Discussion

PowerDNS LDAP Backend Query Escape Failure Vulnerability

The PowerDNS LDAP back-end did not adequately escape requests prior to version 2.9.18. As a result, it was possible for requests to fail without answering questions. This may have security implications in environments where PowerDNS and LDAP are used. The vendor has fixed this in version 2.9.18.
