{"id":"ALSA-2024:1782","summary":"Important: bind and dhcp 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\nThe Dynamic Host Configuration Protocol (DHCP) is a protocol that allows individual devices on an IP network to get their own network configuration information, including an IP address, a subnet mask, and a broadcast address. The dhcp packages provide a relay agent and ISC DHCP service required to enable and administer DHCP on a network.\n\nSecurity Fix(es):\n\n* bind9: Parsing large DNS messages may cause excessive CPU load (CVE-2023-4408)\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":"2026-02-04T03:34:01.854807Z","published":"2024-04-12T00:00:00Z","related":["CVE-2023-4408","CVE-2023-50387","CVE-2023-50868"],"references":[{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2024:1782"},{"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://bugzilla.redhat.com/2263896"},{"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-2024-1782.html"}],"affected":[{"package":{"name":"bind","ecosystem":"AlmaLinux:8","purl":"pkg:rpm/almalinux/bind"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"32:9.11.36-11.el8_9.1"}]}],"database_specific":{"source":"https://github.com/AlmaLinux/osv-database/blob/master/advisories/almalinux8/ALSA-2024:1782.json"}},{"package":{"name":"bind-chroot","ecosystem":"AlmaLinux:8","purl":"pkg:rpm/almalinux/bind-chroot"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"32:9.11.36-11.el8_9.1"}]}],"database_specific":{"source":"https://github.com/AlmaLinux/osv-database/blob/master/advisories/almalinux8/ALSA-2024:1782.json"}},{"package":{"name":"bind-devel","ecosystem":"AlmaLinux:8","purl":"pkg:rpm/almalinux/bind-devel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"32:9.11.36-11.el8_9.1"}]}],"database_specific":{"source":"https://github.com/AlmaLinux/osv-database/blob/master/advisories/almalinux8/ALSA-2024:1782.json"}},{"package":{"name":"bind-export-devel","ecosystem":"AlmaLinux:8","purl":"pkg:rpm/almalinux/bind-export-devel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"32:9.11.36-11.el8_9.1"}]}],"database_specific":{"source":"https://github.com/AlmaLinux/osv-database/blob/master/advisories/almalinux8/ALSA-2024:1782.json"}},{"package":{"name":"bind-export-libs","ecosystem":"AlmaLinux:8","purl":"pkg:rpm/almalinux/bind-export-libs"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"32:9.11.36-11.el8_9.1"}]}],"database_specific":{"source":"https://github.com/AlmaLinux/osv-database/blob/master/advisories/almalinux8/ALSA-2024:1782.json"}},{"package":{"name":"bind-libs","ecosystem":"AlmaLinux:8","purl":"pkg:rpm/almalinux/bind-libs"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"32:9.11.36-11.el8_9.1"}]}],"database_specific":{"source":"https://github.com/AlmaLinux/osv-database/blob/master/advisories/almalinux8/ALSA-2024:1782.json"}},{"package":{"name":"bind-libs-lite","ecosystem":"AlmaLinux:8","purl":"pkg:rpm/almalinux/bind-libs-lite"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"32:9.11.36-11.el8_9.1"}]}],"database_specific":{"source":"https://github.com/AlmaLinux/osv-database/blob/master/advisories/almalinux8/ALSA-2024:1782.json"}},{"package":{"name":"bind-license","ecosystem":"AlmaLinux:8","purl":"pkg:rpm/almalinux/bind-license"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"32:9.11.36-11.el8_9.1"}]}],"database_specific":{"source":"https://github.com/AlmaLinux/osv-database/blob/master/advisories/almalinux8/ALSA-2024:1782.json"}},{"package":{"name":"bind-lite-devel","ecosystem":"AlmaLinux:8","purl":"pkg:rpm/almalinux/bind-lite-devel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"32:9.11.36-11.el8_9.1"}]}],"database_specific":{"source":"https://github.com/AlmaLinux/osv-database/blob/master/advisories/almalinux8/ALSA-2024:1782.json"}},{"package":{"name":"bind-pkcs11","ecosystem":"AlmaLinux:8","purl":"pkg:rpm/almalinux/bind-pkcs11"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"32:9.11.36-11.el8_9.1"}]}],"database_specific":{"source":"https://github.com/AlmaLinux/osv-database/blob/master/advisories/almalinux8/ALSA-2024:1782.json"}},{"package":{"name":"bind-pkcs11-devel","ecosystem":"AlmaLinux:8","purl":"pkg:rpm/almalinux/bind-pkcs11-devel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"32:9.11.36-11.el8_9.1"}]}],"database_specific":{"source":"https://github.com/AlmaLinux/osv-database/blob/master/advisories/almalinux8/ALSA-2024:1782.json"}},{"package":{"name":"bind-pkcs11-libs","ecosystem":"AlmaLinux:8","purl":"pkg:rpm/almalinux/bind-pkcs11-libs"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"32:9.11.36-11.el8_9.1"}]}],"database_specific":{"source":"https://github.com/AlmaLinux/osv-database/blob/master/advisories/almalinux8/ALSA-2024:1782.json"}},{"package":{"name":"bind-pkcs11-utils","ecosystem":"AlmaLinux:8","purl":"pkg:rpm/almalinux/bind-pkcs11-utils"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"32:9.11.36-11.el8_9.1"}]}],"database_specific":{"source":"https://github.com/AlmaLinux/osv-database/blob/master/advisories/al
