GHSA-8W8F-R2XV-4Q4J OpenBao: Transit secrets engine crashes on key creation with `derived: true` for asymmetric key types

On OpenBao 2.5.4 and 2.5.2and likely earlier versions also, an authenticated caller with write access to transit/keys/ can crash the OpenBao server by issuing a single key-creation request that combines an asymmetric type rsa-, ecdsa-, ed25519 with derived: true. The server returns no HTTP respon...
