Several vulnerabilities have been discovered in netty, a Java NIO client/server socket framework.

CVE-2019-20444

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-2019-20445

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-2020-7238

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-2020-11612

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.

For Debian 9 stretch, these problems have been fixed in version 1:4.1.7-2+deb9u2.

We recommend that you upgrade your netty packages.

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the 53caf29b-9180-11ed-acbe-b42e991fc52e advisory.

  - Vulnerability in the Java SE, Java SE Embedded component of Oracle Java SE (subcomponent: RMI). Supported     versions that are affected are Java SE: 7u211, 8u202, 11.0.2 and 12; Java SE Embedded: 8u201. Difficult to     exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to     compromise Java SE, Java SE Embedded. Successful attacks of this vulnerability can result in unauthorized     creation, deletion or modification access to critical data or all Java SE, Java SE Embedded accessible     data. Note: This vulnerability applies to Java deployments, typically in clients running sandboxed Java     Web Start applications or sandboxed Java applets (in Java SE 8), that load and run untrusted code (e.g.,     code that comes from the internet) and rely on the Java sandbox for security. This vulnerability can also     be exploited by using APIs in the specified Component, e.g., through a web service which supplies data to     the APIs. (CVE-2019-2684)

  - 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-2020-7238)

  - 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-2022-24823)

  - The package org.yaml:snakeyaml from 0 and before 1.31 are vulnerable to Denial of Service (DoS) due     missing to nested depth limitation for collections. (CVE-2022-25857)

  - In FasterXML jackson-databind before 2.14.0-rc1, resource exhaustion can occur because of a lack of a     check in primitive value deserializers to avoid deep wrapper array nesting, when the     UNWRAP_SINGLE_VALUE_ARRAYS feature is enabled. Additional fix version in 2.13.4.1 and 2.12.17.1     (CVE-2022-42003)

  - In FasterXML jackson-databind before 2.13.4, resource exhaustion can occur because of a lack of a check in     BeanDeserializer._deserializeFromArray to prevent use of deeply nested arrays. An application is     vulnerable only with certain customized choices for deserialization. (CVE-2022-42004)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
