A bug in a computer system is a discrepancy in a how a program is meant to act or operate, often caused by a programming error or oversight in how the system can actually be used. Viruses
written by hackers
routinely make use of bugs in software in order to exploit them for their own ends. Often leading to abuse, unpatched, or "buggy" software puts a user's sensitive information at risk of theft or the system itself open to malicious attacks. If a bug is left unfixed, depending on its severity, it can be used to subvert access controls and other safeguards built in to a system.
