Techniques & Countermeasures

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

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-20•Improper Input Validation

    The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly.
