  • update release images to use go1.19.2 and cosign v1.12.1 by @cpanato in https://github.com/sigstore/cosign/pull/2315

cosign was updated to 1.12.1:

  • fix: Pulls Fulcio root and intermediate when --certificate-chain is not passed into verify-blob command. The v1.12.0 release introduced a regression: when COSIGN_EXPERIMENTAL was not set, cosign verify-blob would check a --certificate (without a --certificate-chain provided) against the operating system root CA bundle. In this release, Cosign checks the certificate against Fulcio's CA root instead (restoring the earlier behavior).
  • fix: fix cert chain validation for verify-blob in non-experimental mode
  • fix: add COSIGN_EXPERIMENTAL=1 for verify-bloba
  • Fix BYO-root with intermediate to fetch intermediates from annotation
  • fix: fixing breaking changes in rekor v1.12.0 upgrade
