CVE-2021-39193
CVE-2021-39193 concerns Frontier’s Ethereum compatibility layer (Frontier) and specifically a bug in the Substrate pallet-ethereum. Before commit 0b962f218f0cdd796dadfe26c3f09e68f7861b26, input data size validation was faulty, which could allow invalid transactions to be included in the Ethereum ...
CVE-2021-39193 Transaction validity oversight in pallet-ethereum
Frontier is Substrate's Ethereum compatibility layer. Prior to commit number 0b962f218f0cdd796dadfe26c3f09e68f7861b26, a bug in pallet-ethereum can cause invalid transactions to be included in the Ethereum block state in pallet-ethereum due to not validating the input data size. Any invalid...
Transaction validity oversight in pallet-ethereum
Impact A bug in pallet-ethereum can cause invalid transactions to be included in the Ethereum block state in pallet-ethereum due to not validating the input data size. Any invalid transactions included this way have no possibility to alter the internal Ethereum or Substrate state. The transaction...

GHSA-9856-9GG9-QCMQ Ethereum Contains Consensus Flaw During Block Processing
Impact A vulnerability in the Geth EVM could cause a node to reject the canonical chain. Description A memory-corruption bug within the EVM can cause a consensus error, where vulnerable nodes obtain a different stateRoot when processing a maliciously crafted transaction. This, in turn, would lead...
