Multiple implementations of LDAP Directory Server vulnerable to buffer overflow

Vulnerability Note VU#258905

Original Release Date: 2005-01-11 | Last Revised: 2005-01-14

Overview

A buffer overflow in some implementations of the LDAP protocol may allow a remote unauthenticated attacker to execute arbitrary code.

Description

The Lightweight Directory Access Protocol (LDAP) is a protocol for accessing network based directories. A lack of bounds checking in some implementations of the LDAP protocol may allow a buffer used to generate error messages to overflow. If a remote unauthenticated attacker supplies a LDAP server with a specially crafted request, they may be able to trigger the buffer overflow to compromise the vulnerable server.

Impact

A remote unauthenticated attacker may be able to execute arbitrary code on a vulnerable LDAP server with the privileges of the compromised LDAP process, or crash the LDAP process resulting in a denial-of-service condition.

Solution

Users who suspect they are vulnerable are encouraged to check with their vendor to determine the appropriate action to take.

Limit Access

Block or restrict access to the LDAP service (389/tcp or 636/tcp) on affected systems from untrusted networks such as the Internet. Sites, particularly those who are not able to apply the appropriate patches, are encouraged to consider implementing this workaround. Note that this change may break some desired functionality depending on particular site configuration details. As a general rule and a matter of good security practice, the CERT/CC recommends blocking access to all services that are not explicitly required.

OpenLDAP

Notified:  December 09, 2004 Updated:  January 11, 2005

Status

  Not Vulnerable

Vendor Statement

The OpenLDAP Project has evaluated

    • OpenLDAP Software 2.2.17 (current "stable" version) and
    • OpenLDAP Software 2.2.19 (current "release" version)

as well as development and release engineering sources, as distributed by the OpenLDAP Project. We found that long attribute names in LDAP request PDUs do not cause a buffer overflow, nor even lead to unexpected behavior (regardless of whether the long attribute name is defined or not in the subschema).

The OpenLDAP Project did not evaluate older versions of OpenLDAP Software. As these versions are no longer maintained by the OpenLDAP Project, the OpenLDAP Project recommends (irregardless of this issue) that users of these versions consider upgrading to a current version.

The OpenLDAP Project also did not evaluate any 3rd party software, including software based upon (in any fashion) OpenLDAP Software.

Vendor Information

The vendor has not provided us with any further information regarding this vulnerability.
