Module pwn::elf

Utilities for parsing ELF files.

Examples

Loading from a file

ELF files are memory-mapped into the process, reducing their memory footprint.

use pwn::Elf;
let e = Elf::new("/tmp/binary");
dbg!(e.got().get("puts"));

use pwn::Elf;
let e = Elf::from_bytes(b"\x7fELF...");
dbg!(e.got().get("puts"));

Symbols in the ELF, GOT and PLT are lazily resolved on request, reducing initial load delay.

ELF files can also have their load address changed, which will rebase all their values.

use pwn::Elf;
let mut e = Elf::from_bytes(b"\x7fELF...");
// Relocatable files have their address set to 0
assert_eq!(e.address(), 0);
let orig = *e.got().get("puts").unwrap();
e.set_address(0x5000);
assert_eq!(*e.got().get("puts").unwrap(), orig+0x5000);
