New! CVE Severity Now Using CVSS v3

The calculated severity for CVEs has been updated to use CVSS v3 by default. CVEs that do not have a CVSS v3 score will fall back CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Description

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.
