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 certain Apple products. macOS before 10.13 Supplemental Update is affected. The issue involves the "StorageKit" component. It allows attackers to discover passwords for APFS encrypted volumes by reading Disk Utility hints, because the stored hint value was accidentally set to the password itself, not the entered hint value.
