389-ds-base: 389-ds-base: unbounded LDAP controls count in get_ldapmessage_controls_ext() causes CPU and heap amplification (remote DoS)

A flaw was found in 389-ds-base. The getldapmessagecontrolsext function in the LDAP server does not enforce an upper bound on the number of controls per LDAP message. A remote, unauthenticated attacker can send a specially crafted LDAP request containing hundreds of thousands of minimal controls...
