Stack Exhaustion occurs in the C++ demangling functions provided by libiberty, and there are recursive stack frames: demangle_arm_hp_template, demangle_class_name, demangle_fund_type, do_type, do_arg, demangle_args, and demangle_nested_args. This can occur during execution of nm-new.

Resource Exhaustion

The ignore_section_sym function in elf.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.30, does not validate the output_section pointer in the case of a symtab entry with a "SECTION" type
