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

Impact This advisory addresses several LOW severity issues with streaming signed messages and restricting processing of certain types of invalid messages. This update addresses an issue where certain invalid ECDSA signatures incorrectly passed validation. These signatures provide defense in depth...

PT-2021-24471

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 affects the Encryption SDK, which supports a streaming mode for signed messages. The SDK uses AES-GCM encryption and verifies plaintext before...

Discovery uses the same AES/GCM Nonce throughout the session

Discovery uses the same AES/GCM Nonce throughout the session though it should be generated on per message basis which can lead to the leaking of the session key. As the actual ENR record is signed with a different key it is not possible for an attacker to alter the ENR record. Note that the node...

CVE-2020-26233

Git Credential Manager Core GCM Core is a secure Git credential helper built on .NET Core that runs on Windows and macOS. In Git Credential Manager Core before version 2.0.289, when recursively cloning a Git repository on Windows with submodules, Git will first clone the top-level repository and...

CVE-2020-6018

Valve's Game Networking Sockets prior to version v1.2.0 improperly handles long encrypted messages in function AESGCMDecryptContext::Decrypt when compiled using libsodium, leading to a Stack-Based Buffer Overflow and resulting in a memory corruption and possibly even a remote code execution...

PT-2020-18893

Name of the Vulnerable Software and Affected Versions Valve's Game Networking Sockets versions prior to v1.2.0 Description The issue arises from the improper handling of long encrypted messages in the AES GCM DecryptContext::Decrypt function when compiled using libsodium. This leads to a...

GaussDB Kernel: Configuring the SSL Encryption Algorithm

sslciphers specifies the SSL encryption algorithms used for secure connections. GaussDB Kernel supports the following algorithms: - DHE-RSA-AES128-GCM-SHA256 - DHE-RSA-AES256-GCM-SHA384 - DHE-RSA-AES128-CCM - DHE-RSA-AES256-CCM You are advised to set sslciphers to ALL. Then, GaussDB Kernel uses...

In-band Protocol Negotiation And Robustness Weakness

aws-encryption-sdk suffers from an In-band protocol negotiation and robustness weakness. The SDK allows a unique ciphertext to be decrypted into different results due to the non-committing property of AES-GCM, and other AEAD ciphers such as AES-GCM-SIV, or XChaCha20Poly1305, when encrypting...
