`owned-alloc` is unmaintained

The owned-alloc crate has had no release since 2018, and the maintainer has not responded to the upstream issue or to direct contact...

Double free / use-after-free in `Consumer::skip` and `Consumer::clear` when an element's `Drop` panics

Consumer::skip and Consumer::clear are not panic-safe. They drop the consumed elements in place and only afterwards call advancereadindex to move the ring buffer's read index past them. If an element's Drop panics mid-loop, advancereadindex is never reached, so the read index still points at the...

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...

Double free in `Map::into_iter` and an uninitialized `Arc` in `SharedIncin::clear`

Two independent soundness problems, both reachable from safe Rust. Map::intoiter drops builder the caller-supplied hasher H and incin by hand, then commits the ownership transfer with mem::forgetself. H::drop is user code and may panic. If it does, mem::forgetself is skipped and the still-live Ma...

FTP command injection via CRLF in control channel arguments

Affected versions of suppaftp wrote command arguments user name, password, paths, SITE arguments and custom commands to the FTP control channel without validation. An argument containing a carriage return \r or a line feed \n terminated the intended command line and let a second, attacker-chosen...

Out-of-bounds access in `get_disjoint_mut` due to incorrect bounds check

Impact The getdisjointmut method in slab v0.4.10 incorrectly checked if indices were within the slab's capacity instead of its length, allowing access to uninitialized memory. This could lead to undefined behavior or potential crashes. Patches This has been fixed in slab v0.4.11. Workarounds Avoi...

Denial of Service via malicious Web Push endpoint

Prior to version 0.10.3, the built-in clients of the web-push crate eagerly allocated memory based on the Content-Length header returned by the Web Push endpoint. Malicious Web Push endpoints could return a large Content-Length without ever having to send as much data, leading to denial of servic...

The author has archived the GitHub repository and mentions deprecation in project's README. Possible alternatives windows-registry...

Unsound usages of `core::slice::from_raw_parts_mut`

The library breaks the safety assumptions when using unsafe API slice::fromrawpartsmut. The pointer passed to fromrawpartsmut is misaligned by casting u8 to u16 raw pointer directly, which is unsound. The bug is patched by using alignoffset, which could make sure the memory address is aligned to ...

Unsound usages of `u8` type casting

The library provides a safe public API unpack to cast u8 array to arbitrary types, which can cause to undefined behaviors. The length check of array can only prevent out-of-bound access on the return type. However, it can't prevent misaligned pointer when casting u8 pointer to a type aligned to...

`idna` accepts Punycode labels that do not produce any non-ASCII when decoded

idna 0.5.0 and earlier accepts Punycode labels that do not produce any non-ASCII output, which means that either ASCII labels or the empty root label can be masked such that they appear unequal without IDNA processing or when processed with a different implementation and equal when processed with...

Build corruption when using `PYO3_CONFIG_FILE` environment variable

In PyO3 0.23.0 the PYO3CONFIGFILE environment variable used to configure builds regressed such that changing the environment variable would no longer trigger PyO3 to reconfigure and recompile. In combination with workflows using tools such as maturin to build for multiple versions in a single...

Bias of Polynomial Coefficients in Secret Sharing

Affected versions of this crate allowed for a bias when generating random polynomials for Shamir Secret Sharing, where instead of being within the range 0, 255 they were instead in the range 1, 255. A description from Cure53, who originally found the issue, is available: The correct method to...

Replaced by `pqcrypto-mlkem`

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

Risk of use-after-free in `borrowed` reads from Python weak references

The family of functions to read "borrowed" values from Python weak references were fundamentally unsound, because the weak reference does itself not have ownership of the value. At any point the last strong reference could be cleared and the borrowed value would become dangling. In PyO3 0.22.4...

webp crate may expose memory contents when encoding an image

Affected versions of this crate did not check that the input slice passed to "webp::Encoder::encode is large enough for the specified image dimensions. If the input slice is too short, the library will read out of bounds of the buffer and encode other memory contents as an image, resulting in...

gix-path improperly resolves configuration path reported by Git

Summary gix-path runs git to find the path of a configuration file associated with the git installation, but improperly resolves paths containing unusual or non-ASCII characters, in rare cases enabling a local attacker to inject configuration leading to code execution. Details In gixpath::env, th...

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,...

gix-path can use a fake program files location

Summary When looking for Git for Windows so it can run it to report its paths, gix-path can be tricked into running another git.exe placed in an untrusted location by a limited user account. Details Windows permits limited user accounts without administrative privileges to create new directories ...

Arithmetic overflows in cosmwasm-std

Some mathematical operations in cosmwasm-std use wrapping math instead of panicking on overflow for very big numbers. This can lead to wrong calculations in contracts that use these operations. Affected functions: - Uint256,512::pow / Int256,512::pow - Int256,512::neg Affected if overflow-checks ...

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...

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...

Improper Neutralization of CRLF Sequences in HTTP Headers ('HTTP Request/Response Splitting')

Summary Insufficient validation of outbound header values may lead to request splitting or response splitting attacks in scenarios where attackers have sufficient control over outbound headers. Details Outbound trilliumhttp::HeaderValue and trilliumhttp::HeaderName can be constructed infallibly a...

Plaintext exposed in decrypt_in_place_detached even on tag verification failure

Summary In the AES GCM implementation of decryptinplacedetached, the decrypted ciphertext i.e. the correct plaintext is exposed even if tag verification fails. Impact If a program using the aes-gcm crate's decryptinplace APIs accesses the buffer after decryption failure, it will contain a...

