Overview

sharp is a High performance Node.js image processing, the fastest module to resize JPEG, PNG, WebP, GIF, AVIF and TIFF images

Affected versions of this package are vulnerable to Integer Overflow in the bundled libvips GIF loader (VipsForeignLoadNsgif), which can miscompute image dimensions on 32-bit systems. An attacker can crash the process by supplying a GIF whose dimensions overflow the size calculation. Exploitation affects only 32-bit systems and requires the application to decode an untrusted GIF through sharp.

Workaround

This vulnerability can be avoided by blocking the GIF loader through sharp's block() for the VipsForeignLoadNsgif operation, or by setting the VIPS_BLOCK_UNTRUSTED environment variable, so untrusted GIF images are not decoded.

Remediation

Upgrade sharp to version 0.35.0 or higher.

Overview

sharp is a High performance Node.js image processing, the fastest module to resize JPEG, PNG, WebP, GIF, AVIF and TIFF images

Affected versions of this package are vulnerable to Out-of-bounds Read and null pointer dereference in the bundled libvips EXIF decoder, which does not validate the range of EXIF tag groups before passing them to libexif. An attacker can crash the process by supplying an image whose embedded EXIF metadata carries an out-of-range tag group. Exploitation requires the application to process an untrusted image whose EXIF metadata sharp reads.

Remediation

Upgrade sharp to version 0.35.0 or higher.

Overview

elliptic is a fast elliptic-curve cryptography implementation in plain javascript.

Affected versions of this package are vulnerable to Use of a Cryptographic Primitive with a Risky Implementation due to the incorrect computation of the byte-length of k value with leading zeros resulting in its truncation. An attacker can obtain the secret key by analyzing both a faulty signature generated by a vulnerable implementation and a correct signature for the same inputs.

Note:

There is a distinct but related issue CVE-2024-48948.

Remediation

There is no fixed version for elliptic.

Overview

uuid is a RFC4122 (v1, v4, and v5) compliant UUID library.

Affected versions of this package are vulnerable to Improper Validation of Specified Index, Position, or Offset in Input due to accepting external output buffers but not rejecting out-of-range writes (small buf or large offset). This inconsistency allows silent partial writes into caller-provided buffers.

PoC

cd /home/StrawHat/uuid
npm ci
npm run build

node --input-type=module -e "
import {v4,v5,v6} from './dist-node/index.js';
const ns='6ba7b810-9dad-11d1-80b4-00c04fd430c8';
for (const [name,fn] of [
  ['v4',()=>v4({},new Uint8Array(8),4)],
  ['v5',()=>v5('x',ns,new Uint8Array(8),4)],
  ['v6',()=>v6({},new Uint8Array(8),4)],
]) {
  try { fn(); console.log(name,'NO_THROW'); }
  catch(e){ console.log(name,'THREW',e.name); }
}"

Remediation

Upgrade uuid to version 11.1.1, 14.0.0 or higher.

Overview

Affected versions of this package are vulnerable to Use of Externally-Controlled Input to Select Classes or Code ('Unsafe Reflection') in the deserializeErrors function during SSR hydration. An attacker can cause unexpected constructor execution on the client, potentially resulting in outbound network traffic, by supplying crafted input that overwrites certain aspects of errors caught by the SSR process.

Note: This is only exploitable if the application is running in Framework Mode or Data Mode and performs manual SSR/hydration with code that allows attacker-controlled input to influence error deserialization.

Remediation

Upgrade react-router to version 7.18.0 or higher.
