CVE-2016-9121
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.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.41%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
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.
