Critical Patch Update – July 2008

The Critical Patch Update for July 2008 was released on July 15, 2008. Oracle strongly recommends applying the patches as soon as possible.

The Critical Patch Update Advisory is the starting point for relevant information. It includes a list of products affected, pointers to obtain the patches, a summary of the security vulnerabilities, 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 the following location: Oracle Technology Network

The next four Critical Patch Update release dates are:
October 14, 2008
January 13, 2009
April 14, 2009
July 14, 2009

Sincerely,
Oracle Security Alerts

Check and apply the patches if you think it is a needed one.
