Summary

A flaw was found in the 389 Directory Server. This flaw allows an unauthenticated user to cause a systematic server crash while sending a specific extended search request, leading to a denial of service.

The vulnerability is limited to service availability, meaning the server can crash and become temporarily unavailable, but no data is leaked, altered, or accessed by unauthorized users.

Additionally, recovery from this condition typically involves restarting the service, which can be automated or handled through monitoring tools, thus limiting the long-term impact. Since the flaw does not facilitate unauthorized access or privilege escalation, it is considered moderate in severity.

Red Hat severity: Moderate — CVSS 6.5 (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H). Weakness: CWE-230.

Affected Red Hat products: Red Hat Directory Server 12.4 for RHEL 9; Red Hat Enterprise Linux 9. Red Hat fixing advisory: RHSA-2024:4997, RHSA-2024:5192.

Affected products named by the advisory: Red Hat package: 389-ds-base.
