A Base64-encoded copy of this file is attached at the end of this report. When parsing the file with LIEF, it reports that the binary has no sections at all, but that is inaccurate. Notably, LIEF reports:
Load commands are corrupted
To Reproduce
Assuming the binary is located at /home/john/file.bin, steps to reproduce the behavior (in Python):
>>> from macholib.MachO import MachO
>>> m2 = MachO("/home/john/file.bin")
>>> for header in m2.headers:
... for cmd, segment, sections in header.commands:
... if not cmd.get_cmd_name().startswith('LC_SEGMENT'):
... continue
... if segment.filesize <= 0:
... continue
... for section in sections:
... print(section.sectname.partition(B'\0')[0].decode())
...

Expected behavior
LIEF is expected to extract the same sections / segments as macholib does. For example, IDA Pro identifies the same sections as macholib (in terms of data).
