MITIGATION
Oracle states:
"Due to the threat posed by a successful attack, Oracle
strongly recommends that customers apply CPU fixes as soon
as possible. Until you apply the CPU fixes, it may be
possible to reduce the risk of successful attack by blocking
network protocols required by an attack. For attacks that
require certain privileges or access to certain packages,
removing the privileges or the ability to access the
packages from users that do not need the privileges may help
reduce the risk of successful attack. Both approaches may
break application functionality, so Oracle strongly
recommends that customers test changes on non-production
systems. Neither approach should be considered a long-term
solution as neither corrects the underlying problem." [1]
