CVE-2018-18920

CVE-2018-18920 concerns Py-EVM v0.2.0-alpha.33, where a crafted vm.execute_bytecode call can manipulate computation._stack.values (e.g., "stack": [100, 100, 0]) in a way that expects a certain byte (b'\x') and results in an invalid opcode, causing execution failure. The description ties this to a...
