Elfutils completely fails to read the file: $ eu-readelf --version eu-readelf (elfutils) 0.169 Copyright [...] $ eu-readelf -a hello eu-readelf: failed reading 'hello': invalid file descriptor It's not clear that we should care, since that page even says it's "a completely corrupted x86 ELF Binary that still runs." But since it's good enough for the kernel to run it, I'd hope for *something* from tools. It also seems weird to get the message "invalid file descriptor", from ELF_E_INVALID_FILE, which makes it sound like more like EBADF. The file descriptor itself is fine - it just doesn't like the ELF within. (DWARF_E_INVALID_FILE's message is just "invalid file".) FWIW, binutils readelf does better: $ readelf --version GNU readelf version 2.27-24.fc26 Copyright [...] $ readelf -a hello ELF Header: Magic: 7f 45 4c 46 01 01 01 48 69 20 57 6f 72 6c 64 0a Class: ELF32 Data: 2's complement, little endian Version: 1 (current) OS/ABI: <unknown: 48> ABI Version: 105 Type: EXEC (Executable file) Machine: Intel 80386 Version: 0x1 Entry point address: 0x8048080 Start of program headers: 52 (bytes into file) Start of section headers: 309248 (bytes into file) Flags: 0x80cd0000 Size of this header: 22763 (bytes) Size of program headers: 32 (bytes) Number of program headers: 2 Size of section headers: 40 (bytes) Number of section headers: 5 Section header string table index: 4 readelf: hello: Error: Reading 0xc8 bytes extends past end of file for section headers readelf: hello: Error: Section headers are not available!
