Check this codebase for CVE-2007-1584 and fix it if it is affected.

What it is: CVE-2007-1584 is a medium-severity memory corruption vulnerability in Php Php, published on 21 Mar 2007. It can be exploited over the network.
Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2007-1584 exists.

Affected product: Php Php. 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.
