integer-overflow-anti-pattern

Integer overflow occurs when arithmetic operations exceed data type limits, causing unexpected program behavior and exploitable security flaws. It creates vulnerabilities, classified as CWE-190, when user-controlled inputs cause unchecked calculations leading to logic errors or buffer overflows.

Prevent integer overflow in C by performing explicit boundary checks before arithmetic calculations and using larger data types to handle expected ranges. This approach secures user-controlled inputs by identifying missing overflow checks and testing boundary values.

The best way to check for arithmetic overflow in Python and JavaScript is to use arbitrary-precision libraries or implement checks before calculations. This secures user-controlled values by ensuring operations do not exceed safe numeric limits and cause logic flaws.

Yes, this secure coding guidance works for Java financial transaction auditing by providing specific BAD and GOOD code examples to fix integer overflow issues. It audits arithmetic operations on user-supplied numbers, safeguarding against logic flaws in financial contexts.

Audit your code for missing integer overflow checks whenever it handles financial transactions, memory allocation, or any calculation involving user-supplied numbers. This practice prevents unexpected crashes and exploitable security flaws caused by exceeding data type limits.
