CVE-2023-45130

Summary

CVE-2023-45130 is a vulnerability affecting Frontier, Substrate's Ethereum compatibility layer. Prior to commit aea528198b3b226e0d20cce878551fd4c0e3d5d0, when a contract is marked for deletion using the opcode SUICIDE, the software uses an IO primitive call to remove associated storages. For large contracts or parachains with extensive storage usage, this call can cause the Proof of Verification (PoV) size to exceed the relay chain's limit, leading to stalling. The maintainers consider this issue severe due to potential denial-of-service attacks using large contracts on parachains. The patch for this issue is included in commit aea528198b3b226e0d20cce878551fd4c0e3d5d0. Parachains should issue an emergency runtime upgrade as soon as possible, while standalone chains should perform a normal runtime upgrade. No known workarounds exist.
