{"id":"CVE-2018-5737","details":"A problem with the implementation of the new serve-stale feature in BIND 9.12 can lead to an assertion failure in rbtdb.c, even when stale-answer-enable is off. Additionally, problematic interaction between the serve-stale feature and NSEC aggressive negative caching can in some cases cause undesirable behavior from named, such as a recursion loop or excessive logging. Deliberate exploitation of this condition could cause operational problems depending on the particular manifestation -- either degradation or denial of service. Affects BIND 9.12.0 and 9.12.1.","modified":"2026-05-08T15:04:49.580148Z","published":"2019-01-16T20:29:00.877Z","related":["CGA-74fq-hxrv-4p44","openSUSE-SU-2024:10650-1"],"references":[{"type":"ADVISORY","url":"http://www.securityfocus.com/bid/104236"},{"type":"ADVISORY","url":"http://www.securitytracker.com/id/1040942"},{"type":"ADVISORY","url":"https://kb.isc.org/docs/aa-01606"},{"type":"ADVISORY","url":"https://security.netapp.com/advisory/ntap-20180926-0004/"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://gitlab.isc.org/isc-projects/bind9","events":[{"introduced":"0"},{"last_affected":"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:*:*:*:*:*:*:*"],"source":"CPE_FIELD","extracted_events":[{"introduced":"0"},{"last_affected":"9.12.0"},{"last_affected":"9.12.1"}]}}],"versions":["v9.10.0a1","v9.10.0a2","v9.10.0b1","v9.10.0b2","v9.10.0rc1","v9.11.0a1","v9.11.0a2","v9.11.0a3","v9.12.0","v9.12.0a1","v9.12.0b1","v9.12.0b2","v9.12.0rc1","v9.12.0rc2","v9.12.0rc3","v9.12.1","v9.12.1b1","v9.12.1rc1","v9.5.0a1","v9.5.0a2","v9.5.0a3","v9.5.0a4","v9.5.0a5","v9.5.0a6","v9.7.0a1"],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2018-5737.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
