| Package | Affected versions | Patched versions |
|---|---|---|
| multibit hd | < 0.1.2 | 0.1.2 |
MultiBit HD before 0.1.2 allows attackers to conduct bit-flipping attacks that insert unspendable Bitcoin addresses into the list that MultiBit uses to send fees to the developers. (Attackers cannot realistically steal these fees for themselves.) This occurs because there is no message authentication code (MAC).
