Description ybuenos 2023-12-17 11:17:25 UTC 
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.
