CVE-2022-43171Public exploitNetwork attack vector

Application crash via out-of-bounds generic-bind read

Published Nov 17, 2022 · Updated Apr 29, 2025

Heap buffer overflow in LIEF before 0.12.3 allows attackers to crash applications that parse a crafted Mach-O file. The parse_dyldinfo_generic_bind function performs an unchecked read past its heap-backed segment collection while interpreting corrupted generic-bind data. Exploitation requires a consuming application to parse the supplied file and terminates that parsing process without reported data disclosure or modification.
