Critical Patch Updates
Oracle regularly releases critical patch updates. These patches are created to resolve a bug or glitch in the system, or to increase the security and effectiveness of the system. It's important to take note of these updates because it can have an impact on how the applications and databases will react to different vulnerabilities.
If you fail to apply new Oracle patches, your system could be left vulnerable to attacks or threats. The new critical patch update contains new security fixes across product families such as Oracle Database, Oracle Application Server, and Oracle DB UM Connector for Oracle Identity Manager, among others.
Why you should apply the critical patch update now
Critical Patch Updates include all fixes for a product from the previous Critical Patch Updates.
Patching has always been one of the many joys (or dreads) of Oracle DBAs. Ever since the initial days of Oracle, patches have been published by Oracle Support, downloaded by DBAs (very early on, via posted floppy disks or CDs), and then applied to the target database - whether to fix minor database bugs; apply security fixes; or upgrade the database from one patch version to the other.
