Vulnerability Note VU#657547
Critical Path directory products contain multiple vulnerabilities in LDAP handling code
Multiple Critical Path directory products contain 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 InJoin Directory Server and LiveContent Directory both contain multiple vulnerabilities in the code that processes LDAP requests. These vulnerabilities were discovered independently by Critical Path using the PROTOS LDAPv3 test suite.
The tests conducted by Critical Path demonstrated failures in both the encoding and application sections of the test suite.
These vulnerabilities allow a remote attacker to crash affected Critical Path directory servers, resulting in a denial-of-service condition. They may also allow a remote attacker to execute arbitrary code with the privileges of the directory server. The server typically runs with system privileges.
