| CVE-2026-44248 | Med | 0.27 | 5.3 | 0.00 | May 13, 2026 | Netty is an asynchronous, event-driven network application framework. Prior to 4.2.13.Final and 4.1.133.Final, the MQTT 5 header Properties section is parsed and buffered before any message size limit is applied. Specifically, in MqttDecoder, the decodeVariableHeader() method is… | ||
| CVE-2026-45536 | Med | 0.26 | 4.0 | 0.00 | Jun 12, 2026 | 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, netty_unix_socket_recvFd sets msg_control to `char control[CMSG_SPACE(sizeof(int))]` (line 940) — 24 bytes on 64-bit Linux. A peer-sent… | ||
| CVE-2020-11612 | Hig | 0.01 | 7.5 | 0.09 | Apr 7, 2020 | The ZlibDecoders in Netty 4.1.x before 4.1.46 allow for unbounded memory allocation while decoding a ZlibEncoded byte stream. An attacker could send a large ZlibEncoded byte stream to the Netty server, forcing the server to allocate all of its free memory to a single decoder. | ||
| CVE-2019-20445 | Cri | 0.01 | 9.1 | 0.13 | Jan 29, 2020 | HttpObjectDecoder.java in Netty before 4.1.44 allows a Content-Length header to be accompanied by a second Content-Length header, or by a Transfer-Encoding header. | ||
| CVE-2019-20444 | Cri | 0.01 | 9.1 | 0.09 | Jan 29, 2020 | HttpObjectDecoder.java in Netty before 4.1.44 allows an HTTP header that lacks a colon, which might be interpreted as a separate header with an incorrect syntax, or might be interpreted as an "invalid fold." | ||
| CVE-2020-7238 | Hig | 0.00 | 7.5 | 0.04 | Jan 27, 2020 | Netty 4.1.43.Final allows HTTP Request Smuggling because it mishandles Transfer-Encoding whitespace (such as a [space]Transfer-Encoding:chunked line) and a later Content-Length header. This issue exists because of an incomplete fix for CVE-2019-16869. | ||
| CVE-2014-3488 | 0.00 | — | 0.04 | Jul 31, 2014 | The SslHandler in Netty before 3.9.2 allows remote attackers to cause a denial of service (infinite loop and CPU consumption) via a crafted SSLv2Hello message. | |||
