389 Directory Server before 1.2.11.6 (aka Red Hat Directory Server before 8.2.10-3), after the password for a LDAP user has been changed and before the server has been reset, allows remote attackers to read the plaintext password via the unhashed#user#password attribute.

The remote Redhat Enterprise Linux 5 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2012:1041 advisory.

    Red Hat Directory Server is an LDAPv3 compliant server. The base packages     include the Lightweight Directory Access Protocol (LDAP) server and     command-line utilities for server administration.

    A flaw was found in the way Red Hat Directory Server handled password     changes. If an LDAP user had changed their password, and the directory     server had not been restarted since that change, an attacker able to bind     to the directory server could obtain the plain text version of that user's     password via the unhashed#user#password attribute. (CVE-2012-2678)

    It was found that when the password for an LDAP user was changed, and audit     logging was enabled (it is disabled by default), the new password was     written to the audit log in plain text form. This update introduces a new     configuration parameter, nsslapd-auditlog-logging-hide-unhashed-pw, which     when set to on (the default option), prevents Red Hat Directory Server     from writing plain text passwords to the audit log. This option can be     configured in /etc/dirsrv/slapd-[ID]/dse.ldif. (CVE-2012-2746)

    All users of Red Hat Directory Server 8 are advised to upgrade to these     updated packages, which resolve these issues. After installing this update,     the dirsrv service will be restarted automatically.
