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 bfd_get_debug_link_info_1 function in opncls.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.30, has an unchecked strnlen operation. Remote attackers could leverage this vulnerability to cause a denial of service (segmentation fault) via a crafted ELF file.
