CVE-2024-53589

Process crash via invalid tekhex section traversal

Published Dec 5, 2024 · Updated Mar 14, 2025

Buffer overflow in GNU Binutils objdump 2.43 allows local users to crash the process by supplying a crafted tekhex file for inspection. BFD's tekhex first_phase function passes bfd_abs_section_ptr to bfd_get_next_section_by_name, causing an eight-byte read before _bfd_std_section. The file must be processed by objdump; the demonstrated consequence is an out-of-bounds read and process crash, while code execution remains unverified.
