(CVE-2015-4510)\n \n Francisco Alonso discovered an out-of-bounds read during 2D canvas\n rendering 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. (CVE-2015-4512)\n \n Jeff Walden discovered that changes could be made to immutable properties\n in some circumstances. If a user were tricked in to opening a specially\n crafted website, an attacker could potentially exploit this to execute\n arbitrary script in a privileged scope. (CVE-2015-4516)\n \n Ronald Crane reported multiple vulnerabilities. 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-2015-4517, CVE-2015-4521, CVE-2015-4522, CVE-2015-7174,\n CVE-2015-7175, CVE-2015-7176, CVE-2015-7177, CVE-2015-7180)\n \n Mario Gomes discovered that dragging and dropping an image after a\n redirect exposes the redirected URL to scripts.
