It was found that when replication was enabled for each attribute in 389 Directory Server, which is the default configuration, the server returned replicated metadata when the directory was searched while debugging was enabled. A remote attacker could use this flaw to disclose potentially sensitive information.
Run yum update 389-ds-base to update your system.
