In certain cases the patches increases or enhances the functionality of the software as well. Example Windows bundle patch. These are the cumulative patches consisting of security fixes. The new name for the critical patch updates is security patch update.
These patches are cumulative for the same product or a component For example Oracle database Critical patch updates or CPUs are released on quarterly basis. Mostly they are released on the third week of January, April, July and October.
The program name which deliver SPUs will still be called critical patch update. These are quarterly cumulative patches that contain security fixes as well as additional fixes sometimes, PSU includes feature enhancements as well. Once the PSU is applied only PSUs can be applied in future quarters until the database is upgraded to knew base version. If you are aiming for only the security fixes then you can go ahead with the CPU or SPU patch application but if you are planning to have the security fixes plus additional fixes and minor version enhancement in that case you should apply Patch Set Update.
Oracle programs for the quarterly releases of security fixes. The patch is released as part of this program may include patch set updates and security updates and bundle patches. The key with PSUs is they are minor version upgrades e. Once a PSU is applied, only PSUs can be applied in future quarters until the database is upgraded to a new base version. For the database, SPUs can not be applied once PSUs have been applied until the database is upgraded to a new base version.
They require a particular base release or patchset to be installed before they can be applied. Each vulnerability is identified by a CVE which is a unique identifier for a vulnerability. Security vulnerabilities are scored using CVSS version 3. Critical Patch Update CPU now refers to the overall release of security fixes each quarter rather than the cumulative database security patch for the quarter.
Think of the CPU as the overarching quarterly release and not as a single patch. Select the appropriate entries for the following fields: Click Search. Select the check box for the patch. Click Download. Click the patch file name, and then click Save. One - off patch bundles provide a fix to specific bugs in one or more releases. You use Mammoth to apply the patch to your cluster. Fixes for the other products that do not receive cumulative fixes are released as one-off patches.
MOPatch is a tool to apply oracle patches, Using this tool we can install multiple oracle patches at single run. It will automate the oracle patching process. OPatch is tools Comes with oracle , which is used to install patches.

Patch Set Update A collection of proactive, stabilizing cumulative patches for a particular product version base release or patch set.
Security Patch Update A security patch update is a cumulative collection of security-related bug fixes. Singleton A patch with one bug fix. Patch Conflict If a patch makes different changes to the same section of code that another OPatch modifies, then these two patches conflict, and only one of them can be installed unless a merge or overlay patch is available.
Superset Patch If a particular patch to be applied contains all of the fixes included in an already installed patch, plus additional fixes, then the patch with more fixes is a superset patch, and there is no conflict. Combination Conflict If a patch to be installed conflicts with more than one already installed patch, this is considered a combination conflict.
