  - Multiple information disclosure vulnerabilities exist

    unauthenticated, remote attacker can exploit these
    vulnerabilities by convincing a user to open a specially
    crafted .pdf file, resulting in the disclosure of
    sensitive information in the context of the current
    user. (CVE-2016-3201, CVE-2016-3215)

  - A remote code execution vulnerability exists due to
    improper parsing of .pdf files. An unauthenticated,
    remote attacker can exploit this vulnerability by
    convincing a user to open a specially crafted .pdf file,
    resulting in the execution of arbitrary code in the
    context of the current user. (CVE-2016-3203)");
