CVE-2018-18483
Published: 18 October 2018
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.
