The key word here is flexible: with CoreDNS you are able to do what you want with your DNS data by utilizing plugins.\r\n\r\nSecurity Fix(es):\n\nCoreDNS is a DNS server that chains plugins. Starting in version 1.2.0 and prior to version 1.12.4, the CoreDNS etcd plugin contains a TTL confusion vulnerability where lease IDs are incorrectly used as TTL values, enabling DNS cache pinning attacks. This effectively creates a DoS condition for DNS resolution of affected services. The `TTL()` function in `plugin/etcd/etcd.go` incorrectly casts etcd lease IDs (64-bit integers) to uint32 and uses them as TTL values. Large lease IDs become very large TTLs when cast to uint32. This enables cache pinning attacks. Version 1.12.4 contains a fix for the issue.(CVE-2025-58063)","affected":[{"package":{"ecosystem":"openEuler:20.03-LTS-SP4","name":"coredns","purl":"pkg:rpm/openEuler/coredns&distro=openEuler-20.03-LTS-SP4"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.7.0-1.2.oe2003sp4"}]}],"ecosystem_specific":{"aarch64":["coredns-1.7.0-1.2.oe2003sp4.aarch64.rpm","coredns-help-1.7.0-1.2.oe2003sp4.aarch64.rpm"],"src":["coredns-1.7.0-1.2.oe2003sp4.src.rpm"],"x86_64":["coredns-1.7.0-1.2.oe2003sp4.x86_64.rpm","coredns-help-1.7.0-1.2.oe2003sp4.x86_64.rpm"]}},{"package":{"ecosystem":"openEuler:22.03-LTS-SP4","name":"coredns","purl":"pkg:rpm/openEuler/coredns&distro=openEuler-22.03-LTS-SP4"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.7.0-1.4.oe2203sp4"}]}],"ecosystem_specific":{"aarch64":["coredns-1.7.0-1.4.oe2203sp4.aarch64.rpm","coredns-help-1.7.0-1.4.oe2203sp4.aarch64.rpm"],"src":["coredns-1.7.0-1.4.oe2203sp4.src.rpm"],"x86_64":["coredns-1.7.0-1.4.oe2203sp4.x86_64.rpm","coredns-help-1.7.0-1.4.oe2203sp4.x86_64.rpm"]}},{"package":{"ecosystem":"openEuler:24.03-LTS-SP1","name":"coredns","purl":"pkg:rpm/openEuler/coredns&distro=openEuler-24.03-LTS-SP1"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.7.0-1.4.oe2403sp1"}]}],"ecosystem_specific":{"aarch64":["coredns-1.7.0-1.4.oe2403sp1.aarch64.rpm","coredns-help-1.7.0-1.4.oe2403sp1.aarch64.rpm"],"src":["coredns-1.7.0-1.4.oe2403sp1.src.rpm"],"x86_64":["coredns-1.7.0-1.4.oe2403sp1.x86_64.rpm","coredns-help-1.7.0-1.4.oe2403sp1.x86_64.rpm"]}},{"package":{"ecosystem":"openEuler:24.03-LTS-SP3","name":"coredns","purl":"pkg:rpm/openEuler/coredns&distro=openEuler-24.03-LTS-SP3"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.7.0-1.4.oe2403sp3"}]}],"ecosystem_specific":{"aarch64":["coredns-1.7.0-1.4.oe2403sp3.aarch64.rpm","coredns-help-1.7.0-1.4.oe2403sp3.aarch64.rpm"],"src":["coredns-1.7.0-1.4.oe2403sp3.src.rpm"],"x86_64":["coredns-1.7.0-1.4.oe2403sp3.x86_64.rpm","coredns-help-1.7.0-1.4.oe2403sp3.x86_64.rpm"]}}],"references":[{"type":"ADVISORY","url":"https://www.openeuler.org/zh/security/security-bulletins/detail/?id=openEuler-SA-2026-2720"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-58063"}],"database_specific":{"severity":"High"}}
