OpenLDAP is an open source suite of Lightweight Directory Access Protocol (LDAP) applications and development tools. LDAP is a set of protocols used to access and maintain distributed directory information services over an IP network. The openldap package contains configuration files, libraries, and documentation for OpenLDAP.
A denial of service flaw was found in the way the OpenLDAP server daemon (slapd) performed reference counting when using the rwm (rewrite/remap) overlay. A remote attacker able to query the OpenLDAP server could use this flaw to crash the server by immediately unbinding from the server after sending a search request. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2013-4449 to this issue.
More information about these vulnerabilities can be found in the security advisory issued by Red Hat:

Recommended Actions for System Products:
Avaya strongly recommends following networking and
security best practices by implementing firewalls, ACLs,
physical security or other appropriate access restrictions.
Though Avaya believes such restrictions should always be in
place, risk to Avaya products and the surrounding network
from this potential vulnerability may be mitigated by
ensuring these practices are implemented until such time as
an Avaya provided product update or the recommended Avaya
action is applied.
Further restrictions as deemed necessary based on the
customer's security policies may be required during this
interim period, but the System Product operating system or
application should not be modified unless the change is
approved by Avaya. Making changes that are not approved may
void the Avaya product service contract.
When determining risk, Avaya takes into account many factors as outlined by Avaya's Security Vulnerability Classification Policy. The following table describes factors that mitigate the risk of specific vulnerabilities for affected Avaya products:
| Vulnerability | Mitigating Factors |
|---|---|
|
CVE-2013-4449 |
This is a Low risk for Application Enablement Services and Messaging because rwm overlay is not loaded or used by default. This is a Low risk for IQ due to the potential for connections from trusted hosts to crash the slapd, which is a non-critical process. There is no risk for all other products because openldap-servers, which installs slapd, is not installed by default. |
Avaya software-only products operate on general-purpose operating systems. Occasionally vulnerabilities may be discovered in the underlying operating system or applications that come with the operating system. These vulnerabilities often do not impact the software-only product directly but may threaten the integrity of the underlying platform.
In the case of this advisory Avaya software-only products are not affected by the vulnerability directly but the underlying Linux platform may be. Customers should determine on which Linux operating system the product was installed and then follow that vendor's guidance.
| Product: | Actions: |
|---|---|
| Avaya Aura® Application Enablement Services | Depending on the Operating System installed, the affected package may be installed on the underlying Operating System supporting the AES application. |
| CVLAN | Depending on the Operating System installed, the affected package may be installed on the underlying Operating System supporting the CVLAN application. |
| Avaya Aura® Experience Portal | Depending on the Operating System installed, the affected package may be installed on the underlying Operating System supporting the EP application. |
| Avaya Integrated Management Suite (IMS) | Depending on the Operating System installed, the affected package may be installed on the underlying Operating System supporting the IMS application. |
| Avaya Aura® Presence Services | Depending on the Operating System installed, the affected package may be installed on the underlying Operating System supporting the PS application. |
| Avaya Secure Access Link Gateway | Depending on the Operating System installed, the affected package may be installed on the underlying Operating System supporting the SAL Gateway application. |
Recommended Actions for Software-Only Products:
In the event that the affected package is installed, Avaya recommends following recommended actions supplied by Red Hat regarding their Enterprise Linux.
