CVE-2016-9121

go-jose before 1.0.4 suffers from an invalid curve attack for the ECDH-ES algorithm. When deriving a shared key using ECDH-ES for an encrypted message, go-jose neglected to check that the received public key on a message is on the same curve as the static private key of the receiver, thus making ...

CVE-2016-9121

CVE-2016-9121 affects square/go-jose prior to version 1.0.4, where ECDH-ES shared-key derivation neglects to verify that the received public key lies on the same elliptic curve as the receiver’s private key. This enables an invalid-curve attack during decryption and is stated across multiple sour...

CVE-2016-9121: Inadequate Encryption Strength

go-jose before 1.0.4 suffers from an invalid curve attack for the ECDH-ES algorithm. When deriving a shared key using ECDH-ES for an encrypted message, go-jose neglected to check that the received public key on a message is on the same curve as the static private key of the receiver, thus making ...

JSON Libraries Patched Against Invalid Curve Crypto Attack

A number of JSON libraries using the JSON Web Encryption specification JWE to create, sign and encrypt access tokens have been patched against an attack that allows for the recovery of a private key. Researcher Antonio Sanso of Adobe said the go-jose, node-jose, jose2go, Nimbus JOSE+WT and jose4...

Invalid Curve Attack

node-jose, nimbus-jose-jwt and jose4j are vulnerable to invalid curve attacks. These attacks are possible when using key agreement with Elliptic Curve Diffie-Hellman Ephemeral Static ECDH-ES, allowing attackers to recover the private secret key...

Invalid Curve Attack

Overview Affected versions of node-jose are vulnerable to an invalid curve attack. This allows an attacker to recover the private secret key when JWE with Key Agreement with Elliptic Curve Diffie-Hellman Ephemeral Static ECDH-ES is used. Proof of Concept Recommendation Update to version 0.9.3 or...

Critical vulnerability in JSON Web Encryption (JWE) - RFC 7516

tl;dr if you are using go-jose, node-jose, jose2go, Nimbus JOSE+JWT or jose4j with ECDH-ES please update to the latest version. RFC 7516 aka JSON Web Encryption JWE hence many software libraries implementing this specification used to suffer from a classic Invalid Curve Attack. This would allow a...
