CVE-2022-1052Public exploit

Process crash via mismatched Mach-O segment counts

Published Mar 24, 2022 · Updated Aug 2, 2024

Heap buffer overflow in radare2 before 5.6.6 allows local users to crash the process by analyzing a crafted Mach-O file. iterate_chained_fixups indexes chained_starts up to bin->nsegs even when the file-derived allocation contains fewer segment entries. Local analysis of attacker-supplied Mach-O input reaches the flaw, causing a heap out-of-bounds read that can terminate the process.
