affected by multiple vulnerabilities.");

"The version of Oracle (formerly Sun) Java SE or Java for Business
installed on the remote host is prior to 10 Update 2, 8 Update 181,
7 Update 191, or 6 Update 201. It is, therefore, affected by
multiple vulnerabilities related to the following components :

  - Concurrency. A difficult to exploit vulnerability allows
    an unauthenticated attacker with network access via
    multiple protocols to compromise Java SE (CVE-2018-2952)

  - Deployment. A difficult to exploit vulnerability allows
    an unauthenticated attacker with network access via
    multiple protocols to compromise Java SE (CVE-2018-2964)

  - JSSE. A difficult to exploit vulnerability allows
    an unauthenticated attacker with network access via
    multiple protocols to compromise Java SE (CVE-2018-2973)

  - Java DB. A difficult to exploit vulnerability allows an
    unauthenticated attacker with network access via
    multiple protocols to compromise Java SE. (CVE-2018-2938)

  - JavaFX. A difficult to exploit vulnerability allows an
    unauthenticated attacker with network access via
    multiple protocols to compromise Java SE. (CVE-2018-2941)

  - Libraries. An easily exploitable vulnerability allows
    an unauthenticated attacker with network access via
    multiple protocols to compromise Java SE. (CVE-2018-2940)

  - Security. A difficult to exploit vulnerability allows
    an unauthenticated attacker with network access via
    multiple protocols to compromise Java SE (CVE-2018-2972)

  - Windows DLL. A difficult to exploit vulnerability allows
    an unauthenticated attacker with network access via
    multiple protocols to compromise Java SE (CVE-2018-2942)

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