A software bug is a bug in computer software. A computer program with many or serious bugs may be described as buggy. The effects of a software bug range from minor (i.e. a misspelled word in the user interface) to severe (i.e. crash or hang). Software bugs have been linked to disasters.
A bug bounty program is a deal offered by many websites, organizations, and software developers by which individuals can receive recognition and compensation for reporting bugs, especially those pertaining to security exploits and vulnerabilities.
Many software bugs are merely annoying or inconvenient, but some can have extremely serious consequences—either financially or as a threat to human well-being. The following is a list of software bugs with significant consequences.
In engineering, debugging is the process of finding the root cause of and workarounds and possible fixes for bugs . For software, debugging tactics can involve interactive debugging, control flow analysis, log file analysis, monitoring at the application or system level, memory dumps, and profiling.
In computer programming, a logic error is a bug in a program that causes it to operate incorrectly, but not to terminate abnormally (or crash ). A logic error produces unintended or undesired output or other behaviour, although it may not immediately be recognized as such.
Patch (computing) A patch is a set of changes to a computer program or its supporting data designed to update or repair it. [1] This includes bugfixes or bug fixes to remove security vulnerabilities [1] and correct bugs (errors). [2] [better source needed] Patches are often written to improve the functionality, usability, or performance of a ...
Defensive programming is a form of defensive design intended to develop programs that are capable of detecting potential security abnormalities and make predetermined responses. [1] It ensures the continuing function of a piece of software under unforeseen circumstances.
In programming and software development, fuzzing or fuzz testing is an automated software testing technique that involves providing invalid, unexpected, or random data as inputs to a computer program. The program is then monitored for exceptions such as crashes, failing built-in code assertions, or potential memory leaks.
Automatic bug-fixing is the automatic repair of software bugs without the intervention of a human programmer. It is also commonly referred to as automatic patch generation, automatic bug repair, or automatic program repair.
Stack buffer overflow is a type of the more general programming malfunction known as buffer overflow (or buffer overrun). [1] Overfilling a buffer on the stack is more likely to derail program execution than overfilling a buffer on the heap because the stack contains the return addresses for all active function calls.
