Heap Overflow - Consequences

Consequences

An accidental overflow may result in data corruption or unexpected behavior by any process which uses the affected memory area. On operating systems without memory protection, this could be any process on the system.

A deliberate exploit may result in data at a specific location being altered in an arbitrary way, or in arbitrary code being executed.

The Microsoft JPEG GDI+ vulnerability MS04-028 is an example of the danger a heap overflow can represent to a computer user.

iOS jailbreaking often uses Heap overflows to gain arbitrary code, usually for kernel exploits to achieve the ability to replace the kernel with the one jailbreak provides.

Famous quotes containing the word consequences:

    We are still barely conscious of how harmful it is to treat children in a degrading manner. Treating them with respect and recognizing the consequences of their being humiliated are by no means intellectual matters; otherwise, their importance would long since have been generally recognized.
    Alice Miller (20th century)

    War is thus divine in itself, since it is a law of the world. War is divine through its consequences of a supernatural nature which are as much general as particular.... War is divine in the mysterious glory that surrounds it and in the no less inexplicable attraction that draws us to it.... War is divine by the manner in which it breaks out.
    Joseph De Maistre (1753–1821)

    There is a delicate balance of putting yourself last and not being a doormat and thinking of yourself first and not coming off as selfish, arrogant, or bossy. We spend the majority of our lives attempting to perfect this balance. When we are successful, we have many close, healthy relationships. When we are unsuccessful, we suffer the natural consequences of damaged and sometimes broken relationships. Children are just beginning their journey on this important life lesson.
