(CVE-2022-41881)

    It was discovered that Netty did not validate header values under certain circumstances. A remote attacker     could possibly use this issue to perform HTTP response splitting via malicious header values. This issue     only affected Ubuntu 18.04 ESM, Ubuntu 20.04 ESM, Ubuntu 22.04 LTS, and Ubuntu 22.10. (CVE-2022-41915)

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-017767 advisory.

    Netty is an open-source, asynchronous event-driven network application framework for rapid development of     maintainable high performance protocol servers & clients. In Netty before version 4.1.59.Final there is a     vulnerability on Unix-like systems involving an insecure temp file. 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. On unix-like systems, the temporary directory is shared between all user.
    As such, writing to this directory using APIs that do not explicitly set the file/directory permissions     can lead to information disclosure. Of note, this does not impact modern MacOS Operating Systems. The     method File.createTempFile on unix-like systems creates a random file, but, by default will create this     file with the permissions -rw-r--r--. Thus, if sensitive information is written to this file, other     local users can read this information. This is the case in netty's AbstractDiskHttpData is vulnerable.
    This has been fixed in version 4.1.59.Final. As a workaround, one may specify your own java.io.tmpdir     when you start the JVM or use DefaultHttpDataFactory.setBaseDir(...) to set the directory to something     that is only readable by the current user.

Successful attacks of this vulnerability can result in unauthorized read     access to a subset of Oracle NoSQL Database accessible data. (CVE-2020-8908)   
  - Vulnerability in Oracle NoSQL Database (component: Administration (Netty)). The supported version     that is affected is Prior to 20.3. Easily exploitable vulnerability allows unauthenticated attacker     with network access via HTTP to compromise Oracle NoSQL Database.
