x/vulndb: potential Go vuln in github.com/sigstore/policy-controller: CVE-2022-35930

[jba]

CVE-2022-35930 references github.com/sigstore/policy-controller, which may be a Go module.

Description:
PolicyController is a utility used to enforce supply chain policy in Kubernetes clusters. In versions prior to 0.2.1 PolicyController will report a false positive, resulting in an admission when it should not be admitted when there is at least one attestation with a valid signature and there are NO attestations of the type being verified (--type defaults to "custom"). An example image that can be used to test this is ghcr.io/distroless/static@sha256:dd7614b5a12bc4d617b223c588b4e0c833402b8f4991fb5702ea83afad1986e2. Users should upgrade to version 0.2.1 to resolve this issue. There are no workarounds for users unable to upgrade.
