In other cases resource leaks can be a major problem, causing resource starvation and severe system slowdown or instability, crashing the leaking process, other processes, or even the system. [2] Resource leaks often go unnoticed under light load and short runtimes, and these problems only manifest themselves under heavy system load or systems ...
A memory leak may also happen when an object is stored in memory but cannot be accessed by the running code (i.e. unreachable memory). [2] A memory leak has symptoms similar to a number of other problems and generally can only be diagnosed by a programmer with access to the program's source code.
Minecraft mods have been an attack vector of malware by downloading and running malicious mods. [52] [53] In March 2017, Slovak cyber company ESET revealed that 87 examples of trojan horse malware were distributed through the Google Play Store under the guise of Minecraft mods. Their purpose was to either display adverts or con players into ...
Automatic memory management in the form of garbage collection is the most common technique for preventing some of the memory safety problems, since it prevents common memory safety errors like use-after-free for all data allocated within the language runtime. [11]
Resource exhaustion attacks are computer security exploits that crash, hang, or otherwise interfere with the targeted program or system.They are a form of denial-of-service attack but are different from distributed denial-of-service attacks, which involve overwhelming a network host such as a web server with requests from many locations.
A handle leak is a type of software bug that occurs when a computer program asks for a handle to a resource but does not free the handle when it is no longer used. [1] If this occurs frequently or repeatedly over an extended period of time, a large number of handles may be marked in-use and thus unavailable, causing performance problems or a ...
A zero-day (also known as a 0-day) is a vulnerability in software or hardware that is typically unknown to the vendor and for which no patch or other fix is available. The vendor thus has zero days to prepare a patch, as the vulnerability has already been described or exploited.
In a DRAM chip, each bit of memory data is stored as the presence or absence of an electric charge on a small capacitor on the chip. [2] [3] As time passes, the charges in the memory cells leak away, so without being refreshed the stored data would eventually be lost. To prevent this, external circuitry periodically reads each cell and rewrites ...
