"The version of Adobe Flash Player installed on the remote macOS or Mac
OS X host is equal or prior to version 26.0.0.137. It is, therefore,
affected by multiple vulnerabilities :

  - An information disclosure vulnerability exists due to an
    unspecified flaw. An unauthenticated, remote attacker
    can exploit this, by convincing a user to visit a
    website containing specially crafted Flash content, to
    disclose sensitive information. (CVE-2017-3085)

  - A remote code execution vulnerability exists due to
    improper validation of user-supplied input. An
    unauthenticated, remote attacker can exploit this, by
    convincing a user to visit a website containing
    specially crafted Flash content, to execute arbitrary
    code. (CVE-2017-3106)");
