patched.");

"The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied
patch available.

  - Vulnerability in the Java SE, Java SE Embedded component of Oracle Java SE (subcomponent: AWT). Supported
    versions that are affected are Java SE: 6u171, 7u161, 8u152 and 9.0.1; Java SE Embedded: 8u151. Easily
    exploitable vulnerability allows unauthenticated attacker with network access via multiple protocols to
    compromise Java SE, Java SE Embedded. Successful attacks require human interaction from a person other
    than the attacker. Successful attacks of this vulnerability can result in unauthorized ability to cause a
    partial denial of service (partial DOS) of Java SE, Java SE Embedded. 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-2018-2677)

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