From Oracle Support -
The Critical Patch Update for April 2010 was released on April 13, 2010. Oracle strongly recommends applying the patches as soon as possible.
Please note that we have added Sun products to this Critical Patch Update.
The Critical Patch Update Advisory is the starting point for relevant information. It includes the list of products affected, pointers to obtain the patches, a summary of the security vulnerabilities for each product suite, and links to other important documents. Supported products that are not listed in the “Supported Products and Components Affected” section of the advisory do not require new patches to be applied.
Also, it is essential to review the Critical Patch Update supporting documentation referenced in the Advisory before applying patches, as this is where you can find important pertinent information.
The Critical Patch Update Advisory is available at any of the following locations:
Oracle Technology Network: http://www.oracle.com/technology/deploy/security/alerts.htm
