"The version of Firefox installed on the remote Mac OS X host is prior
to 46. It is, therefore, affected by multiple vulnerabilities :

  - Multiple memory corruption issues exist that allow an
    attacker to corrupt memory, resulting in the execution
    of arbitrary code. (CVE-2016-2804, CVE-2016-2806,
    CVE-2016-2807)

  - A flaw exists due to improper validation of
    user-supplied input when handling the 32-bit generation
    count of the underlying HashMap. A context-dependent
    attacker can exploit this to cause a buffer overflow
    condition, resulting in a denial of service or the
    execution of arbitrary code. (CVE-2016-2808)

  - A remote code execution vulnerability exists due to a
    use-after-free error in the BeginReading() function. A
    context-dependent attacker can exploit this to
    dereference already freed memory, resulting in the
    execution of arbitrary code. (CVE-2016-2811)

  - A remote code execution vulnerability exists due to a
    race condition in ServiceWorkerManager in the get()
    function. A context-dependent attacker can exploit this
    to execute arbitrary code. (CVE-2016-2812)

  - A heap buffer overflow condition exists in the Google
    Stagefright component due to improper validation of
    user-supplied input when handling CENC offsets and the
    sizes table. A context-dependent attacker can exploit
    this to cause a denial of service condition or the
    execution of arbitrary code. (CVE-2016-2814)

  - A security bypass vulnerability exists due to the
    Content Security Policy (CSP) not being properly applied
    to web content sent with the 'multipart/x-mixed-replace'
    MIME-type. A context-dependent attacker can exploit this
    to bypass CSP protection. (CVE-2016-2816)

  - A cross-site scripting (XSS) vulnerability exists due to
    improper restriction of unprivileged 'javascript: URL'
    navigation. A context-dependent attacker can exploit
    this, via a specially crafted request, to execute
    arbitrary script code in the context of a user's browser
    session. (CVE-2016-2817)

  - A flaw exists in the Firefox Health Report that is
    triggered when it accepts any content document events
    that are presented in its iframe. A context-dependent
    attacker can exploit this to manipulate sharing
    preferences. (CVE-2016-2820)");
