Valgrind (/ ˈvælɡrɪnd /) [6] is a programming tool for memory debugging, memory leak detection, and profiling. Valgrind was originally designed to be a freely licensed memory debugging tool for Linux on x86, but has since evolved to become a generic framework for creating dynamic analysis tools such as checkers and profilers.
Python. PyCharm – Cross-platform Python IDE with code inspections available for analyzing code on-the-fly in the editor and bulk analysis of the whole project. PyDev – Eclipse-based Python IDE with code analysis available on-the-fly in the editor or at save time. Pylint – Static code analyzer.
It is worth noting that using PurifyPlus makes the most sense in programming languages that leave memory management to the programmer. Hence, in Java, Lisp, or Visual Basic, for example, automatic memory management reduces occurrence of any memory leaks. These languages can however still have leaks; unnecessary references to objects will ...
When a dangling pointer is used after it has been freed without allocating a new chunk of memory to it, this becomes known as a "use after free" vulnerability. [4] For example, CVE - 2014-1776 is a use-after-free vulnerability in Microsoft Internet Explorer 6 through 11 [ 5 ] being used by zero-day attacks by an advanced persistent threat .
Memory leak. In computer science, a memory leak is a type of resource leak that occurs when a computer program incorrectly manages memory allocations [ 1 ] in a way that memory which is no longer needed is not released. 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 leak – when memory usage is not tracked or is tracked incorrectly 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.

In computer programming, the lapsed listener problem is a common source of memory leaks for object-oriented programming languages, among the most common ones for garbage collected languages. [1] It originates in the observer pattern, where observers (or listeners) register with a subject (or publisher) to receive events. In basic implementation ...
