389-ds-base: 389-ds-base: pre-auth LDAP filter injection in CleanAllRUV status check

A flaw was found in 389 Directory Server. An unauthenticated remote attacker can inject LDAP search filters into the CleanAllRUV replication status-check extended operation. Because the handler performs the search against cn=config with elevated replication plugin privileges and returns a boolean...

389-ds-base: 389-ds-base: pre-authentication stack buffer overflow in get_ruvelement_from_berval() via unbounded replica ID parsing

A stack buffer overflow flaw was found in 389 Directory Server 389-ds-base. The getruvelementfromberval function in repl5ruv.c copies digit characters from a network-supplied RUV berval into a fixed 16-byte stack buffer without bounds checking. A remote unauthenticated attacker can crash the LDAP...
