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 ...
PYSEC-2020-142
A mis-handling of invalid unicode characters in the Java implementation of Tink versions prior to 1.5 allows an attacker to change the ID part of a ciphertext, which result in the creation of a second ciphertext that can decrypt to the same plaintext. This can be a problem with encrypting...

NaCl Is Not a High-Level API
When talking about high-level application cryptography APIs I usually hear mentioned libsodium, Tink, pyca/cryptography, and NaCl. One of these things is not like the others! The value NaCl had 10 years ago was that it was an opinionated library at a time when all cryptography libraries were...
FreeBSD : gnupg -- AEAD key import overflow (f9fa7adc-ee51-11ea-a240-002590acae31)
Importing an OpenPGP key having a preference list for AEAD algorithms will lead to an array overflow and thus often to a crash or other undefined behaviour. Importing an arbitrary key can often easily be triggered by an attacker and thus triggering this bug. Exploiting the bug aside from crashes ...
CVE-2020-25125
GnuPG 2.2.21 and 2.2.22 and Gpg4win 3.1.12 has an array overflow, leading to a crash or possibly unspecified other impact, when a victim imports an attacker's OpenPGP key, and this key has AEAD preferences. The overflow is caused by a g10/key-check.c error. NOTE: GnuPG 2.3.x is unaffected. GnuPG...
