Bumps sigstore from 4.1.0 to 4.2.0.

Release notes

Sourced from sigstore's releases.

v4.2.0

This release fixes a minor security issue in OIDC authentication and a compatibility issue with Fulcio Signed Certificate Timestamps. All users are recommended to upgrade.

Fixed

  • Add state validation to OIDC flow to prevent Cross-site request forgery during OIDC authorization (GHSA-hm8f-75xx-w2vr)
  • verification now ensures that artifact digest documented in bundle and the real digest match (this is a bundle consistency check: bundle signature was always verified over real digest) (#1652)
  • Fix issue with Signed Certificate Timestamp parsing where extensions were not allowed by sigstore-python (1657, 1659)

Changed

  • Update supported public key algorithms (#1604)
  • trust: Update embedded TUF root (#1589)

Removed

  • Removed support for Python 3.9 as it is end-of-life (#1645)
  • Removed unused nonce in Oauth flow (#1649)
