Overview

com.amazonaws:aws-encryption-sdk-java is an AWS Encryption SDK for Java

Affected versions of this package are vulnerable to Improper Verification of Cryptographic Signature. The ESDK supports a streaming mode where callers may stream the plaintext of signed messages before the ECDSA signature is validated.These signatures provide defense in depth and there is no impact on the integrity of decrypted plaintext. Without validating the ECDSA signature, an actor with trusted KMS permissions to decrypt a message may also be able to encrypt messages.
