Summary
rusty_paseto vulnerable to private key extraction due to ed25519-dalek dependency
Details

Impact

The vulnerability, known as RUSTSEC-2022-0093, impacts the ed25519-dalek crate, which is a dependency of the rusty-paseto crate. This issue arises from a "Double Public Key Signing Function Oracle Attack" affecting versions of ed25519-dalek prior to v2.0. These versions expose an unsafe API for serializing and deserializing 64-byte keypairs that include both private and public keys, creating potential for certain attacks. d25519-dalek users utilizing these serialization and deserialization functions directly could potentially be impacted.

Patches

The vulnerability within the ed25519-dalek crate has been addressed in version 2.0. rusty-paseto has addressed it in release v0.6.0.

Workarounds

Users are recommended to upgrade to v0.6.0 of rusty-paseto. However, users should still ensure that their key serialization and deserialization practices are secure and avoid any practices that could lead to key exposure.
