{"id":"RLSA-2024:3271","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\n* bind9: KeyTrap - Extreme CPU consumption in DNSSEC validator (CVE-2023-50387)\n\n* bind9: Preparing an NSEC3 closest encloser proof can exhaust CPU resources (CVE-2023-50868)\n\nBug Fix:\n\n* dhcp rebuilt after API change of bind-export-libs\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":"2026-03-11T06:31:12.426346Z","published":"2024-06-14T13:59:16.809606Z","upstream":["CVE-2023-4408","CVE-2023-50387","CVE-2023-50868"],"references":[{"type":"ADVISORY","url":"https://errata.rockylinux.org/RLSA-2024:3271"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2263896"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2263914"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2263917"}],"affected":[{"package":{"name":"bind","ecosystem":"Rocky Linux:8","purl":"pkg:rpm/rocky-linux/bind?distro=rocky-linux-8&epoch=2"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2:9.11.36-14.el8_10"}],"database_specific":{"yum_repository":"BaseOS"}}],"database_specific":{"source":"https://storage.googleapis.com/resf-osv-data/RLSA-2024:3271.json"}},{"package":{"name":"dhcp","ecosystem":"Rocky Linux:8","purl":"pkg:rpm/rocky-linux/dhcp?distro=rocky-linux-8&epoch=2"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2:4.3.6-50.el8_10"}],"database_specific":{"yum_repository":"BaseOS"}}],"database_specific":{"source":"https://storage.googleapis.com/resf-osv-data/RLSA-2024:3271.json"}}],"schema_version":"1.7.5","credits":[{"name":"Rocky Enterprise Software Foundation"},{"name":"Red Hat"}]}
