Description

alloy-dyn-abi has DoS vulnerability on alloy_dyn_abi::TypedData hashing

Impact

An uncaught panic triggered by malformed input to alloy_dyn_abi::TypedData could lead to a denial-of-service (DoS) via eip712_signing_hash().

Software with high availability requirements such as network services may be particularly impacted. If in use, external auto-restarting mechanisms can partially mitigate the availability issues unless repeated attacks are possible.

Patches

The vulnerability was patched by adding a check to ensure the element is not empty before accessing its first element; an error is returned if it is empty. The fix is included in version [v1.4.1](https://crates.io/crates/alloy-dyn-abi/1.4.1) and backported to [v0.8.26](https://crates.io/crates/alloy-dyn-abi/0.8.26).

Workarounds

There is no known workaround that mitigates the vulnerability. Upgrading to a patched version is the recommended course of action.
