Risk Matrix Content

Risk matrices list only security vulnerabilities that are newly fixed by the patches associated with this advisory. Risk matrices for previous security fixes can be found in previous Critical Patch Update advisories and Alerts. An English text version of the risk matrices provided in this document is here.

Security vulnerabilities are scored using CVSS version 3.0 (see Oracle CVSS Scoring for an explanation of how Oracle applies CVSS version 3.0).

Oracle conducts an analysis of each security vulnerability addressed by a Security Alert. Oracle does not disclose detailed information about this security analysis to customers, but the resulting Risk Matrix and associated documentation provide information about the type of vulnerability, the conditions required to exploit it, and the potential impact of a successful exploit. Oracle provides this information, in part, so that customers may conduct their own risk analysis based on the particulars of their product usage. For more information, see Oracle vulnerability disclosure policies.

The protocol in the risk matrix implies that all of its secure variants (if applicable) are affected as well. For example, if HTTP is listed as an affected protocol, it implies that HTTPS (if applicable) is also affected. The secure variant of a protocol is listed in the risk matrix only if it is the only variant affected, e.g. HTTPS will typically be listed for vulnerabilities in SSL and TLS.
