-net's DnssecDnsHandle walks from the QNAME up to the SOA owner name, building a list of candidate encloser names. The iterator used assumes the QNAME is a descendant of the SOA owner, terminating only when the current candidate equals the SOA...

PAX Header Desynchronization in astral-tokio-tar

Versions of astral-tokio-tar prior to 0.6.1 contain a PAX header interpretation bug that allows manipulated entries to be made selectively visible or invisible during extraction with astral-tokio-tar versus other tar implementations. An attacker could use this differential to smuggle unexpected...

Miscompiled guest heap access enables sandbox escape on aarch64 Cranelift

CRLs not considered authoritative by Distribution Point due to faulty matching logic

If a certificate had more than one distributionPoint, then only the first distributionPoint would be considered against each CRL's IssuingDistributionPoint distributionPoint, and then the certificate's subsequent distributionPoints would be ignored. The impact was that correctly provided CRLs wou...
