CVE-2022-0713

Information disclosure and crash via truncated CoreSymbolication segment

Published Feb 22, 2022 · Updated Aug 2, 2024

Heap buffer overflow in radare2 before 5.6.4 allows attackers to disclose memory or crash the tool through a crafted Mach-O file. The r_coresym_cache_element_new segment loop checks only that its cursor is below the buffer end before reading a complete segment structure, causing a truncated element to be read past the allocation. A victim must open the crafted file; the published assessment reports confidentiality and availability impact but no data modification.
