Whenever overflow occurs, the 'overflow' property specifies whether a box is clipped to its padding edge, and if so, whether a scrolling mechanism is provided to access any clipped out content.
It affects the clipping of all of the element's content except any descendant elements (and their respective content and descendants) whose containing block is the viewport or an ancestor of the element.
Even if 'overflow' is set to 'visible', content may be clipped to a UA's document window by the native operating environment.
Buffer overflows usually arise as a consequence of a bug and the improper use of languages such as C or C++ that are not "memory-safe".
Buffer overflows are also a commonly exploited computer security risk — since program control data often sits in the memory areas adjacent to data buffers, by means of a buffer overflow condition, the computer can be made to execute arbitrary (and potentially malicious) code that is fed to the buggy program as data.
A buffer overflow exploit works by feeding the program specially crafted input content that is designed to overflow the allocated data storage buffer and change the data that follows the buffer in memory.
