Py-EVM is vulnerable to arbitrary bytecode injection

Py-EVM v0.2.0-alpha.33 allows attackers to make a vm.executebytecode call that triggers computation.stack.values with '"stack": 100, 100, 0' where b'\x' was expected, resulting in an execution failure because of an invalid opcode. This is reportedly related to "smart contracts can be executed...

Denial Of Service (DoS)

py-evm is vulnerable to a denial of service DoS attack. A malicious user can pass a contract to the application to cause invalid values in the stack, crashing the application...

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...
