{"url":"http://public2.vulnerablecode.io/api/vulnerabilities/62877?format=json","vulnerability_id":"VCID-7xac-5zdj-9fgk","summary":"Mozilla developers and community members Boris Zbarsky, Carsten Book, Christian Holler, Byron Campen, Jan de Mooij, Jason Kratzer, Jesse Schwartzentruber, Marcia Knous, Randell Jesup, Tyson Smith, and Ting-Yu Chou reported memory safety bugs present in Firefox 56. Some of these bugs showed evidence of memory corruption and we presume that with enough effort that some of these could be exploited to run arbitrary code.","aliases":[{"alias":"CVE-2017-7827"}],"fixed_packages":[{"url":"http://public2.vulnerablecode.io/api/packages/371492?format=json","purl":"pkg:alpm/archlinux/firefox@57.0-1","is_vulnerable":false,"affected_by_vulnerabilities":[],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:alpm/archlinux/firefox@57.0-1"},{"url":"http://public2.vulnerablecode.io/api/packages/583476?format=json","purl":"pkg:deb/debian/firefox@57.0-1?distro=sid","is_vulnerable":false,"affected_by_vulnerabilities":[],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:deb/debian/firefox@57.0-1%3Fdistro=sid"},{"url":"http://public2.vulnerablecode.io/api/packages/582059?format=json","purl":"pkg:deb/debian/firefox@149.0-1?distro=sid","is_vulnerable":false,"affected_by_vulnerabilities":[],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:deb/debian/firefox@149.0-1%3Fdistro=sid"},{"url":"http://public2.vulnerablecode.io/api/packages/1059611?format=json","purl":"pkg:deb/debian/firefox@149.0.2-1?distro=sid","is_vulnerable":false,"affected_by_vulnerabilities":[],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:deb/debian/firefox@149.0.2-1%3Fdistro=sid"},{"url":"http://public2.vulnerablecode.io/api/packages/1076056?format=json","purl":"pkg:deb/debian/firefox@150.0-1?distro=sid","is_vulnerable":false,"affected_by_vulnerabilities":[],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:deb/debian/firefox@150.0-1%3Fdistro=sid"},{"url":"http://public2.vulnerablecode.io/api/packages/1088670?format=json","purl":"pkg:deb/debian/firefox@150.0.1-1?distro=sid","is_vulnerable":false,"affected_by_vulnerabilities":[],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:deb/debian/firefox@150.0.1-1%3Fdistro=sid"}],"affected_packages":[{"url":"http://public2.vulnerablecode.io/api/packages/371491?format=json","purl":"pkg:alpm/archlinux/firefox@56.0.2-1","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-2xza-hhmr-5ybw"},{"vulnerability":"VCID-4437-azu7-hyhb"},{"vulnerability":"VCID-6a4w-c6p8-affn"},{"vulnerability":"VCID-7xac-5zdj-9fgk"},{"vulnerability":"VCID-bk86-keag-kfg8"},{"vulnerability":"VCID-dhyh-m8p3-ebdq"},{"vulnerability":"VCID-e4pk-uyeh-xfgk"},{"vulnerability":"VCID-ebzs-h9p8-tbb4"},{"vulnerability":"VCID-gkrs-1aat-efhf"},{"vulnerability":"VCID-ka31-epgw-2kcq"},{"vulnerability":"VCID-kg3p-hut6-47f6"},{"vulnerability":"VCID-qc2y-5tzg-ruav"},{"vulnerability":"VCID-wwjw-cqjk-8qe2"},{"vulnerability":"VCID-xn3a-bun2-vkhy"},{"vulnerability":"VCID-y92g-afff-2ua7"}],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:alpm/archlinux/firefox@56.0.2-1"}],"references":[{"reference_url":"https://api.first.org/data/v1/epss?cve=CVE-2017-7827","reference_id":"","reference_type":"","scores":[{"value":"0.02127","scoring_system":"epss","scoring_elements":"0.84173","published_at":"2026-04-11T12:55:00Z"},{"value":"0.02127","scoring_system":"epss","scoring_elements":"0.84094","published_at":"2026-04-01T12:55:00Z"},{"value":"0.02127","scoring_system":"epss","scoring_elements":"0.84185","published_at":"2026-04-16T12:55:00Z"},{"value":"0.02127","scoring_system":"epss","scoring_elements":"0.84162","published_at":"2026-04-13T12:55:00Z"},{"value":"0.02127","scoring_system":"epss","scoring_elements":"0.84167","published_at":"2026-04-12T12:55:00Z"},{"value":"0.02127","scoring_system":"epss","scoring_elements":"0.84107","published_at":"2026-04-02T12:55:00Z"},{"value":"0.02127","scoring_system":"epss","scoring_elements":"0.84124","published_at":"2026-04-04T12:55:00Z"},{"value":"0.02127","scoring_system":"epss","scoring_elements":"0.84127","published_at":"2026-04-07T12:55:00Z"},{"value":"0.02127","scoring_system":"epss","scoring_elements":"0.84149","published_at":"2026-04-08T12:55:00Z"},{"value":"0.02127","scoring_system":"epss","scoring_elements":"0.84155","published_at":"2026-04-09T12:55:00Z"},{"value":"0.02566","scoring_system":"epss","scoring_elements":"0.85605","published_at":"2026-05-05T12:55:00Z"},{"value":"0.02566","scoring_system":"epss","scoring_elements":"0.85561","published_at":"2026-04-18T12:55:00Z"},{"value":"0.02566","scoring_system":"epss","scoring_elements":"0.85557","published_at":"2026-04-21T12:55:00Z"},{"value":"0.02566","scoring_system":"epss","scoring_elements":"0.85579","published_at":"2026-04-24T12:55:00Z"},{"value":"0.02566","scoring_system":"epss","scoring_elements":"0.85588","published_at":"2026-04-29T12:55:00Z"}],"url":"https://api.first.org/data/v1/epss?cve=CVE-2017-7827"},{"reference_url":"https://bugzilla.mozilla.org/buglist.cgi?bug_id=1399922%2C1403646%2C1403716%2C1365894%2C1402876%2C1406154%2C1384121%2C1384615%2C1407375%2C1339485%2C1361432%2C1394031%2C1383019%2C1407032%2C1387845%2C1386490","reference_id":"","reference_type":"","scores":[],"url":"https://bugzilla.mozilla.org/buglist.cgi?bug_id=1399922%2C1403646%2C1403716%2C1365894%2C1402876%2C1406154%2C1384121%2C1384615%2C1407375%2C1339485%2C1361432%2C1394031%2C1383019%2C1407032%2C1387845%2C1386490"}
