MemberOfViewView - a subset of CWE entries that provides a way of examining CWE content. The two main view structures are Slices (flat lists) and Graphs (containing relationships between entries).734Weaknesses Addressed by the CERT C Secure Coding Standard (2008)
HasMemberClassClass - a weakness that is described in a very abstract fashion, typically independent of any specific language or technology. More specific than a Pillar Weakness, but more general than a Base Weakness. Class level weaknesses typically describe issues in terms of 1 or 2 of the following dimensions: behavior, property, and resource.119Improper Restriction of Operations within the Bounds of a Memory Buffer
HasMemberVariantVariant - a weakness that is linked to a certain type of product, typically involving a specific language or technology. More specific than a Base weakness. Variant level weaknesses typically describe issues in terms of 3 to 5 of the following dimensions: behavior, property, technology, language, and resource.129Improper Validation of Array Index
HasMemberVariantVariant - a weakness that is linked to a certain type of product, typically involving a specific language or technology. More specific than a Base weakness. Variant level weaknesses typically describe issues in terms of 3 to 5 of the following dimensions: behavior, property, technology, language, and resource.467Use of sizeof() on a Pointer Type
HasMemberBaseBase - a weakness that is still mostly independent of a resource or technology, but with sufficient details to provide specific methods for detection and prevention. Base level weaknesses typically describe issues in terms of 2 or 3 of the following dimensions: behavior, property, technology, language, and resource.469Use of Pointer Subtraction to Determine Size
HasMemberClassClass - a weakness that is described in a very abstract fashion, typically independent of any specific language or technology. More specific than a Pillar Weakness, but more general than a Base Weakness. Class level weaknesses typically describe issues in terms of 1 or 2 of the following dimensions: behavior, property, and resource.665Improper Initialization
HasMemberBaseBase - a weakness that is still mostly independent of a resource or technology, but with sufficient details to provide specific methods for detection and prevention. Base level weaknesses typically describe issues in terms of 2 or 3 of the following dimensions: behavior, property, technology, language, and resource.805Buffer Access with Incorrect Length Value

Relationship

In the 2008 version of the CERT C Secure Coding standard, the following rules were mapped to the following CWE IDs:

  • CWE-119 ARR00-C Understand how arrays work
  • CWE-119 ARR33-C Guarantee that copies are made into storage of sufficient size
  • CWE-119 ARR34-C Ensure that array types in expressions are compatible
  • CWE-119 ARR35-C Do not allow loops to iterate beyond the end of an array
  • CWE-129 ARR00-C Understand how arrays work
  • CWE-129 ARR30-C Guarantee that array indices are within the valid range
  • CWE-129 ARR38-C Do not add or subtract an integer to a pointer if the resulting value does not refer to a valid array element
  • CWE-467 ARR01-C Do not apply the sizeof operator to a pointer when taking the size of an array
  • CWE-469 ARR36-C Do not subtract or compare two pointers that do not refer to the same array
  • CWE-469 ARR37-C Do not add or subtract an integer to a pointer to a non-array object
  • CWE-665 ARR02-C Explicitly specify array bounds, even if implicitly defined by an initializer
  • CWE-805 ARR33-C Guarantee that copies are made into storage of sufficient size
