  - Vulnerability in the Java SE, Java SE Embedded, JRockit component of Oracle Java SE (subcomponent:
    Concurrency). Supported versions that are affected are Java SE: 6u191, 7u181, 8u172 and 10.0.1; Java SE
    Embedded: 8u171; JRockit: R28.3.18. Difficult to exploit vulnerability allows unauthenticated attacker
    with network access via multiple protocols to compromise Java SE, Java SE Embedded, JRockit. 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: 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-2018-2952)
