Name of the Vulnerable Software and Affected Versions: Encryption SDK versions prior to 1.9 Encryption SDK versions prior to 2.2 Description: This issue concerns the Encryption SDK's handling of streaming signed messages and restricting processing of certain types of invalid messages. The SDK...

Improper Verification of Cryptographic Signature in aws-encryption-sdk-javascript

This ESDK supports a streaming mode where callers may stream the plaintext of signed messages before the ECDSA signature is validated. In addition to these signatures, the ESDK uses AES-GCM encryption and all plaintext is verified before being released to a caller. There is no impact on the...

CVE-2020-8897

A weak robustness vulnerability exists in the AWS Encryption SDKs for Java, Python, C and Javalcript prior to versions 2.0.0. Due to the non-committing property of AES-GCM and other AEAD ciphers such as AES-GCM-SIV or XChaCha20Poly1305 used by the SDKs to encrypt messages, an attacker can craft a...

CVE-2020-8897

CVE-2020-8897 : A weak robustness vulnerability affects the AWS Encryption SDKs for Java, Python, C and Javalcript prior to 2.0.0. The non-committing property of AES-GCM (and related AEAD ciphers) can let an attacker craft a unique ciphertext that decrypts to multiple different results, which is ...

Amazon AWS Encryption SDK Encryption Issues Vulnerabilities

The Amazon AWS Encryption SDK is a development toolkit for encryption applications from Amazon.com, USA. A security vulnerability exists in the AWS Encryption SDK that stems from the SDK's use of the non-submit attribute of AES-GCM as well as other AEAD ciphers such as AES-GCM-SIV or...
