{"id":"AZL-110534","summary":"CVE-2026-96405 affecting package unbound 1.26.1-1","details":"NLnet Labs Unbound up to and including version 1.26.1 limits compression-pointer traversal for each individual domain-name operation but has no aggregate inbound decompression-work budget. Many chained compression pointers in a message results in a lot of CPU usage following them. A malicious actor with recursive-query access and control of an ordinarily delegated authority that serves specially crafted replies can exploit the vulnerability and degrade Unbound's general performance.","modified":"2026-10-23T14:16:37.363379410Z","published":"2026-10-21T09:17:08Z","upstream":["CVE-2026-96405"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-96405"}],"affected":[{"package":{"name":"unbound","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/unbound"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"1.26.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-110534.json"}}],"schema_version":"1.9.0"}
