github.com/kyverno/kyverno is vulnerable to Denial of Service (DoS). An attacker with control over the registry from which Kyverno fetches signatures could exploit this vulnerability by returning a malicious response to Kyverno’s request. The malicious response could be a malformed signature or a signature that is not for the attestation that Kyverno is expecting. If Kyverno receives a malicious response, it will be unable to verify the signature and will crash. This will prevent Kyverno from processing any admission requests, which will cause a DoS.
