Business software giant Oracle is urging customers to update their systems in the October release of its quarterly Critical Patch Update (CPU), which fixes 402 vulnerabilities across various product families.
Well over half (272) of these vulnerabilities open products up to remote exploitation without authentication. That means that the flaw may be exploited over a network without requiring user credentials.
The majority of the flaws are in Oracle Financial Services Applications (53), Oracle MySQL (53), Oracle Communications (52), Oracle Fusion Middleware (46), Oracle Retail Applications (28) and Oracle E-Business Suite (27). But overall, 27 Oracle product families are affected by the flaws. Users can find a patch availability document for each product, available here.
“Oracle continues to periodically receive reports of attempts to maliciously exploit vulnerabilities for which Oracle has already released security patches,” according to the company’s release on Tuesday. “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.”
While details of the flaws themselves are scant, two of the critical vulnerabilities disclosed by Oracle rank the highest severity score – 10 out of 10 – on the CVSS scale.
These include a flaw in the self-service analytics component of Oracle Healthcare Foundation, which is a unified healthcare-analytics platform that is part of the Oracle Health Science Applications suite. The flaw (CVE-2020-1953), which can be remotely exploited without requiring any user credentials, requires no user interaction and is easy to exploit, according to Oracle. Affected supported versions include 7.1.1, 7.2.0, 7.2.1 and 7.3.0.
The second severe flaw (CVE-2020-14871) exists in the pluggable authentication module of Oracle Solaris, its enterprise operating system for Oracle Database and Java applications (part of the Oracle Systems risk matrix). The flaw is also remotely exploitable without user credentials, requires no user interaction and is a “low-complexity” attack. Versions 10 and 11 are affected.
Sixty-five of the vulnerabilities also had a CVSS base score of 9.8 (and six had a score of 9.4) out of 10, making them critical in severity.
Oracle did offer some workarounds, advising that for attacks that require certain privileges or access to certain packages, removing the privileges or the ability to access the packages from users that do not need the privileges may help reduce the risk of successful attack. Users can also reduce the risk of successful attack by blocking network protocols required by an attack.
However, both these approaches may break application functionality, and Oracle does not recommend that either approach be considered a long-term solution as neither corrects the underlying problem.
“Due to the threat posed by a successful attack, Oracle strongly recommends that customers apply Critical Patch Update security patches as soon as possible,” according to the company.
Oracle releases its CPUs on the Tuesday closest to the 17th day of January, April, July and October.
Previous quarterly updates have stomped out hundreds of bugs across the company’s product lines, including one in April that patched 405. There are also out-of-band updates; in June for instance, Oracle warned of a critical remote code-execution flaw in its WebLogic Server being actively exploited in the wild.

What is a ternary operator: The ternary operator is a conditional expression that means this is a comparison operator and results come on a true or false condition and it is the shortest way to writing an if-else statement. It is a condition in a single line replacing the multiline if-else code.
syntax : condition ? value_if_true : value_if_false
condition: A boolean expression evaluates true or false
value_if_true: a value to be assigned if the expression is evaluated to true.
value_if_false: A value to be assigned if the expression is evaluated to false.
How to use ternary operator in python here are some examples of Python ternary operator if-else.
Brief description of examples we have to take two variables a and b. The value of a is 10 and b is 20. find the minimum number using a ternary operator with one line of code. ( **min = a if a < b else b ) **. if a less than b then print a otherwise print b and second examples are the same as first and the third example is check number is even or odd.

