{"id":"MGASA-2020-0348","summary":"Updated firefox packages fix security vulnerabilities","details":"By holding a reference to the eval() function from an about:blank window, a\nmalicious webpage could have gained access to the InstallTrigger object which\nwould allow them to prompt the user to install an extension. Combined with user\nconfusion, this could result in an unintended or malicious extension being\ninstalled (CVE-2020-15664).\n\nWhen aborting an operation, such as a fetch, an abort signal may be deleted\nwhile alerting the objects to be notified. This results in a use-after-free and\nwe presume that with enough effort it could have been exploited to run\narbitrary code (CVE-2020-15669).\n","modified":"2026-01-30T10:23:39.163133Z","published":"2020-08-27T15:52:56Z","related":["CVE-2020-15664","CVE-2020-15669"],"references":[{"type":"ADVISORY","url":"https://advisories.mageia.org/MGASA-2020-0348.html"},{"type":"REPORT","url":"https://bugs.mageia.org/show_bug.cgi?id=27193"},{"type":"REPORT","url":"https://groups.google.com/g/mozilla.dev.tech.nspr/c/YLamaq1rVco"},{"type":"REPORT","url":"https://www.mozilla.org/en-US/security/advisories/mfsa2020-37/"}],"affected":[{"package":{"name":"nspr","ecosystem":"Mageia:7","purl":"pkg:rpm/mageia/nspr?arch=source&distro=mageia-7"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.28-1.mga7"}]}],"ecosystem_specific":{"section":"core"},"database_specific":{"source":"https://advisories.mageia.org/MGASA-2020-0348.json"}},{"package":{"name":"firefox","ecosystem":"Mageia:7","purl":"pkg:rpm/mageia/firefox?arch=source&distro=mageia-7"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"68.12.0-2.mga7"}]}],"ecosystem_specific":{"section":"core"},"database_specific":{"source":"https://advisories.mageia.org/MGASA-2020-0348.json"}},{"package":{"name":"firefox-l10n","ecosystem":"Mageia:7","purl":"pkg:rpm/mageia/firefox-l10n?arch=source&distro=mageia-7"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"68.12.0-1.mga7"}]}],"ecosystem_specific":{"section":"core"},"database_specific":{"source":"https://advisories.mageia.org/MGASA-2020-0348.json"}}],"schema_version":"1.7.3","credits":[{"name":"Mageia","contact":["https://wiki.mageia.org/en/Packages_Security_Team"],"type":"COORDINATOR"}]}
