Summary: An unauthenticated user can cause a systematic server crash while sending a specific extended search request.

Description: 389-ds-base in RHEL 9.4 - RHDS 12.4, supports a new matching rule (inchain or 1.2.840.113556.1.4.1941). This matching rule requires that the matching attribute has a DN syntax. If the attribute in the ldap client request is not DN syntax, the server logs a message. The format of the message requires an attribute but as the attribute is missing, it triggers a SEGV.
