Red Hat Directory Server is vulnerable to Denial Of Service (DoS). Ulf Weltman of Hewlett Packard discovered a flaw in the way Directory Server handled LDAP search requests with patterns. A remote attacker with access to the LDAP service could create a search request that, when the search pattern was matched against specially crafted data records, caused Directory Server to use a large amount of CPU time because the Directory Server did not impose time limits on such search requests. In this updated package, Directory Server imposes the nsslapd-timelimit attribute on the pattern-search query run times. This attribute has the default limit of 3600 seconds; to shorten this limit, use ldapmodify to change the nsslapd-timelimit value in the cn=config entry.
