CRL Distribution Point Scope Check Logic Error in AWS-LC

A logic error in CRL distribution point matching in AWS-LC allows a revoked certificate to bypass revocation checks during certificate validation, when the application enables CRL checking and uses partitioned CRLs with Issuing Distribution Point IDP extensions. Customers of AWS services do not...

All-Zero Key Generation on Catastrophic RNG Failure

The libcrux-ed25519 key generation samples Ed25519 secret keys from a provided CSPRNG in a loop for up to 100 attempts until a non-zero key is found. If a non-zero key could not be sampled within 100 attempts the key generation function would silently continue with an all-zero buffer as the secre...

Incorrect Check of Signer Response Norm During Verification

The ML-DSA verification algorithm as specified in FIPS 204, subsection 6.3 requires verifiers to check that the infinity norm of the deserialized signer response $z$ does not exceed $\gamma1 - \beta$ line 13 of Algorithm 8. The same check is required to be performed during signature generation...

Non-constant-time code generation on ARM32 targets

Summary While the cmov crate has a special backend for aarch64 which uses special CSEL instructions, on 32-bit ARM it uses a portable pure Rust fallback implementation. This implementation uses a combination of bitwise arithmetic and core::hint::blackbox to attempt to coerce constant-time code...

matrix-sdk-base: Denial of service due to custom `m.room.join_rules` events

The matrix-sdk-base crate is unable to handle responses that include custom m.room.joinrules values due to a serialization bug. This can be exploited to cause a denial-of-service condition, if a user is invited to a room with non-standard join rules, the crate's sync process will stall, preventin...

CGGMP21 presignatures can be used in the way that significantly reduces security

This attack is against presignatures used in very specific context: Presignatures + HD wallets derivation: security level reduces to 85 bits \ Previously you could generate a presignature, and then choose a HD derivation path while issuing a partial signature via Presignature::setderivationpath,...

Uninitialized memory exposure in create_ring_buffer

The safe function createringbuffer allocates a buffer using Vec::withcapacity followed by setlen, creating a Box containing uninitialized memory. This leads to undefined behavior when functions like writeslices create typed slices e.g., &mut bool over the uninitialized memory, violating Rust's...

Uninitialized memory exposure in string reading functions

Multiple string reading functions expose uninitialized memory by setting length to capacity when no null terminator is found. This allows reading uninitialized memory which may contain sensitive data from previous allocations. The ncurses-rs repository is archived and unmaintained...

Heap-buffer-overflow in nftnl::Batch::with_page_size (nftnl-rs)

A heap-buffer-overflow vulnerability exists in the Rust wrapper for libnftnl, triggered via the nftnl::Batch::withpagesize constructor. When a small or malformed page size is provided, the underlying C code allocates an insufficient buffer, leading to out-of-bounds writes during batch...

matrix-sdk-crypto vulnerable to encrypted event sender spoofing by homeserver administrator

matrix-sdk-crypto versions 0.8.0 up to and including 0.11.0 does not correctly validate the sender of an encrypted event. Accordingly, a malicious homeserver operator can modify events served to clients, making those events appear to the recipient as if they were sent by another user. Although th...

Heap Buffer Overflow in the DrainCol Destructor

An off-by-one error in the DrainCol::drop destructor could cause an unsafe memory copy operation to exceed the bounds of the associated vector. The error was related to the size of the data being copied in one of the ptr::copy invocations inside the destructor. When removing the first column from...

`DTriangle` accessors may read out of bounds in affected versions

In affected versions, DTriangle::neighborbyorder and DTriangle::vertexbyorder were public safe functions that accepted an arbitrary order value. These functions used order to access fixed-size internal arrays with getunchecked, without checking whether order was within bounds. Calling these metho...

`Endpoint::retry()` calls can lead to panicking

In 0.11.0, we overhauled the server-side Endpoint implementation to enable more careful handling of incoming connection attempts. However, some of the code paths that cleaned up state after connection attempts were processed confused the initial destination connection ID with the destination...

The maintainer of chrono-english is unresponsive

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...

Invalid pointer dereference in `fmt::Pointer` impl for `Atomic` and `Shared` when the underlying pointer is invalid

Affected versions of fmt::Display dereference the underlying pointer. This causes a invalid pointer dereference e.g., when a pointer created with Atomic::null or Shared::null. fmt::Debug impls and pre-0.9 fmt::Display impls, which do not dereference pointers, are not affected by this issue...
