Description
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.
