The majority of the fixes are for flaws in business products such as Oracle E-Business Suite, Oracle Fusion Middleware, Oracle PeopleSoft, Oracle Retail Applications, Oracle JD Edwards, Oracle Supply Chain Products, and Oracle Database Server.

E-Business Suite, which is used by companies to store key data and manage a wide range of business processes, accounts for more than 40 percent of the patched vulnerabilities—121. Out of these, 118 are remotely exploitable and the highest rated one has a score of 9.2 (critical) in the Common Vulnerability Scoring System.

Another 37 vulnerabilities were patched in Oracle Financial Services, 18 in Oracle Fusion Middleware, eight in Oracle Retail Applications, eight in Oracle PeopleSoft and 4 in the Oracle Primavera Products Suite. These products are used across a variety of industries.
