## What is CVE-2024-11498?

CVE-2024-11498 is a medium-severity denial of service vulnerability in libjxl, published on 25 Nov 2024. Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.

### Official description

There exists a stack buffer overflow in libjxl. A specifically-crafted file can cause the JPEG XL decoder to use large amounts of stack space (up to 256mb is possible, maybe 512mb), potentially exhausting the stack. An attacker can craft a file that will cause excessive memory usage. We recommend upgrading past commit 65fbec56bc578b6b6ee02a527be70787bbd053b0.

Weakness: CWE-400 (Uncontrolled Resource Consumption)

Check this codebase for CVE-2024-11498 and fix it if it is affected.

What it is: CVE-2024-11498 is a medium-severity denial of service vulnerability in libjxl, published on 25 Nov 2024. Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.
Exploitation: There is no known exploitation of CVE-2024-11498 in the wild and no public exploit code.

Affected product: libjxl. No package-level version data is available, so check the vendor advisory linked from the reference page.

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
