Critical Patch Update is a collection of patches for multiple
security vulnerabilities. These patches are usually cumulative, but each
advisory describes only the security patches added since the previous
Critical Patch Update advisory. Thus, prior Critical Patch Update
advisories should be reviewed for information regarding earlier
published security patches. Please refer to:
- Critical Patch Updates, Security Alerts and Bulletins for information about Oracle Security Advisories.
Oracle continues to periodically receive reports of attempts
to maliciously exploit vulnerabilities for which Oracle has already
released security patches. In some instances, it has been reported that
attackers have been successful because targeted customers had failed to
apply available Oracle patches. Oracle therefore strongly recommends
that customers remain on actively-supported versions and apply Critical
Patch Update security patches without delay.
This Critical Patch Update contains 334 new security patches across
the product families listed below. Please note that an MOS note
summarizing the content of this Critical Patch Update and other Oracle
Software Security Assurance activities is located at January 2020 Critical Patch Update: Executive Summary and Analysis.
