CVE-2024-32609Network attack vector

Process crash via recursive error-stack reporting

Published May 9, 2024 · Updated Feb 13, 2025

Uncontrolled recursion in The HDF Group HDF5 1.14.3 and earlier allows remote attackers to exhaust the process stack during error reporting. H5E__push_stack calls an error-producing reference increment for an invalid identifier; that failure invokes H5E_printf_stack again and recursively repeats the same path. Public sources do not identify the application operation or input that supplies the invalid identifier, so exposure depends on a caller reaching this error path.
