|Type: weakness||Status: DRAFT|
|Abstraction Type: Base|
The software reads data past the end, or before the beginning,
of the intended buffer.
Extended DescriptionThis typically occurs when the pointer or its index is incremented or
decremented to a position beyond the bounds of the buffer or when pointer
arithmetic results in a position outside of the valid memory location to
name a few. This may result in corruption of sensitive information, a crash,
or code execution among other things.
