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 "Affected Products and Components" 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.
