### Official description

Multiple code execution vulnerabilities exist in the IFFOutput::close() functionality of OpenImageIO Project OpenImageIO v2.4.4.2. A specially crafted ImageOutput Object can lead to a heap buffer overflow. An attacker can provide malicious input to trigger these vulnerabilities.This vulnerability arises when the `xmax` variable is set to 0xFFFF and `m_spec.format` is `TypeDesc::UINT16`

Weakness: CWE-122 (Heap-based Buffer Overflow)

Check this codebase for CVE-2022-43600 and fix it if it is affected.

What it is: CVE-2022-43600 is a high-severity memory corruption vulnerability in Debian Debian Linux, published on 23 Dec 2022. An attacker can exploit it over the internet without logging in, with no action from the victim.
Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2022-43600 exists.

Affected product: Debian Debian Linux. 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.
