  - Vulnerability in the Java SE, Java SE Embedded, JRockit component of Oracle Java SE (subcomponent:
    Libraries). Supported versions that are affected are Java SE: 6u171, 7u161, 8u152 and 9.0.1; Java SE
    Embedded: 8u151; JRockit: R28.3.16. Easily exploitable vulnerability allows unauthenticated attacker with
    network access via multiple protocols to compromise Java SE, Java SE Embedded, JRockit. 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, JRockit. Note: This vulnerability applies to client and server deployment of Java. This
    vulnerability can be exploited through sandboxed Java Web Start applications and sandboxed Java applets.
    It can also be exploited by supplying data to APIs in the specified Component without using sandboxed Java
    Web Start applications or sandboxed Java applets, such as through a web service. (CVE-2018-2663)

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