Most errors and unusual events in Java result in an exception being thrown. In this case, the caller abuses the callee API by making certain assumptions about its behavior (that the return value can be used for authentication purposes). 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. NULL pointer dereferences usually result in the failure of the process unless exception handling (on some platforms) is available and implemented. How do I convert a String to an int in Java? For Benchmark, we've seen it report it both ways. String URL = intent.getStringExtra("URLToOpen"); race condition causes a table to be corrupted if a timer activates while it is being modified, leading to resultant NULL dereference; also involves locking. and Justin Schuh. 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.

Fix : Analysis found that this is a false positive result; no code changes are required. Is it suspicious or odd to stand by the gate of a GA airport watching the planes? This is not a perfect solution, since 100% accuracy and coverage are not feasible. I have a solution to the Fortify Path Manipulation issues. When a reference has the value null, dereferencing . McGraw-Hill. SSL software allows remote attackers to cause a denial of service (crash) via a crafted SSL/TLS handshake that triggers a null dereference. These may be for specific named Languages, Operating Systems, Architectures, Paradigms, Technologies, or a class of such platforms. <, [REF-18] Secure Software, Inc.. "The CLASP Application Security Process". Anyone have experience with this one? Page 183. The following code does not check to see if the string returned by getParameter() is null before calling the member function compareTo(), potentially causing a NULL dereference. How do I connect these two faces together? Connect and share knowledge within a single location that is structured and easy to search. 2016-01. If an attacker provides an address that appears to be well-formed, but the address does not resolve to a hostname, then the call to gethostbyaddr() will return NULL. Did the call to malloc() fail because req_size was too large or because there were too many requests being handled at the same time? Cross-Site Flashing. The following code shows a system property that is set to null and later dereferenced by a programmer who mistakenly assumes it will always be defined. Null-pointer dereferences, while common, can generally be found and corrected in a simple way. We recently migrated our community to a new web platform and regretably the content for this page needed to be programmatically ported from its previous wiki page. Or was it caused by a memory leak that has built up over time? This user is already logged in to another session. -Wnonnull-compare is included in -Wall. (Or use the ternary operator if you prefer). Stepson gives milf step mom deep anal creampie in big ass. Connection conn = null; Boolean myConn = false; try { if (conn == null) { conn = DatabaseUtil.getConnection (); myConn = true; } result = DbClass.getObject (conn, otherParameters); }catch (DatabaseException de) { throw de; }catch (SQLException sqle) { throw new DatabaseException ("Error Message"); }finally { if (myConn && conn != null) { try { 2005. 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. (where the weakness exists independent of other weaknesses), [REF-6] Katrina Tsipenyuk, Brian Chess report. environment, ensure that proper locking APIs are used to lock before the Staging Ground Beta 1 Recap, and Reviewers needed for Beta 2. If there is a more properplace to file these types of bugs feel free to share and I'll proceed to file the bug there. Variant level weaknesses typically describe issues in terms of 3 to 5 of the following dimensions: behavior, property, technology, language, and resource. How to tell Jackson to ignore a field during serialization if its value is null? steps will go a long way to ensure that null-pointer dereferences do not java"HP Fortify v3.50""Null Dereference"Fortifynull.

Explicitly initialize all your variables and other data stores, either during declaration or just before the first usage. The Phase identifies a point in the life cycle at which introduction may occur, while the Note provides a typical scenario related to introduction during the given phase. Network monitor allows remote attackers to cause a denial of service (crash) via a malformed RADIUS packet that triggers a null dereference. Closed; is cloned by. Generally, null variables, references and collections are tricky to handle in Java code.They are not only hard to identify but also complex to deal with. chain: unchecked return value can lead to NULL dereference. So mark them as Not an issue and move on. NULL is used as though it pointed to a valid memory area. Null-pointer exceptions usually occur when one or more of the programmer's assumptions is violated.

Explanation Null-pointer errors are usually the result of one or more programmer assumptions being violated. Most appsec missions are graded on fixing app vulns, not finding them. 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(). The lack of a null terminator in buf can result in a buffer overflow in the subsequent call to strcpy(). View - a subset of CWE entries that provides a way of examining CWE content. Category:Code Quality and Gary McGraw. If you preorder a special airline meal (e.g. 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. These relationships are defined as ChildOf, ParentOf, MemberOf and give insight to similar items that may exist at higher and lower levels of abstraction. Web-application scanning, also known as dynamic analysis, is a type of test that runs while an application is in a development environment. Null dereference is a common type of runtime failure in Java programs, and it is necessary to verify whether a dereference in the program is safe. However, the code does not check the value returned by pthread_mutex_lock() for errors. When designing a function, make sure you return a value or throw an exception in case of an error. even then, little can be done to salvage the process. Abstract. Is this from a fortify web scan, or from a static code analysis? serve to prevent null-pointer dereferences. Linux-based device mapper encryption program does not check the return value of setuid and setgid allowing attackers to execute code with unintended privileges. If a law is new but its interpretation is vague, can the courts directly ask the drafters the intent and official interpretation of their law? The program can potentially dereference a null-pointer, thereby raising a NullPointerException. clones. [REF-6] Katrina Tsipenyuk, Brian Chess How do I read / convert an InputStream into a String in Java? does pass the Fortify review. The two main view structures are Slices (flat lists) and Graphs (containing relationships between entries).

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. and Gary McGraw. If it does not exist, the program cannot perform the desired behavior so it doesn't matter whether I handle the error or allow the program to die dereferencing a null value." I believe this particular behavior is a gap in the Fortify analyzer implementation, as all other static analysis tools seem to understand the code flow and will not complain about potential null references in this case. Is it correct to use "the" before "materials used in making buildings are"? Fix: Commented out the debug lines to the logger.
