Common Weakness Enumeration

CWE-190

Allowed

Integer Overflow or Wraparound

Abstraction: Base · Status: Stable

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.

3870 vulnerabilities reference this CWE, most recent first.

** DISPUTED ** GNOME GLib before 2.65.3 has an integer overflow, that might lead to an out-of-bounds write, in g_option_group_add_entries. NOTE: the vendor's position is "Realistically this is not a security issue. The standard pattern is for callers to provide a static list of option entries in a fixed number of calls to g_option_group_add_entries()." The researcher states that this pattern is undocumented.

There is a vulnerability in htmldoc 1.9.16. In image_load_jpeg function image.cxx when it calls malloc,'img->width' and 'img->height' they are large enough to cause an integer overflow. So, the malloc function may return a heap blosmaller than the expected size, and it will cause a buffer overflow/Address boundary error in the jpeg_read_scanlines function.

Details

An exploitable integer overflow exists in the way that the Blender open-source 3d creation suite v2.78c draws a Particle object. A specially crafted .blend file can cause an integer overflow resulting in a buffer overflow which can allow for code execution under the context of the application. An attacker can convince a user to open the file or use the file as a library in order to trigger this vulnerability.

Vulnerability from github – Published: 2025-03-11 09:30 – Updated: 2025-03-11 09:30
VLAI
Details

A vulnerability was found in libzvbi up to 0.2.43. It has been declared as problematic. Affected by this vulnerability is the function vbi_strndup_iconv_ucs2 of the file src/conv.c. The manipulation of the argument src_length leads to integer overflow. The attack can be launched remotely. The exploit has been disclosed to the public and may be used. Upgrading to version 0.2.44 is able to address this issue. The patch is named ca1672134b3e2962cd392212c73f44f8f4cb489f. It is recommended to upgrade the affected component. The code maintainer was informed beforehand about the issues. She reacted very fast and highly professional.

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.
