Be patient! KB4100375. Stay tuned!

If the memory leak is intensive, it can cause the program to crash or even make the whole computer freeze. The most common reason programs have memory leaks is due to a programming error where unused memory is not allocated back to the system.Memory leaks are a class of bugs where the application fails to release memory when no longer needed. A large leak might result in unacceptable response times due to excessive paging. The windows 10  security update (KB4100375) rescheduled because of above reasons.

Microsoft security update – April 10, 2018 – KB4093112

The security update of Microsoft this week included provides support to control usage of Indirect Branch Prediction Barrier (IBPB) within some AMD processors (CPUs) for mitigating CVE-2017-5715. Apart from that it also provides Windows Client Guidance for IT Pros to protect against speculative execution side-channel vulnerabilities. However I was wondering the mitigation plan coverage provided by AMD?

A insidiousness of the SIMD instruction extensions of ARM, MIPS, and x86? Does AMD cover this part because SIMD Instructions considered harmful?Any advice or we just ignore it?

Allen Bradley – The design flaw of the programmable logic controller – system vulnerability

Traditional layer 2 communication system (without TCP/IP), proprietary OS system and without internet technology similar as a antibody protect the important facilities especially electricity power supply, water supply and natural gas facilities. But the element of civilization like a non stop vehicles moving forward. Whereby the man kind went through industrial revolution till today digital technology revolution. Our daily lifes support by electricity, water and natural gas. In order to maintain the stability and quality of those resources of supply. A analogue to digital (electronics) conversion was done, Thereby those facilities are under governance and control by PLC and SCADA today. However a design limitation was found since the components embedded Microsoft operation system and Linux opensource. So we heard power facilities encountered cyber attacks. This time the design flaw found in Allen Bradly PLC product. Regarding to the CVE reference number, we found that the vulnerabilities reported last year and believed that vulnerabilities has been fix. But a reminder to all of us is that vulnerabilities not limit to your office automation system and smartphone.The vulnerabilities are go with us daily.
