20 Aug 2017 — Nimbus JOSE+JWT before 4.36 proceeds with ECKey construction without ensuring that the public x and y coordinates are on the specified curve, which allows attackers to conduct an Invalid Curve Attack in environments where the JCE provider lacks the applicable curve validation. Nimbus JOSE+JWT en versiones anteriores a la 4.36 procede con la construcción ECKey sin asegurarse de que las coordenadas públicas x e y están en la curva especificada. Esto permite que los atacantes lleven a cabo un ataque de curva n... • https://bitbucket.org/connect2id/nimbus-jose-jwt/commits/f3a7a801f0c6b078899fed9226368eb7b44e2b2f • CWE-347: Improper Verification of Cryptographic Signature •

20 Aug 2017 — Nimbus JOSE+JWT before 4.39 proceeds improperly after detection of an invalid HMAC in authenticated AES-CBC decryption, which allows attackers to conduct a padding oracle attack. Nimbus JOSE+JWT en versiones anteriores a la 4.39 procede de forma inadecuada tras detectar un HMAC no válido en un descifrado AES-CBC, lo que permite que atacantes lleven a cabo un ataque padding oracle. • https://bitbucket.org/connect2id/nimbus-jose-jwt/commits/6a29f10f723f406eb25555f55842c59a43a38912 • CWE-354: Improper Validation of Integrity Check Value •

20 Aug 2017 — In Nimbus JOSE+JWT before 4.39, there is no integer-overflow check when converting length values from bytes to bits, which allows attackers to conduct HMAC bypass attacks by shifting Additional Authenticated Data (AAD) and ciphertext so that different plaintext is obtained for the same HMAC. En Nimbus JOSE+JWT en versiones anteriores a la 4.39 no hay comprobación de desbordamiento de enteros al convertir valores de longitud de bytes a bits, lo que permite que atacantes lleven a cabo ataques de omisión HMAC ... • https://bitbucket.org/connect2id/nimbus-jose-jwt/commits/0d2bd649ea386539220d4facfe1f65eb1dadb86c • CWE-345: Insufficient Verification of Data Authenticity •
