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 (such as a misspelled word in the user interface) to severe (such as frequent crashing ). Software bugs have been linked to disasters.
A hardware bug is a bug in computer hardware. It is the hardware counterpart of software bug, a defect in software . A bug is different from a glitch which describes an undesirable behavior as more quick, transient and repeated than constant, and different from a quirk which is a behavior that may be considered useful even though not ...
The Corrupted Blood incident was a software bug in World of Warcraft that caused a deadly, debuff -inducing virtual disease that could only be contracted during a particular raid to be set free into the rest of the game world, leading to numerous, repeated deaths of many player characters.
Computer hacking. Vulnerabilities are flaws in a computer system that weaken the overall security of the system. Despite intentions to achieve complete correctness, virtually all hardware and software contains bugs where the system does not behave as expected. If the bug could enable an attacker to compromise the confidentiality, integrity, or ...
A computer exploit is a type of malware that takes advantage of bugs or vulnerabilities, which cybercriminals use to gain illicit access to a system. These vulnerabilities are hidden in the code of the operating system and its applications just waiting to be discovered and put to use by cybercriminals. Commonly exploited software includes the ...
Patch (computing) A patch is data that is intended to be used to modify an existing software resource such as a program or a file, often to fix bugs and security vulnerabilities. [1] [2] A patch may be created to improve functionality, usability, or performance. A patch is typically provided by a vendor for updating the software that they provide.
The vulnerability is known to affect Skylake and later processors from Intel and Zen-based processors from AMD. [ 54] In February 2023, a team of researchers at North Carolina State University uncovered a new code execution vulnerability called Spectre-HD, also known as "Spectre SRV" or "Spectre v6".
Stack exhaustion – occurs when a program runs out of stack space, typically because of too deep recursion. A guard page typically halts the program, preventing memory corruption, but functions with large stack frames may bypass the page. Heap exhaustion – the program tries to allocate more memory than the amount available. In some languages ...
