Affected products including Enterprise Manager, Java SE, MySQL, JD Edwards, Oracle Supply Chain Products, Database, E-Business Suite, Retail Applications, Virtualization, Oracle Banking Platform and more.
Oracle said, Critical Patch Update patches are usually cumulative, but each advisory describes only the security fixes added since the previous Critical Patch Update advisory.
There is some earlier instance, the attacker has been exploited some of the vulnerabilities in Oracle products because targeted customers had failed to apply available Oracle patches.
All 284 are fixed and released the updates so now Oracle strongly recommends that customers remain on actively-supported versions and apply Critical Patch Update fixes without delay.
Some of the vulnerabilities are potentially exploited to the system that allows an attacker to take over the complete control of the vulnerable system. so applying the patch as soon as possible will reduce the risk of successful attack by blocking network protocols required by an attack.
In this case, several vulnerabilities addressed in this Critical Patch Update affect multiple products and the CVE has been assigned for each vulnerability.
Here you can find the complete list of Affected Products and Patch Information.
According to Oracle, “Oracle conducts an analysis of each security vulnerability addressed by a Critical Patch Update. 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”
