    Mozilla Firefox is an open source web browser. XULRunner provides the XUL     Runtime environment for Mozilla Firefox.

    Several flaws were found in the processing of malformed web content. A web     page containing malicious content could cause Firefox to crash or,     potentially, execute arbitrary code with the privileges of the user running     Firefox. (CVE-2015-4473, CVE-2015-4475, CVE-2015-4478, CVE-2015-4479,     CVE-2015-4480, CVE-2015-4493, CVE-2015-4484, CVE-2015-4491, CVE-2015-4485,     CVE-2015-4486, CVE-2015-4487, CVE-2015-4488, CVE-2015-4489, CVE-2015-4492)

    Red Hat would like to thank the Mozilla project for reporting these issues.

    (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 arbitrary file overwrite vulnerability exists in the     Mozilla Maintenance Service due to a race condition. An     attacker can exploit this, via the use of a hard link,     to overwrite arbitrary files with log output.
    (CVE-2015-4481)

  - 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.
