Description

The Amazon S3 Encryption Client for .NET is an open-source client-side encryption library used to facilitate writing and reading encrypted records to S3. Missing cryptographic key commitment in the Amazon S3 Encryption Client for .NET may allow a user with write access to the S3 bucket to introduce a new EDK that decrypts to different plaintext when the encrypted data key is stored in an "instruction file" instead of S3's metadata record. To mitigate this issue, upgrade Amazon S3 Encryption Client for .NET to version 3.2.0 or later.
