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)

Versions of Firefox OS prior to 2.2 are outdated and thus unpatched for the following vulnerabilities : 

 - A logic error in 'apps/system/js/usb_storage.js' that is triggered during the handling of USB mass storage. This may allow a local attacker with access to the USB host to gain access to USB media volumes that are locked with a passcode after a reboot or certain unspecified screen saver state changes. (CVE-2015-5960) 
 - A flaw exists in the SharedBufferManagerParent::RecvAllocateGrallocBuffer() function in 'gfx/layers/ipc/SharedBufferManagerParent.cpp'. This may allow an attacker to corrupt memory and cause a denial of service or potentially execute arbitrary code. (CVE-2015-5960) 
 - A flaw exists in the 'FxAccounts signup dialog' that is triggered as input passed via the COPPA error screen is not properly sanitized before being passed to the B2G root process. This may allow a remote attacker to inject arbitrary web content into the B2G root process. (CVE-2015-5961) 
 - A flaw exists in 'dom/messages/SystemMessagePermissionsChecker.jsm' within the WiFi-related system message, as the system fails to restrict system messages to applications with the 'wifi-manage' permissions. With an unprivileged application, a local attacker can gain access to limited information from system messages. (CVE-2015-4494) 
 - A use-after-free error affects the StyleAnimationValue::operator=() function in 'layout/style/StyleAnimationValue.cpp'. This may allow a context-dependent attacker to dereference already freed memory and potentially execute arbitrary code. (CVE-2015-4488) 
 - An unspecified flaw exists in the nsTArray_Impl() function. The issue is triggered as user-supplied input is not properly validated during self-assignment. This may allow a context-dependent attacker to corrupt memory and potentially execute arbitrary code. (CVE-2015-4489) 
 - An overflow condition affects the nsTSubstring::ReplacePrep() function. This may allow a context-dependent attacker to cause a buffer overflow, potentially allowing the execution of arbitrary code. (CVE-2015-4487) 
 - Gaia contains a flaw in the search app within 'apps/search/js/providers/provider.js' that is triggered during the handling of a specially crafted search link. When the link is opened in the browser and the browser is re-opened or a new tab is opened, a context-dependent attacker can potentially inject HTML content. (CVE-2015-2744) 
 - Gaia contains a flaw in 'apps/system/js/card.js' that is triggered when handling titles. When the link is opened in the browser and the HOME button is pressed or the Show Windows function is used, a context-dependent attacker can potentially inject HTML content. (CVE-2015-2745) 
 - A flaw affects the nsDocShell::LoadURI() function in 'docshell/base/nsDocShell.cpp' that is triggered when converting an expanded principal into inheriting the current principal. This may allow a context-dependent attacker to bypass the same-origin policy and disclose the contents of local files. (CVE-2015-4495)
