Check this codebase for CVE-2018-3624 and fix it if it is affected.

What it is: CVE-2018-3624 is a high-severity memory corruption vulnerability in Intel XMM71xx, Intel XMM72xx, Intel XMM73xx, Intel XMM74xx, Sofia 3G, Sofia 3G-R, and Sofia 3G-RW, published on 5 Apr 2018. It can only be exploited from the same machine or local network, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2018-3624 in the wild and no public exploit code.

Affected product: Intel XMM71xx, Intel XMM72xx, Intel XMM73xx, Intel XMM74xx, Sofia 3G, Sofia 3G-R, and Sofia 3G-RW. 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.
