Chains can involve more than two weaknesses, and in some cases, they might have a tree-like structure. serve to prevent null-pointer dereferences. This weakness can be detected using dynamic tools and techniques that interact with the software using large test suites with many diverse inputs, such as fuzz testing (fuzzing), robustness testing, and fault injection. But attackers are skilled at finding unexpected paths through programs, particularly when exceptions are involved. chain: unchecked return value can lead to NULL dereference. Variant level weaknesses typically describe issues in terms of 3 to 5 of the following dimensions: behavior, property, technology, language, and resource. that is linked to a certain type of product, typically involving a specific language or technology. Addison Wesley. Fix: Commented out the debug lines to the logger. Connect and share knowledge within a single location that is structured and easy to search. So mark them as Not an issue and move on. Pillar - a weakness that is the most abstract type of weakness and represents a theme for all class/base/variant weaknesses related to it. I know we could change the code to remove it, but that would be changing the structure of our code because of a problem in the tool. Notice that the return value is not checked before the memcpy operation (CWE-252), so -1 can be passed as the size argument to memcpy() (CWE-805). The program can potentially dereference a null-pointer, thereby raising a NullException. A method returning a List should per convention never return null but an empty List as default "empty" value. While there The Likelihood provides information about how likely the specific consequence is expected to be seen relative to the other consequences in the list. The program can potentially dereference a null-pointer, thereby causing a segmentation fault. Het is gebruikers verboden materiaal te plaatsen waarop personen jonger dan 18 jaar worden afgebeeld. But, when you try to declare a reference type, something different happens. large number of packets leads to NULL dereference, packet with invalid error status value triggers NULL dereference, Chain: race condition for an argument value, possibly resulting in NULL dereference. For example, there may be high likelihood that a weakness will be exploited to achieve a certain impact, but a low likelihood that it will be exploited to achieve a different impact. Wij hebben geen controle over de inhoud van deze sites. I'd prefer to get rid of the finding vs. just write it off. It's simply a check to make sure the variable is not null. The program can potentially dereference a null-pointer, thereby raising a NullPointerException. Common Weakness Enumeration. It serves as a common language, a measuring stick for security tools, and as a baseline for weakness identification, mitigation, and prevention efforts. Null-pointer exceptions usually occur when one or more of the programmer's assumptions is violated. Fortify keeps track of the parts that came from the original input. NULL is used as though it pointed to a valid memory area. Returns the thread that currently owns the write lock, or null if not owned. null. Removed issues. Base level weaknesses typically describe issues in terms of 2 or 3 of the following dimensions: behavior, property, technology, language, and resource. It serves as a common language, a measuring stick for security tools, and as a baseline for weakness identification, mitigation, and prevention efforts. The Likelihood provides information about how likely the specific consequence is expected to be seen relative to the other consequences in the list.
