## What is CVE-2024-40630?

CVE-2024-40630 is a medium-severity vulnerability in AcademySoftwareFoundation OpenImageIO, published on 15 Jul 2024. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.

### Official description

OpenImageIO is a toolset for reading, writing, and manipulating image files of any image file format relevant to VFX / animation via a format-agnostic API with a feature set, scalability, and robustness needed for feature film production. In affected versions there is a bug in the heif input functionality of OpenImageIO. Specifically, in `HeifInput::seek_subimage()`.  In the worst case, this can lead to an information disclosure vulnerability, particularly for programs that directly use the `ImageInput` APIs. This bug has been addressed in commit `0a2dcb4c` which is included in the 2.5.13.1 release. Users are advised to upgrade. There are no known workarounds for this issue.

Weakness: CWE-125 (Out-of-bounds Read)

What it is: CVE-2024-40630 is a medium-severity vulnerability in AcademySoftwareFoundation OpenImageIO, published on 15 Jul 2024. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.
Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2024-40630 exists.

Affected product: AcademySoftwareFoundation OpenImageIO. 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.
