| CVE-2025-58056 | 1 Netty | 1 Netty | 2025-09-08 | N/A | 7.5 HIGH |
| Netty is an asynchronous event-driven network application framework for development of maintainable high performance protocol servers and clients. In versions 4.1.124.Final, and 4.2.0.Alpha3 through 4.2.4.Final, Netty incorrectly accepts standalone newline characters (LF) as a chunk-size line terminator, regardless of a preceding carriage return (CR), instead of requiring CRLF per HTTP/1.1 standards. When combined with reverse proxies that parse LF differently (treating it as part of the chunk extension), attackers can craft requests that the proxy sees as one request but Netty processes as two, enabling request smuggling attacks. This is fixed in versions 4.1.125.Final and 4.2.5.Final. | |||||
| CVE-2025-58057 | 1 Netty | 1 Netty | 2025-09-08 | N/A | 7.5 HIGH |
| Netty is an asynchronous event-driven network application framework for rapid development of maintainable high performance protocol servers & clients. In netty-codec-compression versions 4.1.124.Final and below, and netty-codec versions 4.2.4.Final and below, when supplied with specially crafted input, BrotliDecoder and certain other decompression decoders will allocate a large number of reachable byte buffers, which can lead to denial of service. BrotliDecoder.decompress has no limit in how often it calls pull, decompressing data 64K bytes at a time. The buffers are saved in the output list, and remain reachable until OOM is hit. This is fixed in versions 4.1.125.Final of netty-codec and 4.2.5.Final of netty-codec-compression. | |||||
| CVE-2025-24970 | 2 Netapp, Netty | 3 Active Iq Unified Manager, Oncommand Insight, Netty | 2025-09-05 | N/A | 7.5 HIGH |
| Netty, an asynchronous, event-driven network application framework, has a vulnerability starting in version 4.1.91.Final and prior to version 4.1.118.Final. When a special crafted packet is received via SslHandler it doesn't correctly handle validation of such a packet in all cases which can lead to a native crash. Version 4.1.118.Final contains a patch. As workaround its possible to either disable the usage of the native SSLEngine or change the code manually. | |||||
| CVE-2024-47535 | 2 Microsoft, Netty | 2 Windows, Netty | 2025-09-05 | N/A | 5.5 MEDIUM |
| Netty is an asynchronous event-driven network application framework for rapid development of maintainable high performance protocol servers & clients. An unsafe reading of environment file could potentially cause a denial of service in Netty. When loaded on an Windows application, Netty attempts to load a file that does not exist. If an attacker creates such a large file, the Netty application crashes. This vulnerability is fixed in 4.1.115. | |||||
| CVE-2019-16869 | 4 Canonical, Debian, Netty and 1 more | 5 Ubuntu Linux, Debian Linux, Netty and 2 more | 2025-07-07 | 5.0 MEDIUM | 7.5 HIGH |
| Netty before 4.1.42.Final mishandles whitespace before the colon in HTTP headers (such as a "Transfer-Encoding : chunked" line), which leads to HTTP request smuggling. | |||||
| CVE-2019-20444 | 5 Canonical, Debian, Fedoraproject and 2 more | 7 Ubuntu Linux, Debian Linux, Fedora and 4 more | 2025-07-01 | 6.4 MEDIUM | 9.1 CRITICAL |
| 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-2023-44487 | 32 Akka, Amazon, Apache and 29 more | 313 Http Server, Opensearch Data Prepper, Apisix and 310 more | 2025-06-11 | N/A | 7.5 HIGH |
| The HTTP/2 protocol allows a denial of service (server resource consumption) because request cancellation can reset many streams quickly, as exploited in the wild in August through October 2023. | |||||
| CVE-2025-25193 | 2 Microsoft, Netty | 2 Windows, Netty | 2025-06-11 | N/A | 5.5 MEDIUM |
