## Description

A flaw was found in RHDS 11 and RHDS 12. While browsing entries LDAP tries
to decode the userPassword attribute instead of the userCertificate
attribute which could lead into sensitive information leaked. An attacker
with a local account where the cockpit-389-ds is running can list the
processes and display the hashed passwords. The highest threat from this
vulnerability is to data confidentiality.
