If I had to guess, the tool you're using is complaining about our use of Math.random() but we don't rely on it being cryptographically secure. The software's operation may slow down, but it should not become unstable, crash, or generate incorrect results. The method isXML () in jquery-1.4.4.js can dereference a null pointer on line 4283, thereby raising a NullExcpetion. More information is available Please select a different filter. Thank you for visiting OWASP.org. When designing a function, make sure you return a value or throw an exception in case of an error. Base level weaknesses typically describe issues in terms of 2 or 3 of the following dimensions: behavior, property, technology, language, and resource. How do I connect these two faces together?

The method isXML in jquery-1.4.4.js can dereference a null pointer on line 4283, thereby raising a NullExcpetion. But, when you try to declare a reference type, something different happens. This table specifies different individual consequences associated with the weakness. This website uses cookies to analyze our traffic and only share that information with our analytics partners. The programmer expects that when fgets() returns, buf will contain a null-terminated string of length 9 or less. These relationships are defined as ChildOf, ParentOf, MemberOf and give insight to similar items that may exist at higher and lower levels of abstraction. The lack of a null terminator in buf can result in a buffer overflow in the subsequent call to strcpy(). The following code does not check to see if memory allocation succeeded before attempting to use the pointer returned by malloc(). This user is already logged in to another session.
