Empty NIP-50 search filters can panic

The NIP-50 event-matching path searched event content with slice::windowssearch.len. An empty search string therefore called slice::windows0, which always panics instead of returning a match result. A remote client able to submit filters to an application using this matcher could trigger the pani...

Uint shift operations: incorrect overflow flags and truncated shift amounts

Uint::overflowingshl/overflowingshr returned false-negative overflow flags. overflowingshl missed bits shifted above BITS but within the top limb non-limb-aligned widths such as U160, and limbs wholly discarded by shifts = 64; overflowingshr missed wholly discarded low limbs. Shifted values were...

Non-painting replaced elements amplify to thousands of blank PDF pages (denial of service)

fulgur converts untrusted HTML/CSS into PDF, commonly on a server that processes input supplied by many tenants. In versions prior to 0.26.0, a childless box that resolves to a pathologically tall height was amplified into thousands of blank PDF pages, even when it produces no visible output. The...

Timing Side-Channel in AES-CCM Tag Verification in AWS-LC

Observable timing discrepancy in AES-CCM decryption in AWS-LC allows an unauthenticated user to potentially determine authentication tag validity via timing analysis. The impacted implementations are through the EVP CIPHER API: EVPaes128ccm, EVPaes192ccm, and EVPaes256ccm. Customers of AWS servic...

`Bitmap::try_from(&[u8])` can create invalid values

The TryFrom implementation for Bitmap copies the input bytes into an uninitialized backing store and calls assumeinit without validating that the bytes form a valid value of the backing store type. For SIZE = 1 the backing store is a bool, so any input byte other than 0x00 or 0x01 produces an...

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,...

`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...

`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...

CWA-2023-004: Excessive number of function parameters in compiled Wasm

Unauthenticated Nonce Increment in snow

There was a logic bug where unauthenticated payloads could still cause a nonce increment in snow's internal state. For an attacker with privileges to inject packets into the channel over which the Noise session operates, this could allow a denial-of-service attack which could prevent message...

Multiple issues involving quote API

Issue 1: Failure to quote characters Affected versions of this crate allowed the bytes and \xa0 to appear unquoted and unescaped in command arguments. If the output of quote or join is passed to a shell, then what should be a single command argument could be interpreted as multiple arguments. Thi...

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...

Panic-safety unsoundness in `Chunk`, `RingBuffer`, and `InlineArray` (use-after-free / double-free)

Several methods in sized-chunks drop elements before updating the 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's own Drop runs, those elements are visit...
