udv@v1 · unaudited · wrong for you until you say what you run

$4.99M is the cost of a breach that happened, from IBM Cost of a Data Breach Report 2026, global average. It is not the value of any asset of yours. That average already covers breaches of every severity, so scaling it by exposure understates a partial-impact record. That is an assumption, not a measurement. Your own asset value goes in the decision record.

Foresight · where to check next

No weakness class or product neighbourhood is held for this record, so this index cannot name anywhere to check next. That is an absence in the record, not a finding about the software.

A rung lights from a row in the index, never from an assessment. "Held sources" is the true scope of the claim: this index reads the CVE record, NVD, CISA KEV, FIRST's EPSS and public proof-of-concept repositories, and it does not observe attacks.

What it is stated by the CNA

A vulnerability was discovered in the 389 Directory Server that allows an unauthenticated attacker with network access to the LDAP port to cause a denial of service. The denial of service is triggered by a single message sent over a TCP connection, no bind or other authentication is required. The message triggers a segmentation fault that results in slapd crashing. receipt
