Description

Impact

What kind of vulnerability is it? Who is impacted?

A vulnerability discovered in the ImageSharp library, where the processing of specially crafted files can lead to excessive memory usage in the Gif decoder. The vulnerability is triggered when ImageSharp attempts to process image files that are designed to exploit this flaw.

Patches

Has the problem been patched? What versions should users upgrade to?

The problem has been patched. All users are advised to upgrade to v3.1.5 or v2.1.9.

Workarounds

Is there a way for users to fix or remediate the vulnerability without upgrading?

Before calling Image.Decode(Async), use Image.Identify to determine the image dimensions in order to enforce a limit.

Detection & mitigation playbook

Open-source dependency
  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for SixLabors.ImageSharp, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update SixLabors.ImageSharp to 2.1.9 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2024-41132 is resolved across your whole dependency graph.

  3. Workarounds

    Cap what an attacker can consume: apply request size, rate and timeout limits in front of the affected component, and run it with memory and CPU limits so exhaustion degrades one worker rather than the whole service.
