CVE-2016-9121 Information

Description

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 it vulnerable to an invalid curve attack.
