Check this codebase for CVE-2018-7992 and fix it if it is affected.

What it is: CVE-2018-7992 is a medium-severity memory corruption vulnerability in Huawei Technologies Co., Ltd. MediaPad M3; Mate 9 Pro; P10 Plus, published on 31 Jul 2018. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.
Exploitation: There is no known exploitation of CVE-2018-7992 in the wild and no public exploit code.

Affected product: Huawei Technologies Co., Ltd. MediaPad M3; Mate 9 Pro; P10 Plus. 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.
