NULL Pointer Dereference in 389 Directory Server

Publication date: 2026-10-29

Last updated on: 2026-10-29

Assigner: redhat-SADP

Description
A NULL pointer dereference flaw was found in 389-ds-base. This flaw occurs when a ModifyDN (rename) operation uses an attribute's schema alias name (such as "commonName") instead of its canonical name (such as "cn") as the new relative distinguished name. An authenticated attacker with the ModifyDN (rename) permission on the affected entry can use this flaw to crash the directory server, causing a denial of service.
