This Affects:
bcpg-jdk18onTL;DR
The high-level OpenPGP API accepts third-party certifications and trust delegations from subkeys that were never granted certification authority, so a restricted subkey can be treated as an introducer. The fix requires a non-primary issuer component to hold CERTIFY_OTHER.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range and you use the high-level OpenPGP certificate API to make identity or introducer-trust decisions from certifications or delegations.