`openvpn-plugin-rs` was removed from crates.io for malicious code

This crate was part of a typosquatting malware cluster published by the user TerryDavisSoldier 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 longe...

Insufficient covariance check makes self_cell unsound

All public versions prior to 1.02 used an insufficient check to ensure that users correctly marked the dependent type as either covariant or notcovariant. This allowed users to mark a dependent as covariant even though its type was not covariant but invariant, for certain invariant types involvin...

`MaybeUninit` misuse in `simd-json-derive`

An invalid use of MaybeUninit::uninit.assumeinit in simd-json-derive's derive macro can cause undefined behavior. The original code used MaybeUninit to avoid initialisation of the struct and then set the fields using ptr::write. The undefined behavior triggered by this misuse of MaybeUninit can...

`fehler` is unmaintained; use `culpa` instead

The fehler crate is no longer maintained. Consider using culpa instead...

`oncecell` was removed from crates.io for malicious code

This crate was part of a typosquatting malware cluster published by the malicious user amaperf and contained a malware payload in build.rs to exfiltrate host information to the attacker. This advisory is to retrospectively document this attempted attack. The version information and download recor...

Mimalloc Can Allocate Memory with Bad Alignment

This crate depended on a promise regarding alignments made by the author of the mimalloc allocator to avoid using aligned allocation functions where possible for performance reasons. Since then, the mimalloc allocator's logic changed, making it break this promise. This caused this crate to return...

Data leakage between instances in the pooling allocator

Library exclusively intended to inject UB into safe Rust.

Quoting from the crate description: This crate is created purely to inject undefined behavior into stable, safe rust. Specifically, the inconceivable! macro is insta-UB if the ubinconceivable feature is enabled by any reverse dependency. The value this adds is questionable, and hides unsafe code...

cosmian_kyber: AVX2 backend skips Fujisaki-Okamoto implicit rejection, enabling chosen-ciphertext key recovery

Summary cosmiankyber is a fork of Argyle-Software/kyber and inherits a broken constant-time conditional-move routine cmov in its AVX2 backend. When built with the opt-in avx2 feature on x8664, cmov is a no-op: it never performs the copy. That cmov is the step that applies the Fujisaki-Okamoto FO...

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 ...

crossbeam-channel: double free on Drop

The internal Channel type's Drop method has a race which could, in some circumstances, lead to a double-free. This could result in memory corruption. Quoting from the upstream description in merge request \1187: The problem lies in the fact that dicardallmessages contained two paths that could le...

Unsound usages of `Vec::from_raw_parts`

The library provides a public safe API transmutevecasbytes, which incorrectly assumes that any generic type T could have stable layout, causing to uninitialized memory exposure if the users pass any types with padding bytes as T and cast it to u8 pointer. In the issue, we develop a PoC to show...

`ruzstd` uninit and out-of-bounds memory reads

Affected versions of ruzstd miscalculate the length of the allocated and init section of its internal RingBuffer, leading to uninitialized or out-of-bounds reads in copybytesovershooting of up to 15 bytes. This may result in up to 15 bytes of memory contents being written into the decoded data wh...

Denial of service because of stack overflow with malicious decompression input

A denial of service vulnerability was found in zlib-rs, triggered by specially constructed input. This input causes a stack overflow, resulting in the process using zlib-rs to crash. Impact Due to the way LLVM handles the zlib-rs codebase, tail calls were not guaranteed. This caused certain input...

Multiple soundness issues

fast-float contains multiple soundness issues: 1. Undefined behavior when checking input length, which has been merged but no package pubished. 1. Many functions marked as safe with non-local safety guarantees The library is also unmaintained. Alternatives For quickly parsing floating-point numbe...

Borsh serialization of HashMap is non-canonical

The borsh serialization of the HashMap did not follow the borsh specification. It potentially produced non-canonical encodings dependent on insertion order. It also did not perform canonicty checks on decoding. This can result in consensus splits and cause equivalent objects to be considered...

Runtime crash when combining tail calls with stack traces

This is an entry in the RustSec database for the Wasmtime security advisory located at https://github.com/bytecodealliance/wasmtime/security/advisories/GHSA-q8hx-mm92-4wvg. For more information see the GitHub-hosted security advisory...

Segmentation fault due to use of uninitialized memory

When trying to decompress a file using "ouch", we can reach the function "ouch::archive::zip::convertzipdatetime". In the function, there is a unsafe function, "transmute". Once the "transmute" function is called to convert the type of "month" object, the address of the object is changed to the...

Memory leak when calling a canister method via `ic_cdk::call`

When a canister method is called via iccdk::call, a new Future CallFuture is created and can be awaited by the caller to get the execution result. Internally, the state of the Future is tracked and stored in a struct called CallFutureState. A bug in the polling implementation of the CallFuture...

`MemBio::get_buf` has undefined behavior with empty buffers

Previously, MemBio::getbuf called slice::fromrawparts with a null-pointer, which violates the functions invariants, leading to undefined behavior. In debug builds this would produce an assertion failure. This is now fixed...

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...

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...

BTreeMap memory leak when deallocating nodes with overflows

When storing unbounded types in a BTreeMap, a node is represented as a linked list of "memory chunks". In some cases, when we deallocate a node only the first memory chunk is deallocated, and the rest of the memory chunks remain incorrectly allocated, causing a memory leak. In the worst case,...
