# CLE [![Latest Release](https://img.shields.io/pypi/v/cle.svg)](https://pypi.python.org/pypi/cle/) [![Python Version](https://img.shields.io/pypi/pyversions/cle)](https://pypi.python.org/pypi/cle/) [![PyPI Statistics](https://img.shields.io/pypi/dm/cle.svg)](https://pypistats.org/packages/cle) [![License](https://img.shields.io/github/license/angr/cle.svg)](https://github.com/angr/cle/blob/master/LICENSE) CLE loads binaries and their associated libraries, resolves imports and provides an abstraction of process memory the same way as if it was loader by the OS's loader. ## Project Links Project repository: https://github.com/angr/cle Documentation: https://api.angr.io/projects/cle/en/latest/ ## Installation ```sh pip install cle ``` ## Usage example ```python >>> import cle >>> ld = cle.Loader("/bin/ls") >>> hex(ld.main_object.entry) '0x4048d0' >>> ld.shared_objects {'ld-linux-x86-64.so.2': <ELF Object ld-2.21.so, maps [0x5000000:0x522312f]>, 'libacl.so.1': <ELF Object libacl.so.1.1.0, maps [0x2000000:0x220829f]>, 'libattr.so.1': <ELF Object libattr.so.1.1.0, maps [0x4000000:0x4204177]>, 'libc.so.6': <ELF Object libc-2.21.so, maps [0x3000000:0x33a1a0f]>, 'libcap.so.2': <ELF Object libcap.so.2.24, maps [0x1000000:0x1203c37]>} >>> ld.addr_belongs_to_object(0x5000000) <ELF Object ld-2.21.so, maps [0x5000000:0x522312f]> >>> libc_main_reloc = ld.main_object.imports['__libc_start_main'] >>> hex(libc_main_reloc.addr) # Address of GOT entry for libc_start_main '0x61c1c0' >>> import pyvex >>> some_text_data = ld.memory.load(ld.main_object.entry, 0x100) >>> irsb = pyvex.lift(some_text_data, ld.main_object.entry, ld.main_object.arch) >>> irsb.pp() IRSB { t0:Ity_I32 t1:Ity_I32 t2:Ity_I32 t3:Ity_I64 t4:Ity_I64 t5:Ity_I64 t6:Ity_I32 t7:Ity_I64 t8:Ity_I32 t9:Ity_I64 t10:Ity_I64 t11:Ity_I64 t12:Ity_I64 t13:Ity_I64 t14:Ity_I64 15 | ------ IMark(0x4048d0, 2, 0) ------ 16 | t5 = 32Uto64(0x00000000) 17 | PUT(rbp) = t5 18 | t7 = GET:I64(rbp) 19 | t6 = 64to32(t7) 20 | t2 = t6 21 | t9 = GET:I64(rbp) 22 | t8 = 64to32(t9) 23 | t1 = t8 24 | t0 = Xor32(t2,t1) 25 | PUT(cc_op) = 0x0000000000000013 26 | t10 = 32Uto64(t0) 27 | PUT(cc_dep1) = t10 28 | PUT(cc_dep2) = 0x0000000000000000 29 | t11 = 32Uto64(t0) 30 | PUT(rbp) = t11 31 | PUT(rip) = 0x00000000004048d2 32 | ------ IMark(0x4048d2, 3, 0) ------ 33 | t12 = GET:I64(rdx) 34 | PUT(r9) = t12 35 | PUT(rip) = 0x00000000004048d5 36 | ------ IMark(0x4048d5, 1, 0) ------ 37 | t4 = GET:I64(rsp) 38 | t3 = LDle:I64(t4) 39 | t13 = Add64(t4,0x0000000000000008) 40 | PUT(rsp) = t13 41 | PUT(rsi) = t3 42 | PUT(rip) = 0x00000000004048d6 43 | t14 = GET:I64(rip) NEXT: PUT(rip) = t14; Ijk_Boring } ``` ## Valid options For a full listing and description of the options that can be provided to the loader and the methods it provides, please examine the docstrings in `cle/loader.py`. If anything is unclear or poorly documented (there is much) please complain through whatever channel you feel appropriate. ## Loading Backends CLE's loader is implemented in the Loader class. There are several backends that can be used to load a single file: - ELF, as its name says, loads ELF binaries. ELF files loaded this way are statically parsed using PyElfTools. - PE is a backend to load Microsoft's Portable Executable format, effectively Windows binaries. It uses the (optional) `pefile` module. - Mach-O is a backend to load, you guessed it, Mach-O binaries. It is subject to several limitations, which you can read about in the [readme in the macho directory](backends/macho/README.md) - Blob is a backend to load unknown data. It requires that you specify the architecture it would be run on, in the form of a class from ArchInfo. Which backend you use can be specified as an argument to Loader. If left unspecified, the loader will pick a reasonable default. ## Finding shared libraries - If the `auto_load_libs` option is set to False, the Loader will not automatically load libraries requested by loaded objects. Otherwise... - The loader determines which shared objects are needed when loading binaries, and searches for them in the following order: - in the current working directory - in folders specified in the `ld_path` option - in the same folder as the main binary - in the system (in the corresponding library path for the architecture of the binary, e.g., /usr/arm-linux-gnueabi/lib for ARM, note that you need to install cross libraries for this, e.g., libc6-powerpc-cross on Debian - needs emdebian repos) - in the system, but with mismatched version numbers from what is specified as a dependency, if the `ignore_import_version_numbers` option is True - If no binary is found with the correct architecture, the loader raises an exception if `except_missing_libs` option is True. Otherwise it simply leaves the dependencies unresolved.
