The vulnerability allows a remote unauthenticated attacker to cause DoS condition on the target system.
The weakness exists due to improper handling of long search filters with characters that need to be escaped. A remote attacker can submit a specially crafted Lightweight Directory Access Protocol (LDAP) request, trigger buffer overflow and cause the ns-slapd process to crash.
