The remote host is affected by the vulnerability described in GLSA-201605-06 (Mozilla Products: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in Firefox, NSS, NSPR, and       Thunderbird. Please review the CVE identifiers referenced below for       details.
  Impact :

    A remote attacker could entice a user to view a specially crafted web       page or email, possibly resulting in execution of arbitrary code or a       Denial of Service condition. Furthermore, a remote attacker may be able       to perform Man-in-the-Middle attacks, obtain sensitive information, spoof       the address bar, conduct clickjacking attacks, bypass security       restrictions and protection mechanisms, or have other unspecified       impacts.
  Workaround :

    There is no known workaround at this time.

The version of Firefox installed on the remote Mac OS X host is prior to 40. It is, therefore, affected by the following vulnerabilities :

  - Multiple memory corruption issues exist that allow a     remote attacker, via a specially crafted web page, to     corrupt memory and potentially execute arbitrary code.
    (CVE-2015-4473)

  - Multiple memory corruption issues exist that allow a     remote attacker, via a specially crafted web page, to     corrupt memory and potentially execute arbitrary code.
    (CVE-2015-4474)

  - An out-of-bounds read error exists in the     PlayFromAudioQueue() function due to improper handling     of mismatched sample formats. A remote attacker can     exploit this, via a specially crafted MP3 file, to     disclose memory contents or execute arbitrary code.
    (CVE-2015-4475)

  - A use-after-free error exists in the Web Audio API     during MediaStream playback. A remote attacker can     exploit this to dereference already freed memory,     resulting in the potential execution of arbitrary code.
    (CVE-2015-4477)

  - A same-origin policy bypass vulnerability exists due to     non-configurable properties being redefined in violation     of the ECMAScript 6 standard during JSON parsing. A     remote attacker can exploit this, by editing these     properties to arbitrary values, to bypass the     same-origin policy. (CVE-2015-4478)

  - Multiple integer overflow conditions exist due to     improper validation of user-supplied input when handling     'saio' chunks in MPEG4 video. A remote attacker can     exploit this, via a specially crafted MPEG4 file, to     execute arbitrary code. (CVE-2015-4479)

  - An integer overflow condition exists in the bundled     libstagefright component when handling H.264 media     content. A remote attacker can exploit this, via a     specially crafted MPEG4 file, to execute arbitrary code.
    (CVE-2015-4480)

  - An out-of-bounds write error exists due to an array     indexing flaw in the mar_consume_index() function when     handling index names in MAR files. An attacker can     exploit this to execute arbitrary code. (CVE-2015-4482)

  - A security bypass vulnerability exists due to a flaw in     the ShouldLoad() function that occurs during the     handling of POST requests to URLs using the 'feed:' URI     handler. An attacker can exploit this to bypass the     mixed content blocker. (CVE-2015-4483)

  - A denial of service vulnerability exists when handling     JavaScript using shared memory without properly gating     access to Atomics and SharedArrayBuffer views. An     attacker can exploit this to crash the program,     resulting in a denial of service condition.
    (CVE-2015-4484)

  - A heap-based buffer overflow condition exists in the     resize_context_buffers() function due to improper     validation of user-supplied input. A remote attacker can     exploit this, via specially crafted WebM content, to     cause a heap-based buffer overflow, resulting in the     execution of arbitrary code. (CVE-2015-4485)

  - A heap-based buffer overflow condition exists in the     decrease_ref_count() function due to improper validation     of user-supplied input. A remote attacker can exploit     this, via specially crafted WebM content, to cause a     heap-based buffer overflow, resulting in the execution     of arbitrary code. (CVE-2015-4486)

  - A buffer overflow condition exists in the ReplacePrep()     function. A remote attacker can exploit this to cause a     buffer overflow, resulting in the execution of arbitrary     code. (CVE-2015-4487)

  - A security bypass vulnerability exists due to a     discrepancy in the implementation of Content Security     Policy and the CSP specification. The specification     states that 'blob:', 'data:', and 'filesystem:' URLs     should be excluded in case of a wildcard when matching     source expressions, but Mozilla's implementation allows     these in the case of an asterisk wildcard. A remote     attacker can exploit this to bypass restrictions.
    (CVE-2015-4490)
