QID 995855: GO (Go) Security Update for github.com/sigstore/cosign (GHSA-vfp6-jrw2-99g9)

Cosign is susceptible to a denial of service by an attacker controlled registry. An attacker who controls a remote registry can return a high number of attestations and/or signatures to Cosign and cause Cosign to enter a long loop resulting in an endless data attack. The root cause is that Cosign loops through all attestations fetched from the remote registry in pkg/cosign.FetchAttestations.

Successful exploitation of this vulnerability could lead to a security breach or could affect integrity, availability, and confidentiality.
