manticore - Manticore 0.3.0

0.3.0 - 2019-06-06

Thanks to our external contributors!

Major Changes

Executor Refactor (#1385)

We've completed a major refactor of the core executor that reorganizes Manticore's state machine to be more amenable toward use with the multiprocesssing module. This refactor introduces some small API changes: * One must explicitly call the finalize method to dump test cases from a run * The will_start_run event has been renamed to will_run * The solver module requires explicitly accessing the Z3Solver singleton. from manticore.core.smtlib import solver becomes: python from manticore.core.smtlib.solver import Z3Solver solver = Z3Solver.instance() * manticore.running_states has been renamed to manticore._busy_states For more information about changes to the state machine, see the diagram in core/manticore.py

Blacken (#1438)

We've run the black autoformatter on the master branch of Manticore, and added a check for compliance to our CI. To ensure your code is properly formatted, run black -t py36 -l 100 . in your Manticore directory before committing.

Support for statically-linked AArch64 binaries (#1424)

Contractor nkaretnikov spent several months adding support for AArch64 on Linux. As this is a brand new architecture, we've left in most of the debugging assertions, which may slow it down slightly. We look forward to getting feedback on this architecture so we can eventually remove the debugging assertions.

Ethereum

Added Symbolic EVM Tests for the Frontier fork. Note that we don't support any other forks (i.e. Constantinople) yet. (#1431, #1441)
[fixed API] Fixed relative paths for .sol files (#1393)
[fixed API] Support dynamic parameters in constructors (#1414)
Fixed detector failure when PC is symbolic (#1395)
Transfers from etherless contracts no longer report STOP (#1392)

Native

Added stubs for missing system calls & downgraded most missing calls from exceptions to warnings (#1384)
Fixed DECREE magic pages (#1413)
Store x86 registers in a set instead of a list (#1415)
Fix register boundary check for non-x86 architectures (#1429)

manticore - Manticore 0.2.5

0.2.5 - 2019-03-18

Thanks to our external contributors!

Manticore 0.2.5 added Unicorn preloading for quickly performing concrete emulation of native binaries until a target address is reached. In the EVM engine, apart from some fixes, this release added support for creating contracts from Truffle JSON artifacts (see jsoncreatecontract).

Full changelog below.

Ethereum

[added API] json_create_contract - support creating EVM contracts from Truffle JSON artifacts (#1376)
[changed API] Moved default gas value to config module (#1346)
[fixed API] Fixed account creation with a code field (#1371)
[fixed API] Fixed an incorrect attribute in last_return (#1341)
[refactor] Inlined get_possible solutions function as it's only used once (#1372)
Fixed _check_jumpdest when run with detectors - this bug could lead to not detecting an int overflow due to tainting made by another detector (#1347)
Made findings print addresses in hex (#1339)

Native

[added API] Added Unicorn preloading, for quickly performing concrete emulation until a target address is reached. (#1356)

Published by ehennenfent about 7 years ago

manticore - Manticore 0.2.4

0.2.4 - 2019-01-10

Ethereum

[added API] Fixed VerboseTrace plugin (#1305) and added VerboseTraceStdout plugin (#1305): those can be used to track EVM execution (m.regiser_plugin(VerboseTraceStdout()))
[changed API] Made gas calculation faithfulness configurable: this way, you can choose whether you respect or ignore gas calculations with --evm.oog <opt> (see --help); also, the gas calculations has been decoupled into its own methods (#1279)
[changed API] Changed default gas to 3000000 when creating contract (#1332)
[changed API] Launching manticore from cli will display all registered plugins (#1301)

Native

[added API] Added symbol resolution feature, so it is possible to grab a symbol address by using m.resolve(symbol) (#1302)
[changed API] The stdin_size CLI argument has been moved to config constant and so has to be passed using --native.stdin_size instead of --stdin_size (#1337)
Speeded up Armv7 execution a bit (#1313)
Fixed sys_arch_prctl syscall when wrong code value was passed and raise a NotImplementedError instead of asserting for not supported code values (#1319)

Other

manticore - Manticore 0.2.3

0.2.3 - 2018-12-11

Thanks to our external contributors!

Added

Support for ARM THUMB instructions: ADR, ADDW, SUBW, CBZ, TBB, TBH, STMDA, STMDB
State.solve_minmax() API for querying a BitVec for its min/max values
New SMTLIB optimization for simplifying redundant concat/extract combinations; helps reduce expression complexity, and speed up queries
Ethereum: --txpreconstrain CLI flag. Enabling this avoids sending ether to nonpayable functions, primarily avoiding exploration of uninteresting revert states.
Research memory model (LazySMemory) allowing for symbolic memory indexing to be handled without concretization (opt in, currently for research only)

Changed

Linux/binary analysis has been moved to manticore.native, manticore.core.cpu has been moved to manticore.native.cpu. Please update your imports.
The binary analysis dependencies are now not installed by default. They can be installed with pip install manticore[native]. This is to prevent EVM users from installing binary dependencies.
The symbolic stdin_size is now a config variable (in main config group) with a default of 256 (it was like this before).
ManticoreEVM.generate_testcase() 'name' parameter is now optional
Manticore CLI run on a smart contract will now use all detectors by default (detectors can be listed with --list-detectors, excluded with --exclude or --exclude-all)
Misusing the ManticoreEVM API, for example by using old keyword arguments that are not available since some versions (like ManticoreEVM(verbosity=5)) will now raise an exception instead of not applying the argument at all.

