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

An issue was discovered in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.31. An invalid memory address dereference was discovered in read_reloc in reloc.c. The vulnerability causes a segmentation fault and application crash, which leads to denial of service, as demonstrated by objdump, because of missing _bfd_clear_contents bounds checking.
