"The version of Mozilla Firefox installed on the remote Mac OS X host
is prior to 40.0.3. It is, therefore, affected by the following
vulnerabilities :

  - A use-after-free error exists when handling restyling
    operations during the resizing of canvas elements due to
    the canvas references being recreated, thus destroying
    the original references. A remote, unauthenticated
    attacker can exploit this to deference already freed
    memory, resulting in a denial of service condition or
    the execution of arbitrary code. (CVE-2015-4497)

  - A security feature bypass vulnerability exists due to a
    flaw that allows the manipulation of the 'data:' URL on
    a loaded web page without install permission prompts
    being displayed to the user. A remote, unauthenticated
    attacker can exploit this to install add-ons from a
    malicious source. (CVE-2015-4498)");
