If a user were tricked in to\nopening a specially crafted website, an attacker could potentially exploit\nthese to cause a denial of service via application crash, or execute\narbitrary code with the privileges of the user invoking Firefox.\n(CVE-2014-8634, CVE-2014-8635)\n\nBobby Holley discovered that some DOM objects with certain properties\ncan bypass XrayWrappers in some circumstances. If a user were tricked in\nto opening a specially crafted website, an attacker could potentially\nexploit this to bypass security restrictions. (CVE-2014-8636)\n\nMichal Zalewski discovered a use of uninitialized memory when rendering\nmalformed bitmap images on a canvas element. If a user were tricked in to\nopening a specially crafted website, an attacker could potentially\nexploit this to steal confidential information. (CVE-2014-8637)\n\nMuneaki Nishimura discovered that requests from navigator.sendBeacon()\nlack an origin header. If a user were tricked in to opening a specially\ncrafted website, an attacker could potentially exploit this to conduct\ncross-site request forgery (XSRF) attacks. (CVE-2014-8638)\n\nXiaofeng Zheng discovered that a web proxy returning a 407 response\ncould inject cookies in to the originally requested domain. If a user\nconnected to a malicious web proxy, an attacker could potentially exploit\nthis to conduct session-fixation attacks. (CVE-2014-8639)\n\nHolger Fuhrmannek discovered a crash in Web Audio while manipulating\ntimelines. If a user were tricked in to opening a specially crafted\nwebsite, an attacker could potentially exploit this to cause a denial\nof service. (CVE-2014-8640)\n\nMitchell Harper discovered a use-after-free in WebRTC. If a user were\ntricked in to opening a specially crafted website, an attacker could\npotentially exploit this to cause a denial of service via application\ncrash, or execute arbitrary code with the privileges of the user invoking\nFirefox. (CVE-2014-8641)\n\nBrian Smith discovered that OCSP responses would fail to verify if signed\nby a delegated OCSP responder certificate with the id-pkix-ocsp-nocheck\nextension, potentially allowing a user to connect to a site with a revoked\ncertificate.
