Details

Memory over-allocation in evm crate ### Impact Prior to the patch, when executing specific EVM opcodes related to memory operations that use `evm_core::Memory::copy_large`, the crate can over-allocate memory when it is not needed, making it possible for an attacker to perform denial-of-service attack. ### Patches The flaw was corrected in commit `19ade85`. Users should upgrade to `==0.21.1, ==0.23.1, ==0.24.1, ==0.25.1, >=0.26.1`. ### Workarounds None. Please upgrade your `evm` crate version ### References Fix commit: https://github.com/rust-blockchain/evm/commit/19ade858c430ab13eb562764a870ac9f8506f8dd ### For more information If you have any questions or comments about this advisory: * Open an issue in [evm repo](https://github.com/rust-blockchain/evm) * Email [Wei](mailto:wei@that.world)