| Netty, an asynchronous, event-driven network application framework, has a vulnerability in versions up to and including 4.1.118.Final. An unsafe reading of environment file could potentially cause a denial of service in Netty. When loaded on an Windows application, Netty attempts to load a file that does not exist. If an attacker creates such a large file, the Netty application crash. A similar issue was previously reported as CVE-2024-47535. This issue was fixed, but the fix was incomplete in that null-bytes were not counted against the input limit. Commit d1fbda62d3a47835d3fb35db8bd42ecc205a5386 contains an updated fix. | |||||
| CVE-2015-2156 | 3 Lightbend, Netty, Playframework | 3 Play Framework, Netty, Play Framework | 2025-04-20 | 4.3 MEDIUM | 7.5 HIGH |
| Netty before 3.9.8.Final, 3.10.x before 3.10.3.Final, 4.0.x before 4.0.28.Final, and 4.1.x before 4.1.0.Beta5 and Play Framework 2.x before 2.3.9 might allow remote attackers to bypass the httpOnly flag on cookies and obtain sensitive information by leveraging improper validation of cookie name and value characters. | |||||
| CVE-2016-4970 | 3 Apache, Netty, Redhat | 4 Cassandra, Netty, Jboss Data Grid and 1 more | 2025-04-20 | 7.8 HIGH | 7.5 HIGH |
| handler/ssl/OpenSslEngine.java in Netty 4.0.x before 4.0.37.Final and 4.1.x before 4.1.1.Final allows remote attackers to cause a denial of service (infinite loop). | |||||
| CVE-2014-3488 | 1 Netty | 1 Netty | 2025-04-12 | 5.0 MEDIUM | N/A |
| 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. | |||||
| CVE-2014-0193 | 1 Netty | 1 Netty | 2025-04-12 | 5.0 MEDIUM | N/A |
| WebSocket08FrameDecoder in Netty 3.6.x before 3.6.9, 3.7.x before 3.7.1, 3.8.x before 3.8.2, 3.9.x before 3.9.1, and 4.0.x before 4.0.19 allows remote attackers to cause a denial of service (memory consumption) via a TextWebSocketFrame followed by a long stream of ContinuationWebSocketFrames. | |||||
| CVE-2023-34462 | 1 Netty | 1 Netty | 2024-11-21 | N/A | 6.5 MEDIUM |
| Netty is an asynchronous event-driven network application framework for rapid development of maintainable high performance protocol servers & clients. The `SniHandler` can allocate up to 16MB of heap for each channel during the TLS handshake. When the handler or the channel does not have an idle timeout, it can be used to make a TCP server using the `SniHandler` to allocate 16MB of heap. The `SniHandler` class is a handler that waits for the TLS handshake to configure a `SslHandler` according to the indicated server name by the `ClientHello` record. For this matter it allocates a `ByteBuf` using the value defined in the `ClientHello` record. Normally the value of the packet should be smaller than the handshake packet but there are not checks done here and the way the code is written, it is possible to craft a packet that makes the `SslClientHelloHandler`. This vulnerability has been fixed in version 4.1.94.Final. | |||||
| CVE-2022-41915 | 2 Debian, Netty | 2 Debian Linux, Netty | 2024-11-21 | N/A | 6.5 MEDIUM |
| Netty project is an event-driven asynchronous network application framework. Starting in version 4.1.83.Final and prior to 4.1.86.Final, when calling `DefaultHttpHeadesr.set` with an _iterator_ of values, header value validation was not performed, allowing malicious header values in the iterator to perform HTTP Response Splitting. This issue has been patched in version 4.1.86.Final. Integrators can work around the issue by changing the `DefaultHttpHeaders.set(CharSequence, Iterator<?>)` call, into a `remove()` call, and call `add()` in a loop over the iterator of values. | |||||
| CVE-2022-41881 | 2 Debian, Netty | 2 Debian Linux, Netty | 2024-11-21 | N/A | 5.3 MEDIUM |
| Netty project is an event-driven asynchronous network application framework. In versions prior to 4.1.86.Final, a StackOverflowError can be raised when parsing a malformed crafted message due to an infinite recursion. This issue is patched in version 4.1.86.Final. There is no workaround, except using a custom HaProxyMessageDecoder. | |||||
