Functions

func SeverityFromCVSS

func SeverityFromCVSS(score float64) database.Severity

SeverityFromCVSS converts the CVSS Score (0.0 - 10.0) into a database.Severity following the qualitative rating scale available in the CVSS v3.0 specification (https://www.first.org/cvss/specification-document), Table 14.

The Negligible level is set for CVSS scores between [0, 1), replacing the specified None level, originally used for a score of 0.

Types

type NVDMetadata

type NVDMetadata struct {
	CVSSv2 NVDmetadataCVSSv2
}

type NVDmetadataCVSSv2

type NVDmetadataCVSSv2 struct {
	Vectors string
	Score   float64
}

type NestedReadCloser

type NestedReadCloser struct {
	io.Reader
	NestedReadClosers []io.ReadCloser
}

NestedReadCloser wraps an io.Reader and implements io.ReadCloser by closing every embed io.ReadCloser. It allows chaining io.ReadCloser together and still keep the ability to close them all in a simple manner.

func (*NestedReadCloser) Close

func (nrc *NestedReadCloser) Close()

Close closes the gzip.Reader and the underlying io.ReadCloser.
