| Package | Affected versions | Patched versions |
|---|---|---|
| unrealircd | ≥ 6.1.0, < 6.1.4 | 6.1.4 |
A buffer overflow in websockets in UnrealIRCd 6.1.0 through 6.1.3 before 6.1.4 allows an unauthenticated remote attacker to crash the server by sending an oversized packet (if a websocket port is open). Remote code execution might be possible on some uncommon, older platforms.
