An issue was discovered in cp-demangle.c in GNU libiberty, as distributed in GNU Binutils 2.31. Stack Exhaustion occurs in the C++ demangling functions provided by libiberty, and there is a stack consumption problem caused by recursive stack frames: cplus_demangle_type, d_bare_function_type, d_function_type.
Weakness
The product does not properly control the amount of recursion that takes place, consuming excessive resources, such as allocated memory or the program stack.
