netty-codec-haproxy: Netty-codec-haproxy: Denial of Service via malformed HAProxy message

A flaw was found in netty-codec-haproxy, a component of the Netty network application framework. A remote attacker can exploit this vulnerability by sending a specially crafted HAProxy message with a malformed PP2TYPESSL TLV Type-Length-Value header. This can lead to an IndexOutOfBoundsException...

CVE-2026-48059 Netty HAProxy: Unbalanced Reference Count in Nested PP2_TYPE_SSL TLV Parsing Leads to Memory Exhaustion

Netty is a network application framework for development of protocol servers and clients. Prior to versions 4.1.135.Final and 4.2.15.Final, the HAProxy PROXY protocol v2 codec in netty leaks native or heap memory on every connection when a client sends a syntactically valid header containing nest...

CLDAP Analyzer with ASN.1 BER Encoding and Basic TLV Response Parser

This Python script implements a CLDAP Connectionless LDAP analyzer that builds and sends LDAP CLDAP discovery requests and parses responses using ASN.1 BER encoding and a basic TLV parser. It constructs a structured LDAP search request including DnsDomain, User, and NtVer filters, sends it over U...

GHSA-CC37-9Q2J-3HFV Netty: HAProxy SSL TLV parsing leaks retained slice on invalid TLV length

When decoding a PP2TYPESSL TLV, HAProxyMessage.readNextTLV first calls header.retainedSliceheader.readerIndex, length and only then reads the 1-byte client field and 4-byte verify field. If the attacker sets the TLV length below 5, the subsequent readByte/readInt throws IndexOutOfBoundsException...
