CVE-2016-9123
HighSummary
The go-jose library before version 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 these architectures.
Risk Assessment
Organizations may be exposed to attacks that allow authentication bypass, potentially leading to unauthorized access to data.
Recommendation
It is recommended to update the go-jose library to version 1.0.5 or later to mitigate this vulnerability.
Other vulnerabilities in go-jose
See all- CVE-2016-9121Critical
The go-jose library before version 1.0.4 is vulnerable to an invalid curve attack in the ECDH-ES algorithm. When deriving a shared key, go-jose fails to check that the received public key is on the same curve as the receiver's static private key.
- CVE-2026-34986High
Go JOSE prior to versions 4.1.4 and 3.0.5 has a vulnerability where decrypting a JWE object can panic if the alg field indicates a key wrapping algorithm (ending in KW, except A128GCMKW, A192GCMKW, A256GCMKW) and the encrypted_key field is empty. The panic occurs when attempting to allocate a slice with zero or negative length. This can lead to denial of service.
