An attacker can     exploit this to cause a buffer overflow, resulting in a     denial of service condition or the execution of     arbitrary code. (CVE-2016-0718)

  - An information disclosure vulnerability exists due to a     failure to close connections after requesting favicons.
    An attacker can exploit this to continue to send     requests to the user's browser and disclose sensitive     information.(CVE-2016-2830)

  - Multiple memory corruption issues exist due to improper     validation of user-supplied input. An attacker can     exploit these issues to cause a denial of service     condition or the execution of arbitrary code.
    (CVE-2016-2835, CVE-2016-2836)

  - An overflow condition exists in the ClearKey Content     Decryption Module (CDM) used by the Encrypted Media     Extensions (EME) API due to improper validation of     user-supplied input. An attacker can exploit this to     cause a buffer overflow, resulting in a denial of     service condition or the execution of arbitrary code.
    (CVE-2016-2837)

  - An overflow condition exists in the ProcessPDI()     function in layout/base/nsBidi.cpp due to improper     validation of user-supplied input. An attacker can     exploit this to cause a heap-based buffer overflow,     resulting in a denial of service condition or the     execution of arbitrary code. (CVE-2016-2838)

  - A flaw exists in the Resource Timing API during page     navigation. An attacker can exploit this to disclose     sensitive information. (CVE-2016-5250)

  - A flaw exists that is triggered when decoding     url-encoded values in 'data:' URLs. An attacker can     exploit this, via non-ASCII or emoji characters, to     spoof the address in the address bar. (CVE-2016-5251)

  - An underflow condition exists in the BasePoint4d()     function in gfx/2d/Matrix.h due to improper validation     of user-supplied input when calculating clipping regions     in 2D graphics. A remote attacker can exploit this to     cause a stack-based buffer underflow, resulting in a     denial of service condition or the execution of     arbitrary code. (CVE-2016-5252)

  - A flaw in the updater service exists when launched using     the callback application path parameter that allows an     attacker to escalate privileges. (CVE-2016-5253)

  - A use-after-free error exists in the KeyDown() function     in layout/xul/nsXULPopupManager.cpp when using the alt     key in conjunction with top level menu items. An     attacker can exploit this to dereference already freed     memory, resulting in a denial of service condition or     the execution of arbitrary code. (CVE-2016-5254)

  - A use-after-free error exists in the sweep() function     that is triggered when handling objects and pointers     during incremental garbage collection. An attacker can     exploit this to dereference already freed memory,     resulting in a denial of service condition or the     execution of arbitrary code. (CVE-2016-5255)

  - A use-after-free error exists in WebRTC that is     triggered when handling DTLS objects. An attacker can     exploit this to dereference already freed memory,     resulting in a denial of service condition or the     execution of arbitrary code. (CVE-2016-5258)

  - A use-after-free error exists in the DestroySyncLoop()     function in dom/workers/WorkerPrivate.cpp that is     triggered when handling nested sync event loops in     Service Workers. An attacker can exploit this to     dereference already freed memory, resulting in a denial     of service condition or the execution of arbitrary code.
    (CVE-2016-5259)

    (CVE-2016-5264)

  - A flaw exists in the Redirect() function in     nsBaseChannel.cpp that is triggered when a malicious     shortcut is called from the same directory as a local     HTML file. An attacker can exploit this to bypass the     same-origin policy. (CVE-2016-5265)

  - A flaw exists due to a failure to properly filter file     URIs dragged from a web page to a different piece of     software. An attacker can exploit this to disclose     sensitive information. (CVE-2016-5266)

  - A flaw exists that is triggered when handling certain     specific 'about:' URLs that allows an attacker to spoof     the contents of system information or error messages     (CVE-2016-5268)

  - A flaw exists in woff2 that is triggered during the     handling of TTC detection. An attacker can exploit this     to have an unspecified impact.

  - Multiple unspecified flaws exist in woff2 that allow an     attacker to cause a denial of service condition.
