  - Vulnerability in the Oracle Java SE, Oracle GraalVM Enterprise Edition product of Oracle Java SE
    (component: JAXP). Supported versions that are affected are Oracle Java SE: 7u331, 8u321, 11.0.14, 17.0.2,
    18; Oracle GraalVM Enterprise Edition: 20.3.5, 21.3.1 and 22.0.0.2. Easily exploitable vulnerability
    allows unauthenticated attacker with network access via multiple protocols to compromise Oracle Java SE,
    Oracle GraalVM Enterprise Edition. Successful attacks of this vulnerability can result in unauthorized
    ability to cause a partial denial of service (partial DOS) of Oracle Java SE, Oracle GraalVM Enterprise
    Edition. Note: This vulnerability applies to Java deployments, typically in clients running sandboxed Java
    Web Start applications or sandboxed Java applets, 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-2022-21426)

Note that Nessus relies on the presence of the package as reported by the vendor.");
