Summary

Denial of service on EVM execution due to memory over-allocation

Details

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.

The flaw was corrected in commit 19ade85.
