| Description | HAProxy PROXY-v2 nested-TLV grandchild ByteBuf reference-count leak (incomplete fix of PR #16881) | A flaw was found in Netty. A reference-count leak in the HAProxy PROXY-v2 message decoder allows a remote, unauthenticated attacker to send specially crafted PROXY-protocol v2 headers. This can lead to memory exhaustion, resulting in a Denial of Service (DoS) for the affected system. |
