image-size through 2.0.2 contains a denial of service vulnerability that allows remote attackers to permanently block the Node.js event loop by supplying a specially crafted image buffer with a zero-valued size field in a recognized box-type. Attackers can trigger an infinite loop in the JXL or HEIF image parsers by providing a crafted image containing a box with a size of zero, causing the offset to never advance and permanently hanging the application.

GHSA-m5qc-5hw7-8vg7 — image-size Denial of Service via Infinite Loop during Image Processing

Affected: npm: image-size

### 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: ```js // 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 '` ```js // 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 ===…
