{"id":"DEBIAN-CVE-2020-8625","details":"BIND servers are vulnerable if they are running an affected version and are configured to use GSS-TSIG features. In a configuration which uses BIND's default settings the vulnerable code path is not exposed, but a server can be rendered vulnerable by explicitly setting valid values for the tkey-gssapi-keytab or tkey-gssapi-credentialconfiguration options. Although the default configuration is not vulnerable, GSS-TSIG is frequently used in networks where BIND is integrated with Samba, as well as in mixed-server environments that combine BIND servers with Active Directory domain controllers. The most likely outcome of a successful exploitation of the vulnerability is a crash of the named process. However, remote code execution, while unproven, is theoretically possible. Affects: BIND 9.5.0 -\u003e 9.11.27, 9.12.0 -\u003e 9.16.11, and versions BIND 9.11.3-S1 -\u003e 9.11.27-S1 and 9.16.8-S1 -\u003e 9.16.11-S1 of BIND Supported Preview Edition. Also release versions 9.17.0 -\u003e 9.17.1 of the BIND 9.17 development branch","modified":"2026-09-01T16:04:34.112583348Z","published":"2021-02-17T23:15:13.530Z","upstream":["CVE-2020-8625"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2020-8625"}],"affected":[{"package":{"name":"bind9","ecosystem":"Debian:12","purl":"pkg:deb/debian/bind9?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1:9.16.12-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2020-8625.json"}},{"package":{"name":"bind9","ecosystem":"Debian:13","purl":"pkg:deb/debian/bind9?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1:9.16.12-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2020-8625.json"}},{"package":{"name":"bind9","ecosystem":"Debian:14","purl":"pkg:deb/debian/bind9?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1:9.16.12-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2020-8625.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
