Infinite loop

Overview Affected versions of this package are vulnerable to Infinite loop through the readFieldSection process. An attacker can cause the application to enter an infinite loop and exhaust CPU resources by sending a specially crafted Binary HTTP message with a manipulated field-section length,...

Allocation of Resources Without Limits or Throttling

Overview Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling due to the lack of enforced limits on variable length fields in the BinaryHttpParser. An attacker can exhaust system memory by sending specially crafted requests with excessively larg...

GHSA-HMQ9-67W8-J5PW netty-incubator-codec-ohttp: BinaryHttpParser should enforce limits for variable lengths fields

We don't enforce any limits for the encoded variable lengths that are used for fields. As the remote peer controls these it's easy for the remote peer to have us buffer data forever and so ultimately OOM...

Infinite loop

Overview Affected versions of this package are vulnerable to Infinite loop in the readFieldSection process. An attacker can cause the parsing thread to enter an infinite loop by sending a specially crafted Binary HTTP input where a known-length field section ends exactly after a complete field...

GHSA-8CFX-WX3Q-MH5Q netty-incubator-codec-ohttp: Binary HTTP parser infinite loop on known-length field section boundary

Summary io.netty.incubator:netty-incubator-codec-bhttp can enter a non-terminating parse loop when a known-length Binary HTTP field section ends exactly after a complete field line. A remote peer that can send Binary HTTP input to a Netty pipeline using BinaryHttpParser / BinaryHttpDecoder can us...

Incorrect Conversion between Numeric Types

Overview Affected versions of this package are vulnerable to Incorrect Conversion between Numeric Types in the BinaryHttpParser process. An attacker can cause the decoder to crash and disrupt service availability by sending a specially crafted Binary HTTP payload with large variable-length intege...

GHSA-PGRF-4654-3GQ8 netty-incubator-codec-ohttp: Binary HTTP parser unchecked varint length overflow causes decoder crash

Summary io.netty.incubator:netty-incubator-codec-bhttp uses attacker-controlled Binary HTTP variable-length integers as long values but accumulates them into int offsets. Large valid varint lengths wrap the internal offset negative, leading to unchecked ArrayIndexOutOfBoundsException /...

Insertion of Sensitive Information into Log File

Overview Affected versions of this package are vulnerable to Insertion of Sensitive Information into Log File in the toString process and exception message handling, where raw HPKE private key bytes are included in string representations and error messages. An attacker can obtain sensitive privat...

GHSA-2MC4-J865-9Q4R netty-incubator-codec-ohttp: BoringSSL HPKE private key bytes exposed through toString() and exception messages

Summary io.netty.incubator:netty-incubator-codec-ohttp-hpke-classes-boringssl exposes raw HPKE private key bytes in string representations and error messages. BoringSSLAsymmetricCipherKeyPair.toString includes the private-key parameter object, and BoringSSLAsymmetricKeyParameter.toString renders...

Improper Control of a Resource Through its Lifetime

Overview Affected versions of this package are vulnerable to Improper Control of a Resource Through its Lifetime in the OHttpServerCodec process. An attacker can cause a native direct memory leak by sending encrypted client requests with invalid AEAD tags, leading to resource exhaustion and...

GHSA-VMR9-J6WF-PMH2 netty-incubator-codec-ohttp: [OHttpServerCodec] Native Direct-Memory Leak on AEAD Decryption Failure Leads to Gateway Denial of Service

The netty-incubator-codec-ohttp library implements Oblivious HTTP OHTTP gateway and client functionality using Netty's ByteBuf memory management. When an OHTTP gateway processes encrypted client requests, it allocates a pooled direct native off-heap ByteBuf to hold the decrypted plaintext before...
