Common Weakness Enumeration
- CWE-119 - Improper Restriction of Operations within the Bounds of a Memory BufferThe software performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer.
- CWE-120 - Buffer Copy without Checking Size of Input ('Classic Buffer Overflow')The program copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer, leading to a buffer overflow.
