The get_count function in cplus-dem.c in GNU libiberty, as distributed in
GNU Binutils 2.31, allows remote attackers to cause a denial of service
(malloc called with the result of an integer-overflowing calculation) or
possibly have unspecified other impact via a crafted string, as
demonstrated by c++filt.
