{"id":"ALPINE-CVE-2023-3341","details":"The code that processes control channel messages sent to `named` calls certain functions recursively during packet parsing. Recursion depth is only limited by the maximum accepted packet size; depending on the environment, this may cause the packet-parsing code to run out of available stack memory, causing `named` to terminate unexpectedly. Since each incoming control channel message is fully parsed before its contents are authenticated, exploiting this flaw does not require the attacker to hold a valid RNDC key; only network access to the control channel's configured TCP port is necessary.\nThis issue affects BIND 9 versions 9.2.0 through 9.16.43, 9.18.0 through 9.18.18, 9.19.0 through 9.19.16, 9.9.3-S1 through 9.16.43-S1, and 9.18.0-S1 through 9.18.18-S1.","modified":"2026-08-07T06:18:01.496039642Z","published":"2023-09-20T13:15:11.770Z","upstream":["CVE-2023-3341"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2023-3341"}],"affected":[{"package":{"name":"bind","ecosystem":"Alpine:v3.15","purl":"pkg:apk/alpine/bind?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"9.2.0"},{"fixed":"9.16.44-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-3341.json"}},{"package":{"name":"bind","ecosystem":"Alpine:v3.16","purl":"pkg:apk/alpine/bind?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"9.2.0"},{"fixed":"9.16.44-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-3341.json"}},{"package":{"name":"bind","ecosystem":"Alpine:v3.17","purl":"pkg:apk/alpine/bind?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"9.2.0"},{"fixed":"9.18.19-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-3341.json"}},{"package":{"name":"bind","ecosystem":"Alpine:v3.18","purl":"pkg:apk/alpine/bind?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"9.2.0"},{"fixed":"9.18.19-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-3341.json"}},{"package":{"name":"bind","ecosystem":"Alpine:v3.19","purl":"pkg:apk/alpine/bind?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"9.2.0"},{"fixed":"9.18.19-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-3341.json"}},{"package":{"name":"bind","ecosystem":"Alpine:v3.20","purl":"pkg:apk/alpine/bind?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"9.2.0"},{"fixed":"9.18.19-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-3341.json"}},{"package":{"name":"bind","ecosystem":"Alpine:v3.21","purl":"pkg:apk/alpine/bind?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"9.2.0"},{"fixed":"9.18.19-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-3341.json"}},{"package":{"name":"bind","ecosystem":"Alpine:v3.22","purl":"pkg:apk/alpine/bind?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"9.2.0"},{"fixed":"9.18.19-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-3341.json"}},{"package":{"name":"bind","ecosystem":"Alpine:v3.23","purl":"pkg:apk/alpine/bind?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"9.2.0"},{"fixed":"9.18.19-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-3341.json"}},{"package":{"name":"bind","ecosystem":"Alpine:v3.24","purl":"pkg:apk/alpine/bind?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"9.2.0"},{"fixed":"9.18.19-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-3341.json"}}],"schema_version":"1.8.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
