  - Vulnerability in the Java SE, Java SE Embedded, JRockit component of Oracle Java SE (subcomponent: JNDI).
    Supported versions that are affected are Java SE: 6u171, 7u161, 8u152 and 9.0.1; Java SE Embedded: 8u151;
    JRockit: R28.3.16. Difficult to exploit 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 and while the vulnerability is in Java SE, Java SE
    Embedded, JRockit, attacks may significantly impact additional products. Successful attacks of this
    vulnerability can result in takeover 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-2018-2633)

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