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)

Split-royalty percentages on a KDA asset are validated by summing per-entry values into a uint32 accumulator with no per-entry cap, so two entries near 0x80000000 wrap the sum below the 10000 (100%) limit and pass validation while each stored percentage stays astronomically large; at payout every split recipient is credited pool × hugePct / 10000 and the negative remainder is silently dropped, minting KLV out of thin air. A full working proof-of-concept is published in the GitHub Security Advisory (GHSA-cgc5-v3f2-8m2v); it is not in CISA KEV and no EPSS score was provided, but the flaw is exploitable on current mainnet and not gated by any fork flag.

Remote code execution is possible in GIMP 3.2.2 through a maliciously crafted SGI image file, exploiting an integer overflow in the application's SGI file parser. An unauthenticated remote attacker can deliver the file via email or web and, upon the victim opening it, execute arbitrary code within the GIMP process context with the privileges of the logged-in user. No active exploitation has been confirmed (not in CISA KEV), though ZDI's coordinated public disclosure via ZDI-26-459 lowers the barrier to weaponization; an upstream patch commit exists but a formally tagged fixed release has not been independently confirmed.

Remote code execution in GIMP 3.2.2 is achievable by an attacker who can convince a target user to open a specially crafted TIF file, triggering an integer overflow during buffer allocation in the TIFF parser that leads to heap corruption and arbitrary code execution in the context of the current user process. Disclosed by the Zero Day Initiative under ZDI-26-458 (ZDI-CAN-29406), the flaw is rooted in missing validation of user-supplied size data before heap allocation. No public exploit has been identified at time of analysis and the vulnerability does not appear in the CISA KEV catalog; however, an upstream fix commit is available in the GIMP GitLab repository.

HIGH POC PATCH Exploit Unlikely This Week

Integer overflow in Microsoft .NET Framework and modern .NET runtimes enables local code execution with full process compromise (C:H/I:H/A:H) across a broad product surface spanning .NET Framework 3.5 through 4.8.1, .NET 8.0, 9.0, 10.0, and Visual Studio 2022 and 2026. An attacker who can deliver crafted input processed by a vulnerable .NET application can trigger arithmetic wraparound (CWE-190) to corrupt runtime memory and execute arbitrary code within the process context. Microsoft has released patches across all affected product lines; no public exploit identified at time of analysis, and no CISA KEV listing is present.

HIGH PATCH Exploit Unlikely This Week

Local privilege escalation in Windows Projected File System (ProjFS) via an integer overflow allows an authenticated local user to gain full SYSTEM-level control over the affected host. The flaw spans a wide range of actively supported Windows releases - from Windows 10 21H2 through Windows 11 26H1, and both Windows Server 2022 and 2025 - making it a broadly applicable post-compromise escalation primitive. No public exploit code or active exploitation has been identified at time of analysis; Microsoft has released patched builds addressing the vulnerability.
