CVE-2022-40922Network attack vector

Denial of service via Mach-O parser crash

Published Oct 3, 2022 · Updated Aug 3, 2024

Denial-of-service vulnerability in LIEF v0.12.1 allows remote attackers to interrupt parsing via a crafted Mach-O file. The LIEF::MachO::BinaryParser::init_and_parse function dereferences malformed Mach-O data and can terminate the process with a segmentation fault. Exploitation requires a parsing service or application to accept the attacker-controlled file; the demonstrated consequence is service interruption without reported confidentiality or integrity impact.
