"The version of Apple iTunes installed on the remote Windows host is
prior to 12.4.2. It is, therefore, affected by multiple
vulnerabilities :

  - Multiple memory corruption issues exist in the libxslt
    component due to improper validation of user-supplied
    input. An unauthenticated, remote attacker can exploit
    this to cause a denial of service condition or the
    execution of arbitrary code. (CVE-2016-1684,
    CVE-2016-4607, CVE-2016-4608, CVE-2016-4609,
    CVE-2016-4610, CVE-2016-4612)

  - Multiple memory corruption issues exist in the libxml2
    component that allow a remote attacker to cause a denial
    of service condition or the execution of arbitrary code.
    (CVE-2016-1836, CVE-2016-4447, CVE-2016-4448,
    CVE-2016-4483, CVE-2016-4614, CVE-2016-4615,
    CVE-2016-4616, CVE-2016-4619)

  - An XXE (Xml eXternal Entity) injection vulnerability
    exists in the libxml2 component due to an incorrectly
    configured XML parser accepting XML external entities
    from an untrusted source. A remote attacker can exploit
    this, via a specially crafted XML file, to disclose
    arbitrary files and user information. (CVE-2016-4449)

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