evm is a pure Rust implementation of Ethereum Virtual Machine. Prior to the patch, when executing specific EVM opcodes related to memory operations that use
evm_core::Memory::copy_large, theevmcrate can over-allocate memory when it is not needed, making it possible for an attacker to perform denial-of-service attack. The flaw was corrected in commit19ade85. Users should upgrade to==0.21.1, ==0.23.1, ==0.24.1, ==0.25.1, >=0.26.1. There are no workarounds. Please upgrade yourevmcrate version. - References
