CVE-2018-18483 (opens in a new tab)Amendment
The Ubuntu security team deemed this advisory irrelevant for Ubuntu:19.10.
NVD Description
Note: Versions mentioned in the description apply only to the upstream libiberty package and not the libiberty package as distributed by Ubuntu.
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.
