Double Public Key Signing Function Oracle Attack on ed25519-dalek

Versions of ed25519-dalek prior to v2.0 model private and public keys as
separate types which can be assembled into a Keypair, and also provide APIs
for serializing and deserializing 64-byte private/public keypairs.

Such APIs and serializations are inherently unsafe as the public key is one of
the inputs used in the deterministic computation of the S part of the signature,
but not in the R value. An adversary could somehow use the signing function as
an oracle that allows arbitrary public keys as input can obtain two signatures
for the same message sharing the same R and only differ on the S part.

Unfortunately, when this happens, one can easily extract the private key.

Revised public APIs in v2.0 of ed25519-dalek do NOT allow a decoupled
private/public keypair as signing input, except as part of specially labeled
"hazmat" APIs which are clearly labeled as being dangerous if misused.

libsqlite3-sys via C SQLite CVE-2022-35737

It was sometimes possible for SQLite versions >= 1.0.12, < 3.39.2 to allow an array-bounds overflow when large string were input into SQLite's printf function.

As libsqlite3-sys bundles SQLite, it is susceptible to the vulnerability. libsqlite3-sys was updated to bundle the patched version of SQLite here.
