CVE-2020-26241 Shallow copy bug in geth

Go Ethereum, or "Geth", is the official Golang implementation of the Ethereum protocol. This is a Consensus vulnerability in Geth before version 1.9.17 which can be used to cause a chain-split where vulnerable nodes reject the canonical chain. Geth's pre-compiled dataCopy at 0x00...04 contract di...

CVE-2020-26241

CVE-2020-26241 is a consensus vulnerability in the Go Ethereum (Geth) client prior to version 1.9.17. A crafted contract can trigger a mismatch between the EVM’s RETURNDATACOPY path and Geth’s execution by exploiting a shallow copy bug in the pre-compiled dataCopy contract (0x0000…04). An attacke...

CVE-2020-26242

Go Ethereum (Geth) before version 1.9.18 is vulnerable to a Denial-of-Service (crash) during block processing. The issue stems from the uint256 library behavior (buffer underflow in MULMOD when modulo is 0), which can cause a panic and network-wide node drops if exploited. A fix was released by u...
