Explanation Null-pointer errors are usually the result of one or more programmer assumptions being violated. (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). Web-application scanning, also known as dynamic analysis, is a type of test that runs while an application is in a development environment. Fortify SCA is used to find and fix following software vulnerabilities at the root cause: Buffer Overflow, Command Injection, Cross-Site Scripting, Denial of Service, Format String, Integer Overflow, (Java) and to compare it with existing bug reports on the tool to test its efficacy. attacker can intentionally trigger a null pointer dereference, the 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. 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(). When you assign the value of 10 on the second line, your value of 10 is written into the memory location referred to by x. case " Null Dereference ": return 476; // Fortify reports weak randomness issues under Obsolete by ESAPI, rather than in // the Insecure Randomness category if it thinks you are using ESAPI. [REF-961] Object Management Group (OMG). Dereference before null check. How do I convert a String to an int in Java? In the following code, the programmer assumes that the system always has [1] J.

Time arrow with "current position" evolving with overlay number, Doubling the cube, field extensions and minimal polynoms. Why are trials on "Law & Order" in the New York Supreme Court? When this method is called by a thread that is not the owner, the return value reflects a best-effort approximation of current lock status. 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. Any reference to the HP and Hewlett Packard Enterprise/HPE marks is historical in nature, and the HP and Hewlett Packard Enterprise/HPE marks are the property of their respective owners. How can I find out which sectors are used by files on NTFS? which best describes the pillbugs organ of respiration; jesse pearson obituary; ion select placeholder color; best fishing spots in dupage county Dynamic analysis is a great way to uncover error-handling flaws. 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? 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. 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. There are at least three flavors of this problem: check-after-dereference, dereference-after-check, and dereference-after-store. I'll try this solution. CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): Many analysis techniques have been proposed to determine when a potentially null value may be dereferenced.

By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. The program can potentially dereference a null-pointer, thereby raising a NullPointerException. (Java) and to compare it with existing bug reports on the tool to test its efficacy. The Scope identifies the application security area that is violated, while the Impact describes the negative technical impact that arises if an adversary succeeds in exploiting this weakness. Null pointer errors are usually the result of For example, if the program calls a function to drop privileges but does not check the return code to ensure that privileges were successfully dropped, then the program will continue to operate with the higher privileges.
