## Schwachstellen-Klasse

- **CWE-121** — Stack-based Buffer Overflow
  A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function).
- **CWE-122** — Heap-based Buffer Overflow
  A heap overflow condition is a buffer overflow, where the buffer that can be overwritten is allocated in the heap portion of memory, generally meaning that the buffer was allocated using a routine such as malloc().
