| summary: Authentication failure in mellium.im/sasl |
| description: |- |
| An issue was discovered in Mellium mellium.im/sasl before 0.3.1. When performing |
| SCRAM-based SASL authentication, if the remote end advertises support for |
| channel binding, no random nonce is generated (instead, the nonce is empty). |
| This causes authentication to fail in the best case, but (if paired with a |
| remote end that does not validate the length of the nonce) could lead to |
| insufficient randomness being used during authentication. |
