Last Revised: June 21, 2013
Number: ASA-2010-237
Risk Level: Low
Advisory Version: 7.0
Advisory Status: Final

1. Overview:

OpenLDAP is an open source suite of LDAP (Lightweight Directory Access Protocol) applications and development tools.

Multiple flaws were discovered in the way the slapd daemon handled modify relative distinguished name (modrdn) requests. An authenticated user with privileges to perform modrdn operations could use these flaws to crash the slapd daemon via specially-crafted modrdn requests. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the names CVE-2010-0211 and CVE-2010-0212 to these issues.

More information about these vulnerabilities can be found in the security advisory issued by RedHat Linux:

Recommended Actions for System Products:
Avaya strongly recommends that customers follow 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's product and the surrounding network from this potential vulnerability may be mitigated by ensuring these practices are implemented until such time as a product update is available or the recommended action is applied. Further restrictions as deemed necessary based on the customer's security policies may be required during this interim period.

3. Avaya Software-Only Products:

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.
