Type: weaknessStatus: DRAFT

Description

The software reads data past the end, or before the beginning, of the intended buffer.

Extended Description

This 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.
