Techniques & Countermeasures

• CWE-119•Improper Restriction of Operations within the Bounds of a Memory Buffer

  The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.

• 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).
