{"id":"ALSA-2024:1781","summary":"Important: bind9.16 security update","details":"The Berkeley Internet Name Domain (BIND) is an implementation of the Domain Name System (DNS) protocols. BIND includes a DNS server (named); a resolver library (routines for applications to use when interfacing with DNS); and tools for verifying that the DNS server is operating correctly.\n\nSecurity Fix(es):\n\n* bind9: Parsing large DNS messages may cause excessive CPU load (CVE-2023-4408)\n* bind9: Querying RFC 1918 reverse zones may cause an assertion failure when “nxdomain-redirect” is enabled (CVE-2023-5517)\n* bind9: Enabling both DNS64 and serve-stale may cause an assertion failure during recursive resolution (CVE-2023-5679)\n* bind9: Specific recursive query patterns may lead to an out-of-memory condition (CVE-2023-6516)\n* bind9: KeyTrap - Extreme CPU consumption in DNSSEC validator (CVE-2023-50387)\n* bind9: Preparing an NSEC3 closest encloser proof can exhaust CPU resources (CVE-2023-50868)\n\nFor more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.","modified":"2026-01-30T01:08:21.754157Z","published":"2024-04-11T00:00:00Z","related":["CVE-2023-4408","CVE-2023-50387","CVE-2023-50868","CVE-2023-5517","CVE-2023-5679","CVE-2023-6516"],"references":[{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2024:1781"},{"type":"REPORT","url":"https://access.redhat.com/security/cve/CVE-2023-4408"},{"type":"REPORT","url":"https://access.redhat.com/security/cve/CVE-2023-50387"},{"type":"REPORT","url":"https://access.redhat.com/security/cve/CVE-2023-50868"},{"type":"REPORT","url":"https://access.redhat.com/security/cve/CVE-2023-5517"},{"type":"REPORT","url":"https://access.redhat.com/security/cve/CVE-2023-5679"},{"type":"REPORT","url":"https://access.redhat.com/security/cve/CVE-2023-6516"},{"type":"REPORT","url":"https://bugzilla.redhat.com/2263896"},{"type":"REPORT","url":"https://bugzilla.redhat.com/2263897"},{"type":"REPORT","url":"https://bugzilla.redhat.com/2263909"},{"type":"REPORT","url":"https://bugzilla.redhat.com/2263911"},{"type":"REPORT","url":"https://bugzilla.redhat.com/2263914"},{"type":"REPORT","url":"https://bugzilla.redhat.com/2263917"},{"type":"ADVISORY","url":"https://errata.almalinux.org/8/ALSA-2024-1781.html"}],"affected":[{"package":{"name":"bind9.16","ecosystem":"AlmaLinux:8","purl":"pkg:rpm/almalinux/bind9.16"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"32:9.16.23-0.16.el8_9.2.alma.1"}]}],"database_specific":{"source":"https://github.com/AlmaLinux/osv-database/blob/master/advisories/almalinux8/ALSA-2024:1781.json"}},{"package":{"name":"bind9.16-chroot","ecosystem":"AlmaLinux:8","purl":"pkg:rpm/almalinux/bind9.16-chroot"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"32:9.16.23-0.16.el8_9.2.alma.1"}]}],"database_specific":{"source":"https://github.com/AlmaLinux/osv-database/blob/master/advisories/almalinux8/ALSA-2024:1781.json"}},{"package":{"name":"bind9.16-devel","ecosystem":"AlmaLinux:8","purl":"pkg:rpm/almalinux/bind9.16-devel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"32:9.16.23-0.16.el8_9.2.alma.1"}]}],"database_specific":{"source":"https://github.com/AlmaLinux/osv-database/blob/master/advisories/almalinux8/ALSA-2024:1781.json"}},{"package":{"name":"bind9.16-dnssec-utils","ecosystem":"AlmaLinux:8","purl":"pkg:rpm/almalinux/bind9.16-dnssec-utils"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"32:9.16.23-0.16.el8_9.2.alma.1"}]}],"database_specific":{"source":"https://github.com/AlmaLinux/osv-database/blob/master/advisories/almalinux8/ALSA-2024:1781.json"}},{"package":{"name":"bind9.16-doc","ecosystem":"AlmaLinux:8","purl":"pkg:rpm/almalinux/bind9.16-doc"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"32:9.16.23-0.16.el8_9.2.alma.1"}]}],"database_specific":{"source":"https://github.com/AlmaLinux/osv-database/blob/master/advisories/almalinux8/ALSA-2024:1781.json"}},{"package":{"name":"bind9.16-libs","ecosystem":"AlmaLinux:8","purl":"pkg:rpm/almalinux/bind9.16-libs"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"32:9.16.23-0.16.el8_9.2.alma.1"}]}],"database_specific":{"source":"https://github.com/AlmaLinux/osv-database/blob/master/advisories/almalinux8/ALSA-2024:1781.json"}},{"package":{"name":"bind9.16-license","ecosystem":"AlmaLinux:8","purl":"pkg:rpm/almalinux/bind9.16-license"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"32:9.16.23-0.16.el8_9.2.alma.1"}]}],"database_specific":{"source":"https://github.com/AlmaLinux/osv-database/blob/master/advisories/almalinux8/ALSA-2024:1781.json"}},{"package":{"name":"bind9.16-utils","ecosystem":"AlmaLinux:8","purl":"pkg:rpm/almalinux/bind9.16-utils"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"32:9.16.23-0.16.el8_9.2.alma.1"}]}],"database_specific":{"source":"https://github.com/AlmaLinux/osv-database/blob/master/advisories/almalinux8/ALSA-2024:1781.json"}},{"package":{"name":"python3-bind9.16","ecosystem":"AlmaLinux:8","purl":"pkg:rpm/almalinux/python3-bind9.16"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"32:9.16.23-0.16.el8_9.2.alma.1"}]}],"database_specific":{"source":"https://github.com/AlmaLinux/osv-database/blob/master/advisories/almalinux8/ALSA-2024:1781.json"}}],"schema_version":"1.7.3"}
