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

The NSEC3 closest-encloser proof validation in hickory-proto'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 S...

X25519 secret validation did not check buffer length or clamping

The latest releases of the libcrux-ecdh crate contains the following bug-fix: 1301: Check length and clamping in X25519 secret validation. This is a breaking change since errors are now raised on unclamped X25519 secrets or inputs of the wrong length...

Unsound APIs of public `constant::Reader` and `StructSchema`

IdMap::from_iter may lead to uninitialized memory being freed on drop

Due to a flaw in the constructor idmap::IdMap::fromiter, ill-formed objects may be created in which the amount of actually initialized memory is less than what is expected by the fields of IdMap. Specifically, the field ids is initialized based on the capacity of the vector values, which is...

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...

Uninitialized read after allocating MemBump

The affected function, MemBump::new, would allocate memory without initializing it. Subsequently calling the created value's various alloc methods would then read and write the start of that memory as a Cell which is undefined behavior. Instead, it should zero initialize the start of the allocate...

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...

Use after free in `Parc` and `Prc` due to missing lifetime constraints

Affected versions of this crate didn't provide sufficient lifetime constraints to conversion functions from alloc::sync::Arc and alloc::rc::Rc, which made it possible to create projections of these reference counted pointers. Unlike the original reference counted pointers, these projections could...

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...

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

This crate attempted to typosquat the rand crate, and would link in a malware payload on macOS and Linux hosts when built. This advisory is to retrospectively document this attempted attack. The version information and download records of the malicious crate are no longer available. The related...

`root` appended to group listings

Affected versions append root to group listings, unless the correct listing has exactly 1024 groups. This affects both: - The supplementary groups of a user - The group access list of the current process If the caller uses this information for access control, this may lead to privilege escalation...

Undefined behaviour in `kvm_ioctls::ioctls::vm::VmFd::create_device`

An issue was identified in the VmFd::createdevice function, leading to undefined behavior and miscompilations on rustc 1.82.0 and newer due to the function's violation of Rust's pointer safety rules. The function downcasted a mutable reference to its struct kvmcreatedevice argument to an immutabl...

`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...

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...

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...

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...

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...

gitoxide-core does not neutralize special characters for terminals

Summary The gix and ein commands write pathnames and other metadata literally to terminals, even if they contain characters terminals treat specially, including ANSI escape sequences. This sometimes allows an untrusted repository to misrepresent its contents and to alter or concoct error messages...

Uncaught exception when transitioning the state of `AsyncGenerator` objects from within a property getter of `then`

The kstring integration in gix-attributes is unsound

gix-attributes in state::ValueRef unsafely creates a &str from a &u8 containing non-UTF8 data, with the justification that so long as nothing reads the &str and relies on it being UTF-8 in the &str, there is no UB: rust // SAFETY: our API makes accessing that value as str impossible, so illformed...

`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. It can be fixed by stubbing out the exposed op: javascript Deno.core.ops.oppanic = msg = throw new...

Usage of non-constant time base64 decoder could lead to leakage of secret key material

Versions before 0.7.0 of vodozemac use a non-constant time base64 implementation for importing key material for Megolm group sessions and PkDecryption Ed25519 secret keys. This flaw might allow an attacker to infer some information about the secret key material through a side-channel attack. Impa...

Dump Undefined Memory by `JitDumpFile`

The unsound function dumpcodeloadrecord uses fromrawparts to directly convert the pointer addr and len into a slice without any validation and that memory block would be dumped. Thus, the 'safe' function dumpcodeloadrecord is actually 'unsafe' since it requires the caller to guarantee that the ad...

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...

Traversal outside working tree enables arbitrary code execution
