Title: OpenLDAP Denial of Service Vulnerabilities
Severity: MODERATE
Description:
The Lightweight Directory Access Protocol (LDAP) is designed to be a lightweight access protocol for directory services supporting X.500 models. It offers a means of searching, fetching and manipulating directory content.
Several input validation errors have been found to exist in OpenLDAP. The problems were discovered using the PROTOS project's LDAPv3 test suite, which tests the security of a server by presenting it with a wide variety of sample packets containing unexpected values or illegally formatted data. Specifically, the vulnerabilities were found during tests from the "Encoding" section of the test suite, which tests an LDAP server's response to packets that violate the Basic Encoding Rules (BER).
The problems enable remote attackers to cause an affected OpenLDAP server to crash, resulting in a denial of service condition.
Further technical details are not available at this time.
