Detailsinfo

A vulnerability classified as problematic was found in polkadot-evm frontier (the affected version unknown). Affected by this vulnerability is the function Curve25519Add/Curve25519ScalarMul. The manipulation with an unknown input leads to a risky encryption vulnerability. The CWE definition for the vulnerability is CWE-327. The product uses a broken or risky cryptographic algorithm or protocol. As an impact it is known to affect confidentiality. The summary by CVE is:

Polkadot Frontier is an Ethereum and EVM compatibility layer for Polkadot and Substrate. In versions prior to commit 36f70d1, the Curve25519Add and Curve25519ScalarMul precompiles incorrectly handle invalid Ristretto point representations. Instead of returning an error, they silently treat invalid input bytes as the Ristretto identity element, leading to potentially incorrect cryptographic results. This is fixed in commit 36f70d1.
