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. Fortify is complaining about a Null Dereference when I set a field to null: But that seems really silly. Null-pointer dereferences, while common, can generally be found and Network monitor allows remote attackers to cause a denial of service (crash) or execute arbitrary code via malformed packets that cause a NULL pointer dereference.

High severity (3.7) NULL Pointer Dereference in java-1.8.-openjdk-accessibility | CVE-2019-2962 Null-pointer exceptions usually occur when one or more of the programmer's assumptions is violated. There is no guarantee that the amount of data returned is equal to the amount of data requested. Check the results of all functions that return a value and verify that the value is non-null before acting upon it. David LeBlanc. The most common forms of API abuse are caused by the caller failing to honor its end of this contract. . Depending upon the type and size of the application, it may be possible to free memory that is being used elsewhere so that execution can continue. (Generated from version 2022.4.0.0009 of the Fortify Secure Coding Rulepacks), Fortify Taxonomy: Software Security Errors. In order to avoid data races, correctly written programs must check the result of thread synchronization functions and appropriately handle all errors, either by attempting to recover from them or reporting them to higher levels. A null-pointer dereference takes place when a pointer with a value of NULL is used as though it pointed to a valid memory area. NULL pointer dereferences usually result in the failure of the process unless exception handling (on some platforms) is available and implemented. Copyright 2023, OWASP Foundation, Inc. instructions how to enable JavaScript in your web browser. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. What fortify do not like is the fact that you initialize the variable with null first, without condition, and then change it. The code loops through a set of users, reading a private data file for each user. The text was updated successfully, but these errors were encountered: cmheazel self-assigned this Jan 8, 2018 The best way to avoid memory leaks in C++ is to have as few new/delete calls at the program level as possible ideally NONE. But the stream and reader classes do not consider it unusual or exceptional if only a small amount of data becomes available. Asking for help, clarification, or responding to other answers.

This is an example of a Project or Chapter Page. McGraw-Hill. It is important to remember here to return the literal and not the char being checked. Is it suspicious or odd to stand by the gate of a GA airport watching the planes? The program can potentially dereference a null pointer, thereby raising one or more programmer assumptions being violated. The TOP 25 Errors List will be updated regularly and will be posted at both the SANS and MITRE sites. Since the code does not check the return value from gethostbyaddr (CWE-252), a NULL pointer dereference (CWE-476) would then occur in the call to strcpy(). and John Viega.

The modules cover the full breadth and depth of topics for PCI Section 6.5 compliance and the items that are important for secure software development. Category - a CWE entry that contains a set of other entries that share a common characteristic. Many modern techniques use data flow analysis to minimize the number of false positives. What is the point of Thrower's Bandolier? Most null pointer issues result in general software reliability problems, but if attackers can intentionally trigger a null pointer dereference, they can use the resulting exception to bypass security logic or to cause the application to reveal debugging information that will be valuable in planning subsequent attacks. PS: Yes, Fortify should know that these properties are secure. This example takes an IP address from a user, verifies that it is well formed and then looks up the hostname and copies it into a buffer. Asking for help, clarification, or responding to other answers.

Veracode's dynamic analysis scan automates the process, returning detailed guidance on security flaws to help developers fix them for good. How do I connect these two faces together? (where the weakness is a quality issue that might indirectly make it easier to introduce security-relevant weaknesses or make them more difficult to detect). What is the difference between public, protected, package-private and private in Java? Base - a weakness The modules cover the full breadth and depth of topics for PCI Section 6.5 compliance and the items that are important for secure software development. "Automated Source Code Reliability Measure (ASCRM)". sanity-checked previous to use, nearly all null-pointer dereferences Not the answer you're looking for? In both of these situations, fgets() signals that something unusual has happened by returning NULL, but in this code, the warning will not be noticed. Class - a weakness that is described in a very abstract fashion, typically independent of any specific language or technology. These relationships are defined as ChildOf, ParentOf, MemberOf and give insight to similar items that may exist at higher and lower levels of abstraction. Object obj = new Object (); String text = obj.toString (); // 'obj' is dereferenced. set them to NULL once they are freed: If you are working with a multi-threaded or otherwise asynchronous (Java) and to compare it with existing bug reports on the tool to test its efficacy. CODETOOLS-7900081 Fortify: Analize and fix "Null Dereference" issues. serve to prevent null-pointer dereferences. 2006. If all pointers that could have been modified are sanity-checked previous to use, nearly all NULL pointer dereferences can be prevented. Follows a very simple code sample that should reproduce the issue: public override bool Equals (object obj) { var typedObj = obj as SomeCustomClass; if (typedObj == null) return false; return this.Name == typedObj.Name; } In this simple excerpt Fortify complains that "typedObj" can be null in the return statement. I'll update as soon as I have more information thx Thierry. Even when exception handling is being used, it can still be very difficult to return the software to a safe state of operation. What are the differences between a HashMap and a Hashtable in Java? Use of the Common Weakness Enumeration (CWE) and the associated references from this website are subject to the Terms of Use. Category:Code Quality Fortify Software in partnership with FindBugs has launched the Java Open Review (JOR) Project.

Thanks for contributing an answer to Stack Overflow! For example, if a coder subclasses SecureRandom and returns a non-random value, the contract is violated. Take the following code: Integer num; num = new Integer(10); So you have a couple of choices: Ignore the warning.
