Due to the threat posed by a successful attack, Oracle strongly recommends that customers apply CPU fixes as soon as possible. This Critical Patch Update contains 66 new security fixes across all product families listed.

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.

Oracle products may have dependencies on other Oracle products. Hence security vulnerability fixes announced in this Critical Patch Update may affect one or more dependent Oracle products.

Oracle proactively creates patches only for platform/version combinations that, based on historical data, customers are likely to download for the next Critical Patch Update. Patches for historically inactive platform/version combinations of the Oracle Database, Oracle Application Server and Enterprise Manager will be created only if requested by customers.Refer to Patch Set Update and Critical Patch Update April 2011 Availability Documentation for further details regarding the On Request patches.


Oracle Critical Patch Update (CPU) is a bundle of patches released on a quarterly basis to provide security fixes for Oracle products.

For each administered Oracle product, consult the documentation for patch availability information and installation instructions referenced from the following table.
