{"id":"CVE-2018-5736","details":"An error in zone database reference counting can lead to an assertion failure if a server which is running an affected version of BIND attempts several transfers of a slave zone in quick succession. This defect could be deliberately exercised by an attacker who is permitted to cause a vulnerable server to initiate zone transfers (for example: by sending valid NOTIFY messages), causing the named process to exit after failing the assertion test. Affects BIND 9.12.0 and 9.12.1.","modified":"2026-08-07T14:49:06.628779Z","published":"2019-01-16T20:29:00.830Z","related":["CGA-pxfg-jcfx-2cp2"],"references":[{"type":"ADVISORY","url":"http://www.securityfocus.com/bid/104386"},{"type":"ADVISORY","url":"http://www.securitytracker.com/id/1040941"},{"type":"ADVISORY","url":"https://kb.isc.org/docs/aa-01602"},{"type":"ADVISORY","url":"https://security.netapp.com/advisory/ntap-20180926-0004/"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/isc-projects/bind9","events":[{"introduced":"71a40862c0be867999867cd99e21c2266a5e452b"},{"last_affected":"b2307b25465c16d37ff6de22438a2d214287417c"}],"database_specific":{"cpe":["cpe:2.3:a:isc:bind:9.12.0:*:*:*:*:*:*:*","cpe:2.3:a:isc:bind:9.12.1:*:*:*:*:*:*:*"],"extracted_events":[{"introduced":"9.12.0"},{"last_affected":"9.12.0"},{"introduced":"9.12.1"},{"last_affected":"9.12.1"}],"source":"CPE_STRING"}}],"versions":["9.12.0","9.12.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2018-5736.json"}},{"ranges":[{"type":"GIT","repo":"https://gitlab.isc.org/isc-projects/bind9","events":[{"introduced":"71a40862c0be867999867cd99e21c2266a5e452b"},{"last_affected":"b2307b25465c16d37ff6de22438a2d214287417c"}],"database_specific":{"cpe":["cpe:2.3:a:isc:bind:9.12.0:*:*:*:*:*:*:*","cpe:2.3:a:isc:bind:9.12.1:*:*:*:*:*:*:*"],"extracted_events":[{"introduced":"9.12.0"},{"last_affected":"9.12.0"},{"introduced":"9.12.1"},{"last_affected":"9.12.1"}],"source":"CPE_STRING"}}],"versions":["9.12.0","9.12.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2018-5736.json"}}],"schema_version":"1.8.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
