(CVE-2015-4473, CVE-2015-4474)\n \n Aki Helin discovered an out-of-bounds read when playing malformed MP3\n content in some circumstances. If a user were tricked in to opening a\n specially crafted website, an attacker could potentially exploit this to\n obtain sensitive information, cause a denial of service via application\n crash, or execute arbitrary code with the privileges of the user invoking\n Firefox. (CVE-2015-4475)\n \n A use-after-free was discovered during MediaStream playback in some\n circumstances. If a user were tricked in to opening a specially crafted\n website, an attacker could potentially exploit this to cause a denial of\n service via application crash or execute arbitrary code with the\n priviliges of the user invoking Firefox. (CVE-2015-4477)\n \n André Bargull discovered that non-configurable properties on javascript\n objects could be redefined when parsing JSON. If a user were tricked in to\n opening a specially crafted website, an attacker could potentially exploit\n this to bypass same-origin restrictions. (CVE-2015-4478)\n \n Multiple integer overflows were discovered in libstagefright. If a user\n were tricked in to opening a specially crafted website, an attacker could\n potentially exploit these to cause a denial of service via application\n crash, or execute arbitrary code with the privileges of the user invoking\n Firefox. (CVE-2015-4479, CVE-2015-4480, CVE-2015-4493)\n \n Jukka Jylänki discovered a crash that occurs because javascript does not\n properly gate access to Atomics or SharedArrayBuffers in some\n circumstances. If a user were tricked in to opening a specially crafted\n website, an attacker could potentially exploit this to cause a denial of\n service. (CVE-2015-4484)\n \n Abhishek Arya discovered 2 buffer overflows in libvpx when decoding\n malformed WebM content in some circumstances. If a user were tricked in\n to opening a specially crafted website, an attacker could potentially\n exploit these to cause a denial of service via application crash, or\n execute arbitrary code with the privileges of the user invoking Firefox.\n (CVE-2015-4485, CVE-2015-4486)\n \n Ronald Crane reported 3 security issues. If a user were tricked in to\n opening a specially crafted website, an attacker could potentially\n exploit these, in combination with another security vulnerability, to\n cause a denial of service via application crash, or execute arbitrary\n code with the privileges of the user invoking Firefox. (CVE-2015-4487,\n CVE-2015-4488, CVE-2015-4489)\n \n Christoph Kerschbaumer discovered an issue with Mozilla's implementation\n of Content Security Policy (CSP), which could allow for a more permissive\n usage in some cirucumstances. An attacker could potentially exploit this\n to conduct cross-site scripting (XSS) attacks. (CVE-2015-4490)\n \n Gustavo Grieco discovered a heap overflow in gdk-pixbuf. If a user were\n tricked in to opening a specially crafted website, an attacker could\n potentially exploit this to cause a denial of service via application\n crash or execute arbitrary code with the priviliges of the user invoking\n Firefox. (CVE-2015-4491)\n \n Looben Yang discovered a use-after-free when using XMLHttpRequest with\n shared workers in some circumstances. If a user were tricked in to opening\n a specially crafted website, an attacker could potentially exploit this to\n cause a denial of service via application crash or execute arbitrary code\n with the priviliges of the user invoking Firefox.
