{"id":"UBUNTU-CVE-2020-8619","details":"In ISC BIND9 versions BIND 9.11.14 -\u003e 9.11.19, BIND 9.14.9 -\u003e 9.14.12, BIND 9.16.0 -\u003e 9.16.3, BIND Supported Preview Edition 9.11.14-S1 -\u003e 9.11.19-S1: Unless a nameserver is providing authoritative service for one or more zones and at least one zone contains an empty non-terminal entry containing an asterisk (\"*\") character, this defect cannot be encountered. A would-be attacker who is allowed to change zone content could theoretically introduce such a record in order to exploit this condition to cause denial of service, though we consider the use of this vector unlikely because any such attack would require a significant privilege level and be easily traceable.","modified":"2026-02-04T04:36:59.039248Z","published":"2020-06-17T00:00:00Z","related":["USN-4399-1"],"upstream":["CVE-2020-8619"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2020-8619"},{"type":"REPORT","url":"https://kb.isc.org/docs/cve-2020-8619"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-4399-1"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2020-8619"}],"affected":[{"package":{"name":"bind9","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/bind9@1:9.16.1-0ubuntu2.2?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1:9.16.1-0ubuntu2.2"}]}],"versions":["1:9.11.5.P4+dfsg-5.1ubuntu2","1:9.11.5.P4+dfsg-5.1ubuntu3","1:9.11.5.P4+dfsg-5.1ubuntu4","1:9.11.5.P4+dfsg-5.1ubuntu5","1:9.11.14+dfsg-1ubuntu1","1:9.11.14+dfsg-3ubuntu1","1:9.16.0-1ubuntu3","1:9.16.0-1ubuntu4","1:9.16.0-1ubuntu5","1:9.16.1-0ubuntu1","1:9.16.1-0ubuntu2","1:9.16.1-0ubuntu2.1"],"ecosystem_specific":{"availability":"No subscription required","binaries":[{"binary_version":"1:9.16.1-0ubuntu2.2","binary_name":"bind9"},{"binary_version":"1:9.16.1-0ubuntu2.2","binary_name":"bind9-dnsutils"},{"binary_version":"1:9.16.1-0ubuntu2.2","binary_name":"bind9-host"},{"binary_version":"1:9.16.1-0ubuntu2.2","binary_name":"bind9-libs"},{"binary_version":"1:9.16.1-0ubuntu2.2","binary_name":"bind9-utils"},{"binary_version":"1:9.16.1-0ubuntu2.2","binary_name":"bind9utils"},{"binary_version":"1:9.16.1-0ubuntu2.2","binary_name":"dnsutils"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2020/UBUNTU-CVE-2020-8619.json"}}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:H"},{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:H"},{"type":"Ubuntu","score":"medium"}]}
