CERT C Secure Coding Standard (2008) Chapter 9 - Memory Management (MEM)
A category in the Common Weakness Enumeration published by The MITRE Corporation.
Categories in the Common Weakness Enumeration (CWE) group entries based on some common characteristic or attribute.
Weaknesses in this category are related to the rules and recommendations in the Memory Management (MEM) chapter of the CERT C Secure Coding Standard (2008).
The product calls free() twice on the same memory address, potentially leading to modification of unexpected memory locations.
The product generates a core dump file in a directory, archive, or other resource that is stored, transferred, or otherwise made accessible to unauthorized actors.
The product calls free() on a pointer to memory that was not allocated using associated heap allocation functions such as malloc(), calloc(), or realloc().
The product calls a function, procedure, or routine, but the caller specifies an argument that contains the wrong value, which may lead to resultant weaknesses.
The product calls a function, procedure, or routine with arguments that are not correctly specified, leading to always-incorrect behavior and resultant weaknesses.
The product does not check or incorrectly checks for unusual or exceptional conditions that are not expected to occur frequently during day to day operation of the pro...
Using realloc() to resize buffers that store sensitive information can leave the sensitive information exposed to attack, because it is not removed from memory.
The product does not initialize or incorrectly initializes a resource, which might leave the resource in an unexpected state when it is accessed or used.
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 th...
The product 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.
The product does not correctly calculate the size to be used when allocating a buffer, which could lead to a buffer overflow.
The product performs a calculation that can produce an integer overflow or wraparound, when the logic assumes that the resulting value will always be larger than the o...
A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit.
The product stores sensitive data in memory that is not locked, or that has been incorrectly locked, which might cause the memory to be written to swap files on disk b...
The product releases a resource such as memory or a file so that it can be made available for reuse, but it does not clear or "zeroize" the information contained in th...
The product does not check the return value from a method or function, which can prevent it from detecting unexpected states and conditions.
Referencing memory after it has been freed can cause a program to crash, use unexpected values, or execute code.
Wrap around errors occur whenever a value is incremented past the maximum value for its type and therefore "wraps around" to a very small, negative, or undefined value.
