CVE-2025-62370
Alloy Core has a DoS vulnerability on `alloy_dyn_abi::TypedData` hashing
Description
Alloy Core libraries at the root of the Rust Ethereum ecosystem. Prior to 0.8.26 and 1.4.1, 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. 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 and backported to v0.8.26.

Action Type Old Value New Value Added Translation Title: core de alloy-rs, Description: Bibliotecas Alloy Core en la raíz del ecosistema Rust Ethereum. Antes de las versiones 0.8.26 y 1.4.1, un error de pánico no capturado, provocado por una entrada malformada a alloy_dyn_abi::TypedData, podría conducir a una denegación de servicio (DoS) a través de eip712_signing_hash(). El software con requisitos de alta disponibilidad, como los servicios de red, podría verse particularmente afectado. Si se utilizan, los mecanismos externos de reinicio automático pueden mitigar parcialmente los problemas de disponibilidad, a menos que sean posibles ataques repetidos. La vulnerabilidad fue parcheada añadiendo una comprobación para asegurar que el elemento no esté vacío antes de acceder a su primer elemento; se devuelve un error si está vacío. La corrección está incluida en la versión v1.4.1 y se ha retroportado a la v0.8.26. -
