Functions

func NormalizeSeverity

func NormalizeSeverity(severity string) claircore.Severity

func UpdaterSet

func UpdaterSet() (driver.UpdaterSet, error)

Types

type DistributionScanner

type DistributionScanner struct{}

DistributionScanner attempts to discover if a layer displays characteristics of a Oracle distribution

func (*DistributionScanner) Kind

func (*DistributionScanner) Kind() string

Kind implements scanner.VersionedScanner.

func (*DistributionScanner) Name

func (*DistributionScanner) Name() string

Name implements scanner.VersionedScanner.

func (*DistributionScanner) Scan

func (ds *DistributionScanner) Scan(ctx context.Context, l *claircore.Layer) ([]*claircore.Distribution, error)

Scan will inspect the layer for an os-release or lsb-release file and perform a regex match for keywords indicating the associated Oracle release

If neither file is found a (nil,nil) is returned. If the files are found but all regexp fail to match an empty slice is returned.

func (*DistributionScanner) Version

func (*DistributionScanner) Version() string

Version implements scanner.VersionedScanner.

type Matcher

type Matcher struct{}

Matcher implements driver.Matcher.

func (*Matcher) Filter

func (*Matcher) Filter(record *claircore.IndexRecord) bool

Filter implements driver.Matcher.

func (*Matcher) Name

func (*Matcher) Name() string

Name implements driver.Matcher.

func (*Matcher) Query

func (*Matcher) Query() []driver.MatchConstraint

Query implements driver.Matcher.

func (*Matcher) Vulnerable

func (*Matcher) Vulnerable(record *claircore.IndexRecord, vuln *claircore.Vulnerability) bool

Vulnerable implements driver.Matcher.

type Option

type Option func(*Updater) error

Option is a type to configure an Updater.

func WithClient

func WithClient(c *http.Client) Option

WithClient sets an http.Client for use with an Updater.

If this Option is not supplied, http.DefaultClient will be used.

func WithURL

func WithURL(uri, compression string) Option

WithURL overrides the default URL to fetch an OVAL database.

type Release

type Release int

const (
	RHEL3 Release = 3
	RHEL4 Release = 4
	RHEL5 Release = 5
	RHEL6 Release = 6
	RHEL7 Release = 7
	RHEL8 Release = 8
)

type Updater

type Updater struct {
	ovalutil.Fetcher // fetch method promoted via embed
	// contains filtered or unexported fields
}

Updater fetches and parses RHEL-flavored OVAL databases.

func NewUpdater

func NewUpdater(v Release, opt ...Option) (*Updater, error)

NewUpdater returns an Updater.

func (*Updater) Name

func (u *Updater) Name() string

Name satisifies the driver.Updater interface.

func (*Updater) Parse

func (u *Updater) Parse(ctx context.Context, r io.ReadCloser) ([]*claircore.Vulnerability, error)