So, do you have to become Oracle Certified? it has been a debatable issue for a short time, but one thing is certain: the Oracle Certification provides an accurate measure of your technical abilities.
Additionally, it gives you a foothold over people competing for the database administration positions you desire. Join Oracle online certification course and get complete guidance
Here are the steps to getting an Oracle Database certification:
The first step to getting your Oracle is getting the Associate Certification, which needs that the person passes two tests to become an Oracle Certified Associate (OCA). With this qualification, you’ll add junior management as a team member or an application developer. to urge the associate certification, you’ve got to pass in one among the three tests explained below and therefore the final “Oracle Database 11g: Administration I” test.Join best Oracle online training program to improve your skills.
Step 1: Take one among the subsequent three courses
Oracle Database 12c: SQL Fundamentals 1Z0-061
The examination tests ability to make, retrieve, maintain, and edit data during a database. Mainly, this involves a grasp of important database administration concepts like an electronic database. Additionally, the necessity to know and use SQL is extremely important, because the test would require you to demonstrate your SQL programming skills.
Oracle Database SQL Expert 1Z0-047
In general, this is often a complicated version of the “Introduction to Oracle9i SQL” test. you’ll need proficiency in 76 topics to achieve this exam. you would like to possess a high understanding of database objects, control privileges, and system-level queries. The questions require a deep understanding of SQL, and are multiple parts in nature, requiring the application of concepts instead of mere memorization of answers. Experience in database administration will offer you a notable advantage during this test.
Oracle Database 11g: SQL Fundamentals I 1Z0-051
This test is an improved version of the “Introduction to Oracle9i SQL” test. The content is newer and includes set and conditional operators, which are absent within the older version. Therefore, you’d be happier choosing this test over the previous.
Step 2: Oracle Database 11g: Administration I 1Z0-052
The test requires knowledge on the way to found out database environments and secure Oracle instances in any network environment. Other concepts needed to pass this exam include understanding of database backup and recovery, Oracle Database Architecture, also as the configuration of security instances. The questions require the application of concepts, not just memorization of data.
The professional certification allows you to manage large databases and develop large-scale database applications. In summary, to become an Oracle Certified Professional (OCP), you’ve got to require an instructor-led course, an exam, and a hands-on course.
Step 1: Be an Oracle Certified Associate
You must have the OCA certification as a pre-requisite for this course.
Step 2: Take an Exam
The second step within the OCP certification process is to require a course from a variety of about 50 courses and sit an exam. The list of those courses is out there on the Oracle site. The broad selection means you’ll choose the course that most accurately fits your training requirements. Note that you simply cannot meet the wants of this course through self-study; you’ve got to require an instructor-led class, a virtual class, or learn through training-on-demand.
Step 3: Submission of an Already Completed Course
In this step, you’re required to submit a previously completed course from an inventory of 21 courses. Alternatively, Oracle allows submissions from courses taken within the previous step.
Step 4: Oracle Database 11g: Administration II 1Z0-053
This is the ultimate exam within the OCP certification process. Once you pass this exam, you’ll proceed to the ultimate process.
Step 5: Submit a course completion form
Once you pass this exam, you only need to complete a course submission because of the final step within the OCP certification process.
This is the very best Oracle certification you’ll get. With this qualification, you’ll well-suited to figure in senior levels in IT departments handling sensitive database system issues and applications. you’ll need an OCP certification to urge started. then you’ll take a two-day exam then a hands-on course.
In general, Oracle Certified database administrators have the knowhow to run databases both at the junior and senior levels, counting on the certification level. Some people might argue that there’s little point to being certified because the process involves the memorization of theoretical concepts and taking a multiple-choice test. However, while there’s credence to the very fact that certification does little to catch up on the shortage of technical competence obtained through experience, it does give validity to such claims. As an Oracle Certified database services, potential employers and clients are more easily convinced of your capabilities within the field.

Recently, researchers from Google proposed the solution of a very fundamental question in the machine learning community — What is being transferred in Transfer Learning? They explained various tools and analyses to address the fundamental question.
The ability to transfer the domain knowledge of one machine in which it is trained on to another where the data is usually scarce is one of the desired capabilities for machines. Researchers around the globe have been using transfer learning in various deep learning applications, including object detection, image classification, medical imaging tasks, among others.
