"summary": "firefox vulnerabilities",
"details": "Karthikeyan Bhargavan discovered that NSS incorrectly handled state\ntransitions for the TLS state machine. If a remote attacker were able to\nperform a machine-in-the-middle attack, this flaw could be exploited to skip\nthe ServerKeyExchange message and remove the forward-secrecy property.\n(CVE-2015-2721)\n\nLooben Yan discovered 2 use-after-free issues when using XMLHttpRequest in\nsome circumstances. If a user were tricked in to opening a specially\ncrafted website, an attacker could potentially exploit these to cause a\ndenial of service via application crash, or execute arbitrary code with\nthe privileges of the user invoking Firefox. (CVE-2015-2722,\nCVE-2015-2733)\n\nBob Clary, Christian Holler, Bobby Holley, Andrew McCreight, Terrence\nCole, Steve Fink, Mats Palmgren, Wes Kocher, Andreas Pehrson, Tooru\nFujisawa, Andrew Sutherland, and Gary Kwong discovered multiple memory\nsafety issues in Firefox. If a user were tricked in to opening a specially\ncrafted website, an attacker could potentially exploit these to cause a\ndenial of service via application crash, or execute arbitrary code with\nthe privileges of the user invoking Firefox. (CVE-2015-2724,\nCVE-2015-2725, CVE-2015-2726)\n\nArmin Razmdjou discovered that opening hyperlinks with specific mouse\nand key combinations could allow a Chrome privileged URL to be opened\nwithout context restrictions being preserved. If a user were tricked in to\nopening a specially crafted website, an attacker could potentially exploit\nthis to bypass security restrictions. (CVE-2015-2727)\n\nPaul Bandha discovered a type confusion bug in the Indexed DB Manager. If\na user were tricked in to opening a specially crafted website, an attacker\ncould potentially exploit this to cause a denial of service via\napplication crash or execute arbitrary code with the priviliges of the\nuser invoking Firefox. (CVE-2015-2728)\n\nHolger Fuhrmannek discovered an out-of-bounds read in Web Audio. If a\nuser were tricked in to opening a specially crafted website, an attacker\ncould potentially exploit this to obtain sensitive information.\n(CVE-2015-2729)\n\nWatson Ladd discovered that NSS incorrectly handled Elliptical Curve\nCryptography (ECC) multiplication. A remote attacker could possibly use\nthis issue to spoof ECDSA signatures. (CVE-2015-2730)\n\nA use-after-free was discovered when a Content Policy modifies the DOM to\nremove a DOM object. If a user were tricked in to opening a specially\ncrafted website, an attacker could potentially exploit this to cause a\ndenial of service via application crash or execute arbitrary code with the\npriviliges of the user invoking Firefox. (CVE-2015-2731)\n\nRonald Crane discovered multiple security vulnerabilities. If a user were\ntricked in to opening a specially crafted website, an attacker could\npotentially exploit these to cause a denial of service via application\ncrash, or execute arbitrary code with the privileges of the user invoking\nFirefox. (CVE-2015-2734, CVE-2015-2735, CVE-2015-2736, CVE-2015-2737,\nCVE-2015-2738, CVE-2015-2739, CVE-2015-2740)\n\nDavid Keeler discovered that key pinning checks can be skipped when an\noverridable certificate error occurs. This allows a user to manually\noverride an error for a fake certificate, but cannot be exploited on its\nown. (CVE-2015-2741)\n\nJonas Jenwald discovered that some internal workers were incorrectly\nexecuted with a high privilege. If a user were tricked in to opening a\nspecially crafted website, an attacker could potentially exploit this in\ncombination with another security vulnerability, to execute arbitrary code\nin a privileged scope. (CVE-2015-2743)\n\nMatthew Green discovered a DHE key processing issue in NSS where a MITM\ncould force a server to downgrade TLS connections to 512-bit export-grade\ncryptography. An attacker could potentially exploit this to impersonate\nthe server. (CVE-2015-4000)\n",
