Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The remote Oracle Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2016-2765 advisory.

    - Resolves: #1358559 - CVE-2016-4992 389-ds-base: Information disclosure via repeated use of LDAP ADD     operation
    - Resolves: #1361421 - CVE-2016-5416 389-ds-base: ACI readable by anonymous user (DS 48354)
    - Resolves: #1360974 - CVE-2016-5405 389-ds-base: Password verification vulnerable to timing attack

Tenable has extracted the preceding description block directly from the Oracle Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2016:2594 advisory.

    389 Directory Server is an LDAP version 3 (LDAPv3) compliant server. The base packages include the     Lightweight Directory Access Protocol (LDAP) server and command-line utilities for server administration.

    The following packages have been upgraded to a newer upstream version: 389-ds-base (1.3.5.10).
    (BZ#1270020)

    Security Fix(es):

    * It was found that 389 Directory Server was vulnerable to a flaw in which the default ACI (Access Control     Instructions) could be read by an anonymous user. This could lead to leakage of sensitive information.
    (CVE-2016-5416)

    * An information disclosure flaw was found in 389 Directory Server. A user with no access to objects in     certain LDAP sub-tree could send LDAP ADD operations with a specific object name. The error message     returned to the user was different based on whether the target object existed or not. (CVE-2016-4992)

    * It was found that 389 Directory Server was vulnerable to a remote password disclosure via timing attack.
    A remote attacker could possibly use this flaw to retrieve directory server password after many tries.
    (CVE-2016-5405)

    The CVE-2016-5416 issue was discovered by Viktor Ashirov (Red Hat); the CVE-2016-4992 issue was discovered     by Petr Spacek (Red Hat) and Martin Basti (Red Hat); and the CVE-2016-5405 issue was discovered by William     Brown (Red Hat).

CVE-2016-5405 389-ds-base: Password verification vulnerable to timing attack

It was found that 389 Directory Server was vulnerable to a remote password disclosure via timing attack. A remote attacker could possibly use this flaw to retrieve directory server password after many tries.

CVE-2016-5416 389-ds-base: ACI readable by anonymous user

It was found that 389 Directory Server was vulnerable to a flaw in which the default ACI (Access Control Instructions) could be read by an anonymous user. This could lead to leakage of sensitive information.

CVE-2016-4992 389-ds-base: Information disclosure via repeated use of LDAP ADD operation

An information disclosure flaw was found in 389 Directory Server. A user with no access to objects in certain LDAP sub-tree could send LDAP ADD operations with a specific object name. The error message returned to the user was different based on whether the target object existed or not.

An update for 389-ds-base is now available for Red Hat Enterprise Linux 6.

Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

389 Directory Server is an LDAP version 3 (LDAPv3) compliant server.
The base packages include the Lightweight Directory Access Protocol (LDAP) server and command-line utilities for server administration.

Security Fix(es) :

* It was found that 389 Directory Server was vulnerable to a flaw in which the default ACI (Access Control Instructions) could be read by an anonymous user. This could lead to leakage of sensitive information. (CVE-2016-5416)

* An information disclosure flaw was found in 389 Directory Server. A user with no access to objects in certain LDAP sub-tree could send LDAP ADD operations with a specific object name. The error message returned to the user was different based on whether the target object existed or not. (CVE-2016-4992)

* It was found that 389 Directory Server was vulnerable to a remote password disclosure via timing attack. A remote attacker could possibly use this flaw to retrieve directory server password after many tries. (CVE-2016-5405)

The CVE-2016-5416 issue was discovered by Viktor Ashirov (Red Hat);
the CVE-2016-4992 issue was discovered by Petr Spacek (Red Hat) and Martin Basti (Red Hat); and the CVE-2016-5405 issue was discovered by William Brown (Red Hat).

Bug Fix(es) :

* Previously, a bug in the changelog iterator buffer caused it to point to an incorrect position when reloading the buffer. This caused replication to skip parts of the changelog, and consequently some changes were not replicated. This bug has been fixed, and replication data loss due to an incorrectly reloaded changelog buffer no longer occurs. (BZ#1354331)

* Previously, if internal modifications were generated on a consumer (for example by the Account Policy plug-in) and additional changes to the same attributes were received from replication, a bug caused Directory Server to accumulate state information on the consumer. The bug has been fixed by making sure that replace operations are only applied if they are newer than existing attribute deletion change sequence numbers (CSNs), and state information no longer accumulates in this situation. (BZ#1379599)

Enhancement(s) :

* In a multi-master replication environment where multiple masters receive updates at the same time, it was previously possible for a single master to obtain exclusive access to a replica and hold it for a very long time due to problems such as a slow network connection.
During this time, other masters were blocked from accessing the same replica, which considerably slowed down the replication process. This update adds a new configuration attribute, 'nsds5ReplicaReleaseTimeout', which can be used to specify a timeout in seconds. After the specified timeout period passes, the master releases the replica, allowing other masters to access it and send their updates. (BZ#1358390)

Security Fix(es) :

  - It was found that 389 Directory Server was vulnerable to     a flaw in which the default ACI (Access Control     Instructions) could be read by an anonymous user. This     could lead to leakage of sensitive information.
