| Package | Affected versions | Patched versions |
|---|---|---|
| wolfssl | ≥ 5.0.0, < 5.1.1 | 5.1.1 |
wolfSSL 5.x before 5.1.1 uses non-random IV values in certain situations. This affects connections (without AEAD) using AES-CBC or DES3 with TLS 1.1 or 1.2 or DTLS 1.1 or 1.2. This occurs because of misplaced memory initialization in BuildMessage in internal.c.
