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.

4654 vulnerabilities reference this CWE, most recent first.

VLAI
Summary
Compress/s2: Integer Overflow or Wraparound and Out-of-bounds Write in compress
Details

Signed Integer Overflow in s2.NewDict

Summary

A signed integer overflow vulnerability in s2.NewDict() allows an attacker to bypass repeat index validation by supplying a dictionary with a uvarint-encoded repeat value exceeding MaxInt64. When Dict.Encode() is subsequently called, the overflowed negative repeat value causes an out-of-bounds memory access via unsafe.Pointer arithmetic, crashing the process with SIGSEGV.

Package

  • Name: github.com/klauspost/compress/s2
  • Ecosystem: Go
  • Affected versions: <= v1.18.6 (all versions with NewDict function)

Severity

High (7.5) — CVSS v3.1: AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H

Vulnerability

Type

  • CWE-190: Integer Overflow or Wraparound
  • CWE-787: Out-of-bounds Write (via unsafe.Pointer)

Description

The NewDict() function reads a uvarint from dictionary data and converts it to int:

r, n := binary.Uvarint(dict)
// ...
d.repeat = int(r)
if d.repeat > len(dict) {
    return nil
}

When r exceeds MaxInt64 (9223372036854775807), int(r) overflows to a negative value. Since a negative number is never greater than a positive length, the validation check is bypassed.

When Dict.Encode() is called, the negative repeat value causes an integer overflow in encodeBlockDictGo():

repeat := len(dict.dict) - dict.repeat  // overflows: 62 - (-5758978476775341977) = huge positive
candidate := len(dict.dict) - repeat + s // underflows to negative
load32(dict.dict, candidate)             // OOB via unsafe.Pointer

load32 calls le.Load32 which uses unsafe.Pointer arithmetic without bounds checking:

func Load32[I Indexer](b []byte, i I) uint32 {
    return *(*uint32)(unsafe.Add(unsafe.Pointer(unsafe.SliceData(b)), i))
}

This causes a segmentation fault (SIGSEGV) when the negative index is dereferenced.

PoC

package main

import (
    "encoding/binary"
    "fmt"
    "github.com/klauspost/compress/s2"
)

func main() {
    var dictData []byte
    buf := make([]byte, binary.MaxVarintLen64)
    n := binary.PutUvarint(buf, 12687765596934209639) // > MaxInt64
    dictData = append(dictData, buf[:n]...)
    dictData = append(dictData, make([]byte, 16)...) // minimum dict size

    dict := s2.NewDict(dictData)
    // dict is non-nil despite invalid repeat value (overflow bypassed validation)

    src := make([]byte, 64)
    for i := range src { src[i] = byte(i) }
    dict.Encode(nil, src) // SIGSEGV: OOB access via unsafe.Pointer
}

Impact

  • Denial of Service: The process crashes immediately with SIGSEGV

Attack Vector

Any application that: 1. Accepts user-supplied S2 dictionary data via s2.NewDict() 2. Calls Dict.Encode() on any data ≥32 bytes

Suggested Fix

Validate the uvarint value before converting to int:

if r > math.MaxInt64 {
    return nil
}
d.repeat = int(r)

Or use uint for the repeat field and validate against uint(len(dict)).

GHSA-25PH-29M7-X9XV

Vulnerability from github – Published: 2022-05-13 01:01 – Updated: 2022-05-13 01:01
VLAI
Details

An exploitable integer overflow exists in the 'multires_load_old_dm' functionality of the Blender open-source 3d creation suite v2.78c. 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 a .blend file in order to trigger this vulnerability.

GHSA-265R-HFXG-FHMG

Vulnerability from github – Published: 2025-03-17 21:24 – Updated: 2025-05-05 00:30
VLAI
Summary
containerd has an integer overflow in User ID handling
Details

Impact

A bug was found in containerd where containers launched with a User set as a UID:GID larger than the maximum 32-bit signed integer can cause an overflow condition where the container ultimately runs as root (UID 0). This could cause unexpected behavior for environments that require containers to run as a non-root user.

Patches

This bug has been fixed in the following containerd versions:

  • 2.0.4 (Fixed in https://github.com/containerd/containerd/commit/1a43cb6a1035441f9aca8f5666a9b3ef9e70ab20)
  • 1.7.27 (Fixed in https://github.com/containerd/containerd/commit/05044ec0a9a75232cad458027ca83437aae3f4da)
  • 1.6.38 (Fixed in https://github.com/containerd/containerd/commit/cf158e884cfe4812a6c371b59e4ea9bc4c46e51a)

Users should update to these versions to resolve the issue.

Workarounds

Ensure that only trusted images are used and that only trusted users have permissions to import images.

The containerd project would like to thank Benjamin Koltermann and emxll for responsibly disclosing this issue in accordance with the containerd security policy.

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.
