Improper Verification of Source of a Communication Channel

Overview Affected versions of this package are vulnerable to Improper Verification of Source of a Communication Channel due to improper validation in the validateToken function. An attacker can cause the server to treat unvalidated client addresses as validated by supplying any non-empty token...

Missing Release of Resource after Effective Lifetime

Overview Affected versions of this package are vulnerable to Missing Release of Resource after Effective Lifetime through improper handling of TLV length in the readNextTLV function. An attacker can cause resource exhaustion and denial of service by sending a specially crafted HAProxy protocol...

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...
