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 ...

CVE-2020-8897 Robustness weakness in AWS KMS and Encryption SDKs

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...

openGauss: Configuring the SSL Encryption Algorithm

sslciphers specifies the SSL encryption algorithms used for secure connections. openGauss supports the following algorithms: - DHE-RSA-AES256-GCM-SHA384 - DHE-RSA-AES128-GCM-SHA256 - DHE-DSS-AES256-GCM-SHA384 - DHE-DSS-AES128-GCM-SHA256 - DHE-RSA-AES256-SHA256 - DHE-RSA-AES128-SHA256 -...

CVE-2020-8912

A vulnerability in the in-band key negotiation exists in the AWS S3 Crypto SDK for GoLang versions prior to V2. An attacker with write access to the targeted bucket can change the encryption algorithm of an object in the bucket, which can then allow them to change AES-GCM to AES-CTR. Using this i...
