{"id":"USN-2458-1","summary":"firefox vulnerabilities","details":"Christian Holler, Patrick McManus, Christoph Diehl, Gary Kwong, Jesse\nRuderman, Byron Campen, Terrence Cole, and Nils Ohlmeier discovered\nmultiple memory safety issues in Firefox. 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. (CVE-2014-8642)\n","modified":"2026-02-10T04:40:51Z","published":"2015-01-14T21:27:04Z","related":["UBUNTU-CVE-2014-8634","UBUNTU-CVE-2014-8635","UBUNTU-CVE-2014-8636","UBUNTU-CVE-2014-8637","UBUNTU-CVE-2014-8638","UBUNTU-CVE-2014-8639","UBUNTU-CVE-2014-8640","UBUNTU-CVE-2014-8641","UBUNTU-CVE-2014-8642"],"upstream":["CVE-2014-8634","CVE-2014-8635","CVE-2014-8636","CVE-2014-8637","CVE-2014-8638","CVE-2014-8639","CVE-2014-8640","CVE-2014-8641","CVE-2014-8642","UBUNTU-CVE-2014-8634","UBUNTU-CVE-2014-8635","UBUNTU-CVE-2014-8636","UBUNTU-CVE-2014-8637","UBUNTU-CVE-2014-8638","UBUNTU-CVE-2014-8639","UBUNTU-CVE-2014-8640","UBUNTU-CVE-2014-8641","UBUNTU-CVE-2014-8642"],"references":[{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-2458-1"},{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2014-8634"},{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2014-8635"},{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2014-8636"},{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2014-8637"},{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2014-8638"},{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2014-8639"},{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2014-8640"},{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2014-8641"},{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2014-8642"}],"affected":[{"package":{"name":"firefox","ecosystem":"Ubuntu:14.04:LTS","purl":"pkg:deb/ubuntu/firefox@35.0+build3-0ubuntu0.14.04.2?arch=source&distro=trusty"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"35.0+build3-0ubuntu0.14.04.2"}]}],"versions":["24.0+build1-0ubuntu1","25.0+build3-0ubuntu0.13.10.1","28.0~b2+build1-0ubuntu2","28.0+build1-0ubuntu1","28.0+build2-0ubuntu1","28.0+build2-0ubuntu2","29.0+build1-0ubuntu0.14.04.2","30.0+build1-0ubuntu0.14.04.3","31.0+build1-0ubuntu0.14.04.1","32.0+build1-0ubuntu0.14.04.1","32.0.3+build1-0ubuntu0.14.04.1","33.0+build2-0ubuntu0.14.04.1","34.0+build2-0ubuntu0.14.04.1"],"ecosystem_specific":{"binaries":[{"binary_version":"35.0+build3-0ubuntu0.14.04.2","binary_name":"firefox"},{"binary_version":"35.0+build3-0ubuntu0.14.04.2","binary_name":"firefox-dev"},{"binary_version":"35.0+build3-0ubuntu0.14.04.2","binary_name":"firefox-globalmenu"},{"binary_version":"35.0+build3-0ubuntu0.14.04.2","binary_name":"firefox-mozsymbols"},{"binary_version":"35.0+build3-0ubuntu0.14.04.2","binary_name":"firefox-testsuite"}],"availability":"No subscription required"},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/usn/USN-2458-1.json","cves_map":{"ecosystem":"Ubuntu:14.04:LTS","cves":[{"severity":[{"type":"Ubuntu","score":"medium"}],"id":"CVE-2014-8634"},{"severity":[{"type":"Ubuntu","score":"medium"}],"id":"CVE-2014-8635"},{"severity":[{"type":"Ubuntu","score":"medium"}],"id":"CVE-2014-8636"},{"severity":[{"type":"Ubuntu","score":"medium"}],"id":"CVE-2014-8637"},{"severity":[{"type":"Ubuntu","score":"medium"}],"id":"CVE-2014-8638"},{"severity":[{"type":"Ubuntu","score":"medium"}],"id":"CVE-2014-8639"},{"severity":[{"type":"Ubuntu","score":"medium"}],"id":"CVE-2014-8640"},{"severity":[{"type":"Ubuntu","score":"medium"}],"id":"CVE-2014-8641"},{"severity":[{"type":"Ubuntu","score":"low"}],"id":"CVE-2014-8642"}]}}}],"schema_version":"1.7.3"}
