{"schemaVersion":3,"id":"USN-2296-1","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"thunderbird vulnerabilities\n\nChristian Holler, David Keeler and Byron Campen discovered multiple memory\nsafety issues in Thunderbird. If a user were tricked in to opening a\nspecially crafted message with scripting enabled, 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\nThunderbird. (CVE-2014-1547)\n\nAtte Kettunen discovered a buffer overflow when interacting with WebAudio\nbuffers. If a user had enabled scripting, an attacker could potentially\nexploit this to cause a denial of service via application crash or execute\narbitrary code with the privileges of the user invoking Thunderbird.\n(CVE-2014-1549)\n\nAtte Kettunen discovered a use-after-free in WebAudio. If a user had\nenabled scripting, an attacker could potentially exploit this to cause a\ndenial of service via application crash or execute arbitrary code with the\nprivileges of the user invoking Thunderbird. (CVE-2014-1550)\n\nJethro Beekman discovered a use-after-free when the FireOnStateChange\nevent is triggered in some circumstances. If a user had enabled scripting,\nan attacker could potentially exploit this to cause a denial of service\nvia application crash or execute arbitrary code with the priviliges of\nthe user invoking Thunderbird. (CVE-2014-1555)\n\nPatrick Cozzi discovered a crash when using the Cesium JS library to\ngenerate WebGL content. If a user had enabled scripting, an attacker could\npotentially exploit this to execute arbitrary code with the privilges of\nthe user invoking Thunderbird. (CVE-2014-1556)\n\nTyson Smith and Jesse Schwartzentruber discovered a use-after-free in\nCERT_DestroyCertificate. If a user had enabled scripting, an attacker\ncould potentially exploit this to cause a denial of service via\napplication crash or execute arbitrary code with the privileges of the\nuser invoking Thunderbird. (CVE-2014-1544)\n\nA crash was discovered in Skia when scaling an image, if the scaling\noperation takes too long. If a user had enabled scripting, an attacker\ncould potentially exploit this to execute arbitrary code with the\nprivileges of the user invoking Thunderbird. (CVE-2014-1557)\n\nChristian Holler discovered several issues when parsing certificates\nwith non-standard character encoding, resulting in the inability to\nuse valid SSL certificates in some circumstances. (CVE-2014-1558,\nCVE-2014-1559, CVE-2014-1560)\n\nBoris Zbarsky discovered that network redirects could cause an iframe\nto escape the confinements defined by its sandbox attribute in some\ncircumstances. If a user had enabled scripting, an attacker could\npotentially exploit this to conduct cross-site scripting attacks.\n(CVE-2014-1552)","dates":{"published":"2014-07-22T21:08:37.000Z","modified":"2026-04-22T08:58:03.778Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":null,"severity":"unknown","version":null,"versionLabel":null,"source":null,"vector":null,"computed":false,"selection":"none"},"metrics":[]},"epss":{"probability":null,"percentile":null,"severity":"unknown","asOf":null,"change":{"pp":null,"baselineDate":null,"baselineScore":null},"history":[],"last30":[]},"kev":{"state":"not-listed","entries":[],"listedCount":0,"totalCatalogs":3,"catalogs":[{"source":"cisa","label":"CISA","listed":false,"entry":null},{"source":"enisa","label":"ENISA","listed":false,"entry":null},{"source":"circl","label":"CIRCL","listed":false,"entry":null}]},"ransomware":{"state":"none-recorded","sources":[]},"exploits":[],"exploitCount":0,"weaknesses":[],"affected":[{"vendor":"ubuntu","product":"thunderbird","name":"thunderbird","label":"thunderbird","ecosystem":"Ubuntu","cpePart":null,"purl":"pkg:deb/ubuntu/thunderbird","purlType":"deb","versions":[{"text":"< 1:31.0+build1-0ubuntu0.14.04.1","noFixRecorded":false,"fixedIn":null}],"versionsText":"< 1:31.0+build1-0ubuntu0.14.04.1","eol":null,"hubHref":null}],"affectedCount":1,"eol":{"hasEol":false,"count":0},"references":[{"url":"https://ubuntu.com/security/notices/USN-2296-1","label":"ubuntu.com/security/notices/USN-2296-1","hostname":"ubuntu.com","tags":["Advisory"]},{"url":"https://ubuntu.com/security/CVE-2014-1544","label":"ubuntu.com/security/CVE-2014-1544","hostname":"ubuntu.com","tags":["REPORT"]},{"url":"https://ubuntu.com/security/CVE-2014-1547","label":"ubuntu.com/security/CVE-2014-1547","hostname":"ubuntu.com","tags":["REPORT"]},{"url":"https://ubuntu.com/security/CVE-2014-1549","label":"ubuntu.com/security/CVE-2014-1549","hostname":"ubuntu.com","tags":["REPORT"]},{"url":"https://ubuntu.com/security/CVE-2014-1550","label":"ubuntu.com/security/CVE-2014-1550","hostname":"ubuntu.com","tags":["REPORT"]},{"url":"https://ubuntu.com/security/CVE-2014-1552","label":"ubuntu.com/security/CVE-2014-1552","hostname":"ubuntu.com","tags":["REPORT"]},{"url":"https://ubuntu.com/security/CVE-2014-1555","label":"ubuntu.com/security/CVE-2014-1555","hostname":"ubuntu.com","tags":["REPORT"]},{"url":"https://ubuntu.com/security/CVE-2014-1556","label":"ubuntu.com/security/CVE-2014-1556","hostname":"ubuntu.com","tags":["REPORT"]},{"url":"https://ubuntu.com/security/CVE-2014-1557","label":"ubuntu.com/security/CVE-2014-1557","hostname":"ubuntu.com","tags":["REPORT"]},{"url":"https://ubuntu.com/security/CVE-2014-1558","label":"ubuntu.com/security/CVE-2014-1558","hostname":"ubuntu.com","tags":["REPORT"]},{"url":"https://ubuntu.com/security/CVE-2014-1559","label":"ubuntu.com/security/CVE-2014-1559","hostname":"ubuntu.com","tags":["REPORT"]},{"url":"https://ubuntu.com/security/CVE-2014-1560","label":"ubuntu.com/security/CVE-2014-1560","hostname":"ubuntu.com","tags":["REPORT"]},{"url":"https://launchpad.net/bugs/1346007","label":"launchpad.net/bugs/1346007","hostname":"launchpad.net","tags":["REPORT"]}],"lineage":{"upstream":["CVE-2014-1544","CVE-2014-1547","CVE-2014-1549","CVE-2014-1550","CVE-2014-1552","CVE-2014-1555","CVE-2014-1556","CVE-2014-1557","CVE-2014-1558","CVE-2014-1559","CVE-2014-1560"],"downstream":[],"duplicates":[],"related":["CVE-2014-1544","CVE-2014-1547","CVE-2014-1549","CVE-2014-1550","CVE-2014-1552","CVE-2014-1555","CVE-2014-1556","CVE-2014-1557","CVE-2014-1558","CVE-2014-1559","CVE-2014-1560"]},"timeline":[{"kind":"published","date":"2014-07-22T21:08:37.000Z","label":"Published","detail":"Vulnerability first disclosed.","source":null},{"kind":"modified","date":"2026-04-22T08:58:03.778Z","label":"Last modified","detail":"Vulnerability information updated.","source":null}],"risk":{"score":0,"level":"minimal","profile":"Default","thresholds":{"critical":75,"high":50,"medium":25,"low":10}},"meta":{"dataAsOf":"2026-10-19T21:11:05.224Z","stale":false,"partial":false}}
