Both approaches may break application functionality, so Oracle strongly recommends that customers test changes on non- production systems. For attacks that require certain privileges or access to certain packages, removing the privileges or the ability to access the packages from unprivileged users may help reduce the risk of successful attack. Until you apply the CPU fixes, it may be possible to reduce the risk of successful attack by restricting network protocols required by an attack. Workaroundsĭue to the threat posed by a successful attack, Oracle strongly recommends that customers apply CPU fixes as soon as possible. ![]() Finally, Oracle does not distribute exploit code or “proof-of-concept” code for product vulnerabilities. ![]() Oracle does not provide advance notification on CPUs or Security Alerts to individual customers. Oracle will not provide additional information about the specifics of vulnerabilities beyond what is provided in the CPU or Security Alert notification, the Patch Availability Document, the readme files, and FAQs. As a matter of policy, Oracle does not disclose detailed information about an exploit condition or results that can be used to conduct 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. Oracle does not disclose information about the security analysis, but the resulting Risk Matrix and associated documentation provide information about the type of vulnerability, the conditions required to exploit it, and the potential result of a successful exploit. Oracle conducts an analysis of each security vulnerability addressed by a Critical Patch Update (CPU). Security vulnerabilities are scored using CVSS version 2.0 (see Oracle CVSS Scoring for an explanation of how Oracle applies CVSS 2.0). Risk matrices for previous security fixes can be found in previous Critical Patch Update advisories. The risk matrix lists only security vulnerabilities that are newly fixed by the patches associated with this advisory.
