Software without 'a' single bug....! What you are thinking...? Is it possible? A bug is an error, flaw, mistake, failure, or fault in a computer program that prevents it from behaving as intended . If you are in a software development field then you definitely know about this name call Bug. Sometime you might get irritation on this name, because you might had got several terrible experiences in BUG FIXING in your workplace.

It is common practice for software to be released with known bugs that are considered non-critical. It is quite obvious and not an important fact that software may contain some numbers of known bugs when shipped, measurements during the testing may provide a statistically reliable estimate of the number of likely bugs remaining. These is because of the marketing strategy of that software. While software development team wasting the time to fix on that known bugs, others may get the chance to capture that market. So that is why I said it is an obvious thing in Software market. This list inform users about bugs that are not fixed in the current release, or not fixed at all, and often a workaround is offered additionally.

But some time there are some unknown bugs in the software that may lead to exploit unknown vulnerabilities in a system. That can lead to security holes or vulnerable areas that can be targeted by cyber criminals.
Today the US National Security Agency has published a list of the world's most dangerous coding mistakes. The Experts quoted that many of these errors are not well understood by programmers. Here I put that TOP 25 MOST DANGEROUS PROGRAMMING ERRORS which are categorized by US National Security Agency.
