The decrease_ref_count function in libvpx in Mozilla Firefox before 40.0 and Firefox ESR 38.x before 38.2 allows remote attackers to execute arbitrary code or cause a denial of service (out-of-bounds read) via malformed WebM video data.

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.

MozillaFirefox ESR was updated to version 38.4.0ESR to fix multiple security issues.

The version of Mozilla Firefox is prior to 40.0 and is affected by multiple 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 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. 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 use-after-free error exists in the 'operator=()' function. An attacker can exploit this to dereference already freed memory, resulting in the execution of arbitrary code. (CVE-2015-4488) 
 - A memory corruption issue exists in the 'nsTArray_Impl()' function due to improper validation of user-supplied input during self-assignment. An attacker can exploit this to corrupt memory, resulting in the execution of arbitrary code. (CVE-2015-4489) 
 - 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) 
 - A use-after-free error exists in the 'XMLHttpRequest::Open()' function due to improper handling of recursive calls. An attacker can exploit this to dereference already freed memory, resulting in the execution of arbitrary code. (CVE-2015-4492) 
 - An integer underflow condition exists in the bundled libstagefright library. An attacker can exploit this to crash the application, resulting in a denial of service condition. (CVE-2015-4493) 
 - A flaw in the same origin policy in which an attacker can inject script code into a non-privileged part of browser's built-in PDF reader, resulting in gaining access to sensitive local files. (CVE-2015-4495)

The version of Firefox installed on the remote Windows 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)

  - 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)

The Mozilla Project reports :

Security researcher Abhishek Arya (Inferno) of the Google Chrome Security Team used the Address Sanitizer tool to discover two buffer overflow issues in the Libvpx library used for WebM video when decoding a malformed WebM video file. These buffer overflows result in potentially exploitable crashes.
