Common Weakness Enumeration

CWE-190

Allowed

Integer Overflow or Wraparound

Abstraction: Base · Status: Stable

API response cwe.mitre.org

The product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number.

4323 vulnerabilities reference this CWE, most recent first.

Title
Pillow: Integer overflow when processing fonts
Summary
Pillow is a Python imaging library. Prior to version 12.2.0, if a font advances for each glyph by an exceeding large amount, when Pillow keeps track of the current position, it may lead to an integer overflow. This issue has been patched in version 12.2.0.

CVE-2026-42217 (GCVE-0-2026-42217)

Title
OpenEXR: Shift exponent overflow in `readVariableLengthInteger()` (`ImfIDManifest.cpp`)
Summary
OpenEXR provides the specification and reference implementation of the EXR file format, an image storage format for the motion picture industry. From versions 3.0.0 to before 3.2.9, 3.3.0 to before 3.3.11, and 3.4.0 to before 3.4.11, readVariableLengthInteger() decodes a variable-length integer from untrusted EXR input without bounding the shift count. After enough continuation bytes, the code executes a left shift by 70 on a 64-bit value, which is undefined behavior. This issue has been patched in versions 3.2.9, 3.3.11, and 3.4.11.

CVE-2026-42199 (GCVE-0-2026-42199)

Vulnerability from cvelistv5 – Published: 2026-05-08 21:15 – Updated: 2026-05-11 16:00

Title
Grid: Integer Overflow in Grid::expand_rows Leads to Safe-API Undefined Behavior
Summary
Grid is a data structure grid for rust. From version 0.17.0 to before version 1.0.1, an integer overflow in Grid::expand_rows() can corrupt the relationship between the grid’s logical dimensions and its backing storage. After the internal invariant is broken, the safe API get() may invoke get_unchecked() with an invalid index, resulting in Undefined Behavior. This issue has been patched in version 1.0.1.

CVE-2026-42144 (GCVE-0-2026-42144)

Title
CImg Library: Integer overflow in PNM size check bypasses memory guard (_load_pnm)
Summary
CImg Library is a C++ library for image processing. Prior to commit 4ca26bc, there is an integer overflow vulnerability in the W*H*D size computation inside _load_pnm() that can bypass the memory allocation guard. A crafted PNM/PGM/PPM file with large dimension values causes the overflow to wrap around, allocating an undersized buffer and potentially triggering a heap buffer overflow. Any application using CImg to load untrusted image files is affected. This issue has been patched via commit 4ca26bc.

Mitigation
Requirements

Ensure that all protocols are strictly defined, such that all out-of-bounds behavior can be identified simply, and require strict conformance to the protocol.

Mitigation MIT-3
Requirements

Strategy: Language Selection

  • Use a language that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
  • If possible, choose a language or compiler that performs automatic bounds checking.
Mitigation MIT-4
Architecture and Design

Strategy: Libraries or Frameworks

  • Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid [REF-1482].
  • Use libraries or frameworks that make it easier to handle numbers without unexpected consequences.
  • Examples include safe integer handling packages such as SafeInt (C++) or IntegerLib (C or C++). [REF-106]
Mitigation MIT-8
Implementation

Strategy: Input Validation

  • Perform input validation on any numeric input by ensuring that it is within the expected range. Enforce that the input meets both the minimum and maximum requirements for the expected range.
  • Use unsigned integers where possible. This makes it easier to perform validation for integer overflows. When signed integers are required, ensure that the range check includes minimum values as well as maximum values.
Mitigation MIT-36
Implementation
  • Understand the programming language's underlying representation and how it interacts with numeric calculation (CWE-681). Pay close attention to byte size discrepancies, precision, signed/unsigned distinctions, truncation, conversion and casting between types, "not-a-number" calculations, and how the language handles numbers that are too large or too small for its underlying representation. [REF-7]
  • Also be careful to account for 32-bit, 64-bit, and other potential differences that may affect the numeric representation.
Mitigation MIT-15
Architecture and Design

For any security checks that are performed on the client side, ensure that these checks are duplicated on the server side, in order to avoid CWE-602. Attackers can bypass the client-side checks by modifying values after the checks have been performed, or by changing the client to remove the client-side checks entirely. Then, these modified values would be submitted to the server.

Mitigation MIT-26
Implementation

Strategy: Compilation or Build Hardening

Examine compiler warnings closely and eliminate problems with potential security implications, such as signed / unsigned mismatch in memory operations, or use of uninitialized variables. Even if the weakness is rarely exploitable, a single failure may lead to the compromise of the entire system.

CAPEC-92: Forced Integer Overflow

This attack forces an integer variable to go out of range. The integer variable is often used as an offset such as size of memory allocation or similarly. The attacker would typically control the value of such variable and try to get it out of range. For instance the integer in question is incremented past the maximum possible value, it may wrap to become a very small, or negative number, therefore providing a very incorrect value which can lead to unexpected behavior. At worst the attacker can execute arbitrary code.
