| Doc Text: |
A flaw was found in the Netty HAProxy PROXY protocol v2 codec. A remote attacker can exploit this vulnerability by sending a specially crafted HAProxy PROXY protocol v2 header with nested `PP2_TYPE_SSL` type-length-value (TLV) records. This can lead to a memory leak, causing the underlying cumulation buffer to remain permanently pinned and potentially resulting in a Denial of Service (DoS) due to resource exhaustion.