Fixed

Ethereum: Fixed CLI timeout support
Numerous EVM correctness fixes for Frontier fork
Fixed handling of default storage and memory in EVM (reading from previously unused cell will return a zero now)
ARM THUMB mode, Linux syscall emulation fixes
Creation of multiple contracts with symbolic arguments (ManticoreEVM.soliditycreatecontract with args=None fired more than once failed before)

Removed

Manticore.evm static method

manticore - Manticore 0.2.2

0.2.2 - 2018-10-30

Thanks to our external contributors!

Added

New API for generating a testcase only if a certain condition can be true in the state. Useful for conveniently checking an invariant in a state, and (ManticoreEVM.generate_testcase(..., only_if=)) generating a testcase if it can be violated.
New constrain= optional parameter for State.solve_one and State.solve_buffer. After solving for a symbolic variable, mutate the state by applying that solution as a constraint. Useful if concretizing a few symbolic variables, and later concretizations should take into account previously solved for values.
ManticoreEVM.human_transactions top level API. Mirrors ManticoreEVM.transactions, but does not contain any internal transactions.
Emit generated transaction data in human readable format (JSON)
Warning messages if number of passed arguments to a Solidity function is inconsistent with the number declared
CLI support for the ReentrancyAdvancedDetector
Colored CLI output
Configuration system. Allows configuration options to be specified in a config file. New configurations are available, notably including solver parameters such as solver timeout, and memory limits.
Support for some unimplemented x86 XMM instructions
Customizable symbolic stdin input buffer size
Support for Etheno
RaceConditionDetector that can be used to detect transaction order dependencies bugs

Changed

Improve the DetectExternalCallAndLeak detector and reduce false positives
Numerous improvements and changes to the SolidityMetadata API
Ethereum contract addresses are no longer random, but are deterministically calculated according to the Yellow Paper
Manticore no longer supports contracts with symbolic addresses creating new contracts. This is a consequence of supporting determinstic contrat address calculation. There are plans for reenabling this capability in a future release.

Deprecated

Several SolidityMetadata APIs: .get_hash(), .functions, .hashes

Fixed

Numerous fixes and enhancements to the Ethereum ABI implementation
Better handling of overloaded functions in SolidityMetadata, and other bug fixes
Fixes for the FilterFunctions plugin
Fixes for symbolic SHA3 handling
Many EVM correctness/consensus fixes
Numerous spelling errors

manticore - Manticore 0.2.1.1

0.2.1.1 - 2018-09-01

Manticore has been relicensed to AGPLv3. Please contact us if you're looking for an exception to these terms.

Thanks to our external contributors!

Added

Full suite of Ethereum detectors
- Selfdestruct (--detect-selfdestruct): Warns if a selfdestruct instruction is reachable by the user
- External Call (--detect-externalcall): Warns if there is a call to the user, or a user controlled address with ether.
- Reentrancy (--detect-reentrancy): Warns if there is a change of storage state after a call to the user, or a user controlled address, with >2300 gas. This is an alternate implementation enabled in the CLI. The previous implementation is still available for API use (DetectReentrancyAdvanced).
- Delegatecall (--detect-delegatecall): Warns if there is a delegatecall to a user controlled address, or to a user controlled function.
- Environmental Instructions (--detect-env): Warns if certain instructions are used that can be potentially manipulated. Instructions: BLOCKHASH, COINBASE, TIMESTAMP, NUMBER, DIFFICULTY, GASLIMIT, ORIGIN, GASPRICE.
New Ethereum command line flags
- --no-testcases: Do not generate testcases for discovered states
- --txnoether: Do not make the transaction value symbolic in executed transactions
SMTLIB: Advanced functionality for expression migration. Expressions from arbitrary constraint sets can be mixed to create arbitrary constraints, expressions are transparently migrated from constraint set to another, avoiding SMT naming collisions.

Changed

Command line interface uses a new reentrancy detector based on detection of user controlled call addresses

Fixed

Ethereum: Support for overloaded solidity functions
Ethereum: Significantly improved ability to create symbolic variables and constraints at the global level
Ethereum: Improved gas support
State serialization improvements and fixes

This release brings improved Ethereum support, performance improvements, and numerous bug fixes. Thanks to our external contributors!

A few comments on Ethereum support:

Manticore includes an implementation of a symbolic Ethereum Virtual Machine (EVM), an EVM disassembler/assembler, and a convenient interface for automated compilation and analysis of Solidity. It also integrates with Ethersplay, Trail of Bits’ visual disassembler for EVM bytecode, for analysis visualization. As with binaries, Manticore offers a simple command line interface and a Python API for analysis of EVM bytecode. See a demo: https://asciinema.org/a/154012

EVM features in Manticore are under active development and bounties are available for feature enhancements and bugfixes. Join us on the Empire Hacking Slack in #ethereum to discuss using or hacking on these EVM features with the developers.
