It was found that the uniqueness_entry_to_config() function, used by the 'attribute uniqueness' plugin of 389 Directory Server, did not properly NULL terminate an array used in some configuration. An authenticated, or possibly unauthenticated, attacker could use this flaw to force an out-of-bound heap memory read, possibly triggering a crash of the LDAP service.(CVE-2017-2591)");
