{"id":"AZL-92189","summary":"CVE-2026-14940 affecting package 389-ds-base 3.1.1-11","details":"A heap-buffer-overflow flaw was found in 389 Directory Server (389-ds-base). When\nnormalizing a Distinguished Name (DN) that contains a legacy-quoted value encoding a\nmultivalued nested Relative Distinguished Name (RDN), the server can write past the\nend of a heap allocation while sorting RDN attribute-value pairs. An unauthenticated\nremote attacker can trigger this condition by sending an LDAP operation whose DN\nreaches the DN normalization routine, such as a search with a crafted base DN. This\ncan corrupt heap memory and may cause denial of service.","modified":"2026-08-31T05:26:07Z","published":"2026-07-07T15:16:43Z","upstream":["CVE-2026-14940"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-14940"}],"affected":[{"package":{"name":"389-ds-base","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/389-ds-base"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"3.1.1-11"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-92189.json"}}],"schema_version":"1.9.0"}