| CVE-2022-24823 | 3 Netapp, Netty, Oracle | 5 Active Iq Unified Manager, Oncommand Workflow Automation, Snapcenter and 2 more | 2024-11-21 | 1.9 LOW | 5.5 MEDIUM |
| Netty is an open-source, asynchronous event-driven network application framework. The package `io.netty:netty-codec-http` prior to version 4.1.77.Final contains an insufficient fix for CVE-2021-21290. When Netty's multipart decoders are used local information disclosure can occur via the local system temporary directory if temporary storing uploads on the disk is enabled. This only impacts applications running on Java version 6 and lower. Additionally, this vulnerability impacts code running on Unix-like systems, and very old versions of Mac OSX and Windows as they all share the system temporary directory between all users. Version 4.1.77.Final contains a patch for this vulnerability. As a workaround, specify one's own `java.io.tmpdir` when starting the JVM or use DefaultHttpDataFactory.setBaseDir(...) to set the directory to something that is only readable by the current user. | |||||
| CVE-2021-43797 | 5 Debian, Netapp, Netty and 2 more | 18 Debian Linux, Oncommand Workflow Automation, Snapcenter and 15 more | 2024-11-21 | 4.3 MEDIUM | 6.5 MEDIUM |
| Netty is an asynchronous event-driven network application framework for rapid development of maintainable high performance protocol servers & clients. Netty prior to version 4.1.71.Final skips control chars when they are present at the beginning / end of the header name. It should instead fail fast as these are not allowed by the spec and could lead to HTTP request smuggling. Failing to do the validation might cause netty to "sanitize" header names before it forward these to another remote system when used as proxy. This remote system can't see the invalid usage anymore, and therefore does not do the validation itself. Users should upgrade to version 4.1.71.Final. | |||||
| CVE-2021-37137 | 5 Debian, Netapp, Netty and 2 more | 12 Debian Linux, Oncommand Insight, Netty and 9 more | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
| The Snappy frame decoder function doesn't restrict the chunk length which may lead to excessive memory usage. Beside this it also may buffer reserved skippable chunks until the whole chunk was received which may lead to excessive memory usage as well. This vulnerability can be triggered by supplying malicious input that decompresses to a very big size (via a network stream or a file) or by sending a huge skippable chunk. | |||||
| CVE-2021-37136 | 5 Debian, Netapp, Netty and 2 more | 19 Debian Linux, Oncommand Insight, Netty and 16 more | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
| The Bzip2 decompression decoder function doesn't allow setting size restrictions on the decompressed output data (which affects the allocation size used during decompression). All users of Bzip2Decoder are affected. The malicious input can trigger an OOME and so a DoS attack | |||||
| CVE-2021-21409 | 5 Debian, Netapp, Netty and 2 more | 18 Debian Linux, Oncommand Api Services, Oncommand Workflow Automation and 15 more | 2024-11-21 | 4.3 MEDIUM | 5.9 MEDIUM |
| Netty is an open-source, asynchronous event-driven network application framework for rapid development of maintainable high performance protocol servers & clients. In Netty (io.netty:netty-codec-http2) before version 4.1.61.Final there is a vulnerability that enables request smuggling. The content-length header is not correctly validated if the request only uses a single Http2HeaderFrame with the endStream set to to true. This could lead to request smuggling if the request is proxied to a remote peer and translated to HTTP/1.1. This is a followup of GHSA-wm47-8v5p-wjpj/CVE-2021-21295 which did miss to fix this one case. This was fixed as part of 4.1.61.Final. | |||||
