CVE-2016-9121 WRITEUP CRITICAL WRITEUP
go-jose < 1.0.4 - Inadequate Encryption Strength via ECDH-ES Invalid Curve Attack
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.
CVSS 9.1
CVE-2016-9122 WRITEUP HIGH WRITEUP
go-jose < 1.0.4 - Improper Access Control via Multiple Signature Handling
go-jose before 1.0.4 suffers from multiple signatures exploitation. The go-jose library supports messages with multiple signatures. However, when validating a signed message the API did not indicate which signature was valid, which could potentially lead to confusion. For example, users of the library might mistakenly read protected header values from an attached signature that was different from the one originally validated.
CVSS 7.5
CVE-2016-9123 WRITEUP HIGH WRITEUP
go-jose <1.0.5 - Privilege Escalation
go-jose before 1.0.5 suffers from a CBC-HMAC integer overflow on 32-bit architectures. An integer overflow could lead to authentication bypass for CBC-HMAC encrypted ciphertexts on 32-bit architectures.
