"The version of java-11-amazon-corretto installed on the remote host is prior to 11.0.21+9-1. It is, therefore, affected
by a vulnerability as referenced in the ALAS2-2023-2315 advisory.

  - Vulnerability in the Oracle Java SE, Oracle GraalVM for JDK product of Oracle Java SE (component: JSSE).
    Supported versions that are affected are Oracle Java SE: 8u381, 8u381-perf, 11.0.20, 17.0.8, 20.0.2;
    Oracle GraalVM for JDK: 17.0.8 and 20.0.2. Easily exploitable vulnerability allows unauthenticated
    attacker with network access via HTTPS to compromise Oracle Java SE, Oracle GraalVM for JDK. 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 for JDK. 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 does not apply to Java deployments, typically in servers, that load and
    run only trusted code (e.g., code installed by an administrator). (CVE-2023-22081)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
