CVE-2024-38443Public exploit

Program crash via unbounded recursive sorting

Published Jun 16, 2024 · Updated Aug 2, 2024

Stack overflow in binary_insertion_sort.c in The Algorithms C through e5dad3f allows local users to crash the program via crafted array input. The implementation recursively advances through the array without limiting input size or recursion depth, consuming stack frames until the process faults. The input must reach a locally compiled consumer of this educational source; the demonstrated 50-element case terminates with a segmentation fault, while optimized builds can hang.
