Description Laura Pardo 2018-04-05 22:26:07 UTC
A flaw was discovered in cplus-dem.c in GNU libiberty, as distributed in GNU Binutils 2.29 and 2.30. Stack Exhaustion occurs in the the C++ demangling functions provided by libiberty, and there are recursive stack frames: demangle_nested_args, demangle_args, do_arg, and do_type.
