A Critical Patch Update is a collection of patches for multiple security vulnerabilities. These patches address vulnerabilities in Oracle code and in third-party components included in Oracle products. 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. Refer to “Critical Patch Updates, Security Alerts and Bulletins” for information about Oracle Security advisories.
Starting with the October 2020 Critical Patch Update, Oracle lists updates that address vulnerabilities in third-party components which are not exploitable in the context of their inclusion in their respective Oracle product beneath the product's risk matrix. Oracle has published two versions of the October 2020 Critical Patch Update Advisory: this version of the advisory implemented the change in how non-exploitable vulnerabilities in third-party components are reported, and the “traditional” advisory follows the same format as the previous advisories. The “traditional” advisory is published at <https://www.oracle.com/security-alerts/cpuoct2020traditional.html>.
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 403 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 October 2020 Critical Patch Update: Executive Summary and Analysis.
