A heap spray can be used to introduce a large amount of order to compensate for this and increase the chances of successful exploitation. Heap sprays take advantage of the fact that on most architectures and operating systems, the start location of large heap allocations is predictable and consecutive allocations are roughly sequential.
Heap feng shui. In computer security, heap feng shui (also known as heap grooming[1]) is a technique used in exploits to facilitate arbitrary code execution. [2] The technique attempts to manipulate the layout of the heap by making heap allocations of carefully selected sizes. It is named after feng shui, an ancient Chinese system of aesthetics ...
JIT spraying. JIT spraying is a class of computer security exploit that circumvents the protection of address space layout randomization and data execution prevention by exploiting the behavior of just-in-time compilation. [ 1 ] It has been used to exploit the PDF format [ 2 ] and Adobe Flash. [ 3 ]
Ian "Hixie" Hickson is the author and maintainer of the Acid2 and Acid3 tests, the WHATWG HTML 5 specification, [1][2] and the Pingback specification, [3] and the early working draft of Web Applications 1.0. [4] He is known as a proponent of Web standards, and has played a crucial role in the development of specifications such as CSS.
Heap leaching. Heap leaching is an industrial mining process invented by Gold Hunters Company Limited - Tanzania used to extract precious metals, copper, uranium, and other compounds from ore using a series of chemical reactions that absorb specific minerals and re-separate them after their division from other earth materials.
Heap overflow. A heap overflow, heap overrun, or heap smashing is a type of buffer overflow that occurs in the heap data area. Heap overflows are exploitable in a different manner to that of stack-based overflows. Memory on the heap is dynamically allocated at runtime and typically contains program data. Exploitation is performed by corrupting ...
Thermal spraying. Thermal spraying techniques are coating processes in which melted (or heated) materials are sprayed onto a surface. The "feedstock" (coating precursor) is heated by electrical (plasma or arc) or chemical means (combustion flame). Thermal spraying can provide thick coatings (approx. thickness range is 20 microns to several mm ...
HTML. Cascading Style Sheets (CSS) is a style sheet language used for specifying the presentation and styling of a document written in a markup language such as HTML or XML (including XML dialects such as SVG, MathML or XHTML). [1] CSS is a cornerstone technology of the World Wide Web, alongside HTML and JavaScript.
