Integer Overflow

memory MEDIUM

Integer overflow occurs when an arithmetic operation produces a result that exceeds the maximum value a given integer type can store.

How It Works

Integer overflow occurs when an arithmetic operation produces a result that exceeds the maximum value a given integer type can store. In C/C++, this causes the value to "wrap around" to a small number—for example, if a 32-bit unsigned integer at maximum value (4,294,967,295) has 1 added, it wraps to 0. Attackers exploit this by providing carefully crafted input values that, when used in calculations, produce unexpectedly small results.

The most dangerous scenario involves memory allocation. An attacker supplies large values that overflow during size calculations (often when adding header sizes, element counts, or alignment padding), producing a small allocation size. When the program later writes the originally intended large amount of data into this undersized buffer, a heap overflow occurs. For instance: size = user_count * sizeof(struct) + header might overflow if user_count is sufficiently large, resulting in malloc() allocating a tiny buffer that subsequent operations overflow.

Integer overflows also enable logic bypasses. Length checks can be circumvented when overflowed values appear to pass validation. Loop bounds may become incorrect, causing excessive iterations or premature termination. Signed integer overflow (technically undefined behavior in C/C++) can flip positive values to negative, bypassing security checks that assume non-negative numbers.

Impact

  • Heap buffer overflow: Undersized allocations lead to memory corruption, enabling arbitrary code execution
  • Authentication bypass: Overflowed counters or size checks may skip security validations
  • Denial of service: Invalid memory operations cause crashes or infinite loops
  • Information disclosure: Incorrect bounds allow reading beyond intended memory regions
  • Privilege escalation: Combined with memory corruption, can compromise system integrity

Real-World Examples

The OpenSSH authentication bypass (CVE-2002-0639) involved an integer overflow in challenge-response handling where the number of responses could overflow, allowing authentication bypass. The overflow caused allocation of insufficient memory, which subsequent code exploited to execute arbitrary code.

ImageMagick suffered multiple integer overflow vulnerabilities (CVE-2016-3714 and related) where maliciously crafted image files with extreme dimension values caused size calculations to overflow. This resulted in small heap allocations followed by large writes, enabling remote code execution through image processing.

The Linux kernel's do_brk() function (CVE-2003-0961) contained an integer overflow when calculating memory region sizes. Attackers could wrap the size value to bypass length checks and map memory at arbitrary locations, achieving local privilege escalation.

Mitigation

  • Safe arithmetic libraries: Use compiler intrinsics (__builtin_add_overflow) or libraries (SafeInt, Rust's checked arithmetic) that detect overflow
  • Pre-calculation validation: Check that operands won't overflow before performing arithmetic operations
  • Compiler protections: Enable -ftrapv (GCC) or /RTCc (MSVC) to trap signed overflow; use UBSan for detection
  • Use larger types: Perform calculations in 64-bit integers when operands are 32-bit, verify result fits before casting down
  • Input validation: Enforce maximum reasonable values on user input before arithmetic
  • Modern languages: Use languages with overflow checking (Rust, Swift) or arbitrary precision integers (Python, Java BigInteger)
