The Oracle Internet Directory server contains vulnerabilities that may allow denial-of-service attacks, unauthorized privileged access, or both. These vulnerabilities were revealed using the PROTOS LDAPv3 test suite and are documented in CERT Advisory CA-2001-18. If your site uses this product, the CERT/CC encourages you to follow the advice provided below.
The Oracle Internet Directory server contains multiple vulnerabilities in the code used to process LDAP requests.
In the encoding section of the test suite, this product failed an indeterminate number of test cases in the group that tests a server’s response to invalid encodings of BER OBJECT-IDENTIFIER values.
In the application section of the test suite, this product failed 46 of 77 groups. These results suggest that both buffer overflow and format string vulnerabilities are likely to be present in a variety of application components.
One or more of these vulnerabilities allow a remote attacker to execute arbitrary code with the privileges of the Oracle server. The server typically runs with system privileges. At least one of these vulnerabilities has been successfully exploited in a laboratory environment.

Block access to directory services at network perimeter
As a temporary measure, it is possible to limit the scope of these vulnerabilities by blocking access to directory services at the network perimeter. Please note that this workaround does not protect vulnerable products from internal attacks.
