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.","dates":{"published":"2026-07-07T13:54:20.688Z","modified":"2026-07-07T15:35:45.502Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":5.3,"severity":"medium","version":"3.1","versionLabel":"v3.1","source":"CVE.org","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","score":5.3,"severity":"medium","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"OSV
